Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In this disclosure, the terms "more than" and "less than" may be used to compare numerical values, but these may be read as "more than" (higher, larger) and "less than" as appropriate to the extent that they do not contradict each other. is possible and vice versa.

In the present disclosure, an information processing device includes, for example, a storage circuit such as a memory, and a processing circuit such as a processor. When we say "memory," we mean not only so-called memory, but also devices and modules that can appropriately store data, such as storage areas such as various types of RAM, primary storage areas such as cache, and storage.

The information processing device may be a device in which a processor specifically implements information processing by software using hardware resources. In this case, the memory may store programs, executable files, etc. for the processor to perform information processing, and the processor may perform information processing by referring to these files stored in the memory. .

The information processing device is not limited to these, and may include a dedicated circuit for executing information processing.

FIG. 1 is a diagram illustrating an example of user classification according to an embodiment. In the present disclosure, the information processing device classifies users into categories based on skin care-related indicators, and provides skin care services for each user directly through a terminal or indirectly through a beauty staff member. Provide information regarding.

Examples of indicators related to skin care include, by way of non-limiting example, a first indicator indicating the user's sensitivity to information regarding skin care, and a second indicator indicating the self-awareness of the user's ability to assess skin conditions. In the present disclosure, explanation will be given mainly using these two indicators, but other indicators may be used as long as the indicators allow the user to appropriately classify skin care.

The user answers a questionnaire including questions regarding the first index and the second index. This questionnaire may include questions that directly indicate matters related to the first and second indicators, or may include questions that do not directly indicate (indirectly indicate) matters.

For example, a question that directly indicates matters related to the first indicator is a question such as "Do you actively obtain information about skin care?" Questions that do not directly indicate matters related to the first index are not questions that directly include matters that directly represent the first index, such as the questions above, but are questions in which the user's answer has some correlation with the first index. .

FIG. 2 is a diagram illustrating an example of a questionnaire according to an embodiment. As shown in this figure, the questionnaire includes various questions.

As a non-limiting example, direct questions regarding skin care information sensitivity include:
"I'm always gathering information to see if there are better skin care methods or products."
“I want to try new skin care products as soon as they come out.”
Examples include:

As a non-limiting example, direct questions regarding self-awareness include:
"You can tell right away whether your skin is in good condition"
"You can judge for yourself whether your skin is moisturized or not."
Examples include:

As shown in FIG. 2, the questionnaire may be one in which the user responds to each question using radio button format. The information processing device converts each answer input by the user into points. For example, in response to the above question, the information processing device sets 1 point for not at all, 6 points for strongly agree, and sets the user's sensory value between 2 and 5 points. The questionnaire may be of such a type that the user is asked to respond using radio buttons to choose the answer that most closely matches his or her feelings.

The information processing device may convert the user's answers into points, calculate the statistics of the points regarding the first index from the points, and use the calculated statistics as the first value. Similarly, the information processing device may calculate a point statistic related to the second index from the input points and use the calculated value as the second value.

As another example, the questionnaire may be of a format in which points are displayed to the user in advance, ranging from strongly disagree to strongly agree, and the user selects how many points to give.

The information processing device calculates, as the first value, the product of the coefficient set for each question related to the first index and the point value of the user's answer, and calculates the sum, average, etc. (i.e., (calculating the weighted sum or weighted average, etc.). Similarly, the information processing device may obtain the second value by calculating the sum or weighted average of weights based on coefficients for each question from the questions related to the second index.

The coefficient will be explained in detail later, but it may be set to a larger positive value for a question where the correlation between the height of the first index and the points is higher, and a smaller value for a question where the correlation is lower. Furthermore, the coefficient is not limited to being positive, and may be set to a negative value if there is an inverse correlation between the height of the first index and the points. The same applies to the second indicator.

For example, the information processing device sets a coefficient to multiply the points selected by the user for each item of the questionnaire shown in FIG. By calculating a weighted sum of points, etc., a first value regarding the first index and a second value regarding the second index are obtained.

Note that in the example questions above, it is assumed that a coefficient is set for either the first index or the second index, but the coefficient is not limited to this. For example, a certain question may have a correlation or an inverse correlation with both the first index and the second index. In other words, it is not excluded that a coefficient for the first index and a coefficient for the second index are respectively set for the same question. For example, in response to a question that may be related to both information sensitivity and self-awareness regarding skin care, such as "I can search for information that suits my skin condition," A coefficient may be set for each.

The answers to the questionnaire may be input by the user into the information processing device. The user may enter the questionnaire responses through the input interface of the information processing device, or may enter the questionnaire responses on a terminal device other than the information processing device, such as a smartphone or tablet terminal, and input the questionnaire responses by wired or wireless. The information may be transmitted to the information processing device via the network.

In addition, questionnaires are not input via electronic devices such as information processing devices or terminal devices, but users' paper or verbal responses to the questionnaire are input directly or indirectly into the information processing device by another person. It may be something that does.

For example, after a user answers a questionnaire using a terminal device that he or she owns, the user can go to a store or the like and receive counseling or the like based on the answers provided at the store or the like. For example, a user can respond to a questionnaire using a terminal device, on paper, or verbally at a store or the like, and receive counseling based on the answers at the store or the like.

Returning to Figure 1, the information processing device calculates a first value that quantifies the user's information sensitivity toward skin care based on the user's response to the first index, and a self-awareness level of the user's ability to assess skin condition based on the response to the second index. Obtain the digitized second value. The information processing device classifies users into four categories, as a non-limiting example, based on these first and second values. Through this process, the information processing device classifies users into a plurality of categories based on each user's information sensitivity to skin care and self-awareness of ability to assess skin condition.

The information processing device, for example, compares the first value and the first threshold value and classifies the users into a group with high information sensitivity to skin care and a group with low information sensitivity. Similarly, the information processing device, for example, compares the second value with the second threshold and classifies the users into a group with a high self-awareness level of skin condition judgment ability and a group with a low self-awareness level.

As an example, the user is a skin care sensitive user who is a type 1 skin care sensitive user whose first value is higher than the first threshold and whose second value is higher than the second threshold; A knowledge-oriented user who is in the second category who is below, a reality-oriented user who is in the third category whose first value is less than or equal to the first threshold and whose second value is higher than the second threshold, and a reality-oriented user whose first value is less than or equal to the first threshold. The user is classified as a minimum user, which is the fourth category, for which the second value is less than or equal to the second threshold. Note that the names of the categories are given as examples and are not limited to these.

Type 1 is a group with high sensitivity to information about skin care and high self-awareness in assessing skin. For example, users classified as category 1 may be users who are highly interested in skin care, are active in collecting information and participating in trials, and are determined to be able to assess their skin condition by themselves.

Type 2 is a group with high sensitivity to information about skin care, but low self-awareness in assessing skin. For example, users classified as category 2 may be users who are highly interested in skin care and actively collect information and participate in trials, but who do not think they can assess their skin condition by themselves.

Type 3 is a group with low sensitivity to information about skin care, but high self-awareness in assessing skin. For example, users classified as category 3 may be users who think they can assess their skin condition by themselves, but who have little interest in skin care and do not collect much information.

Type 4 is a group with low sensitivity to information about skin care and low self-awareness in assessing skin. For example, users classified as category 4 may be users who are not so interested in skin care, who are not active in collecting information or trying trials, and who do not think they can assess their skin condition by themselves.

By classifying users into such categories, it is possible to provide each user with information based on the information that the user usually obtains and the user's ability to discern their own skin condition.

After classifying the users, the information processing device outputs information based on the user classification. The information processing device may output information to a user or may output information to a service provider such as a beauty salon staff. That is, the user may directly refer to information regarding skin care outputted from the information processing device, or a beauty staff member or the like may transmit information regarding skin care to the user based on the information outputted from the information processing device, or Alternatively, actions may be taken based on this information.

The information processing device outputs information related to skin care based on the classification. This skin care information may include, by way of non-limiting example, at least one of information on skin care products, information on skin care methods, and information on lifestyle habits related to skin care.

Furthermore, the information processing device may output the results of beauty counseling such as skin care or the counseling method based on the classification.

In other words, as a non-limiting example, the information processing device has an output interface that presents information to the user or a beauty staff member, etc. (hereinafter referred to as the user, etc.), an interface that presents a questionnaire to the user, and an interface that receives input from the user, etc. The input interface may include an interface through which the user answers a questionnaire. Then, the information processing device can output information corresponding to the results of classifying the users based on the answers to the questionnaire to the users etc. from the output interface.

For example, the information processing device determines that a user classified as category 1 has a high interest in beauty in general, and after outputting information about skin diagnosis to such a user, actively obtains the information. Recommends products for users with detailed beauty information. Furthermore, users classified as category 1 are considered to have a higher level of awareness regarding beauty than users in other categories, so they mention the massage method to experience the product as well as how it feels the next morning after applying the product. You may also introduce tips such as aromas and pressure points.

For example, since users classified as category 2 have a wealth of knowledge about skin care, the information processing device can refer to skin diagnosis results actually performed at stores etc. as objective data, and It is possible to provide additional information related to determining the skin condition, such as the structure of the skin. The information processing device may recommend products for users who actively search for information to users classified as category 2, omitting detailed information. Furthermore, for users classified as category 2, it may be possible to refer to the massage method for experiencing the product as well as the sensation immediately after applying the product.

For example, since users classified as category 3 have a high level of self-awareness in their ability to assess skin conditions, the information processing device outputs information about skin diagnosis that is sufficient for users classified in this category. It is possible to output information about skin care that is not available in an easy-to-understand manner. For example, the information processing device can output basic information about skin care that is easy to understand or information about skin care based on self-recognized skin diagnosis to users in this category. Furthermore, for users classified as category 3, products that match their concerns may be recommended along with information that allows them to feel the difference in their skin condition.

For example, the information processing device determines that a user classified as Category 4 is a user who has skin-related concerns but has difficulty actively acquiring information, and provides an easy-to-understand method for determining skin information and an easy-to-understand product explanation. You may also output information related to skin care, including the following. Users classified as Category 4 may not be good at acquiring information on their own, so even if the information processing device outputs easy-to-understand explanations and narrows down the information to basic care methods, etc. good. The information processing device can output, for example, basic skin care products and easy-to-use products along with basic instructions on how to use them to users classified as category 4.

In this way, the information processing device according to the present embodiment provides a user experience based on classification using two axes: the user's information sensitivity regarding skin care and the user's self-awareness of skin condition assessment ability. can do.

Furthermore, the service provider may actually perform a skin diagnosis of the user at a store or the like. The service provider uses the user's self-awareness level of skin condition assessment ability acquired by the information processing device and the skin diagnosis results to determine the user's information sensitivity for skin care and self-awareness level of skin condition assessment ability, Furthermore, it becomes possible to provide better counseling based on the skin condition. Further, based on the results output by the information processing device, it is possible to provide feedback regarding the difference between the user's subjective recognition of his/her own skin condition and the actual skin diagnosis result.

The service provider can also perform a skin diagnosis by changing the skin diagnosis to be performed or the level of the skin diagnosis, etc., based on the user's self-awareness of the user's ability to assess skin conditions. That is, the information processing device obtains the skin diagnosis results, and based on the skin diagnosis results and the classified categories, selects information on skin care products, skin care methods, or lifestyle habits related to skin care. At least one of these pieces of information can be outputted, or the output representation of these pieces of information can be changed and outputted.

For example, for a user who is determined to have concerns about certain factors (for example, wrinkles, age spots, etc.) as a result of a skin diagnosis, the information processing device can output information regarding these factors. As another example, the information processing device can also change the content or expression of the information to be output based on these factors.

In this case, the skin diagnosis to be performed may be selected based not only on the self-perceived level of skin condition assessment ability but also on the groups classified by the information processing device.

Next, the selection of the first and second indicators described above, the coefficients corresponding to each indicator multiplied by the answers to each question, and statistical methods such as thresholds for classification will be explained. Note that the following description shows a non-limiting example of the present disclosure, and the technical scope of the present disclosure does not exclude forms other than those described below.

In order to appropriately classify users, the service provider defines the first index and the second index in advance, and provides coefficients for calculating the first value and the second value, and the first value and the second value. A first threshold value and a second threshold value are set for each. The index, this coefficient, and the threshold value may be determined based on the results of, for example, conducting a questionnaire (user awareness survey) including the same question items in advance. This questionnaire may be performed, for example, on a large number of randomly sampled users who regularly use lotion.

First, the method for determining the first index and second index will be explained. In order to understand the actual state of users' skin care experiences, in-depth interviews with users can be conducted for qualitative analysis, and individual differences can be examined through quantitative analysis using questionnaires.

In-depth interviews are conducted to understand the person's daily skin care behavior and thoughts, expectations, or values regarding skin care, as well as to specifically understand the situations in which they feel the effects of skin care in their daily lives.

This depth interview may be conducted as a preliminary work, for example, by having the user take a video of their skin care routine in the morning and evening using a terminal device on the user's side. Specifically, while taking privacy into consideration, we ask participants to take photos of their skin care routine from start to finish in their usual location, as much as possible.

In depth interviews, for example,
・Understanding the pattern of daily skin care behavior,
・Self-evaluation of current skin care behavior,
・When to be concerned about your skin condition,
・Understanding what constitutes good/bad skin condition and its standards;
・How to collect information related to skin care and makeup,
・How to judge which cosmetics you feel are suitable for you,
・Understanding what is most important (ideal) in skin care,
Obtain user answers for items such as:

Regarding the pattern of daily skin care behavior, for example,
- Check the video you have taken,
- Reasons for characteristic behavior, history from the past,
- Differences in behavior in different situations,
can be determined based on

Regarding when to be concerned about your skin condition, for example,
-Can you tell when it's moist and when it's not?
- What you can find out by checking your skin,
- What you understand, what you do after thinking about it,
can be determined based on

In-depth interviews may be conducted by interviewers with extensive knowledge of cosmetics, such as beauty staff or counselors. The interview content is recorded and analysis can be performed by transcribing the spoken data.

Based on the transcription of the above speech data, the structure of skin care effect perception will be analyzed using the KA method. The KA method is a qualitative analysis method, and is mainly used to understand and analyze the usage status of UX design. The KA method can extract the value of a user's actions by interpreting the reasons, motives, etc. behind them. The KA method is characterized by the belief that user actions, no matter how small, have meaning and value, and converts them into codes of ``the value of...''.

Figure 3 is a diagram showing an example of a card (KA card) used for analysis in the KA method. In the KA method, analysis is performed using this KA card. At the top of the card, data related to the user's actions are extracted from the utterance data obtained in the interview and written. In the left column, the identifier of the relevant KA card is written.

Interpret this data and write the code paraphrased in one word from the user's perspective in the "User's inner voice" column at the bottom left. The value included in the act of this data is expressed as verb + value, such as "value to do," "value to be able to do," "value to not have to do," etc. using the code that has been paraphrased after understanding the context of the data. Perform the coding and write it in the bottom right column of the KA card.

Using the values extracted in the lower right column of each KA card as clues, it is possible to perform grouping and consider conceptual structures with a higher level of abstraction. In the present disclosure, since the subject is the perceived effect of skin care actions, this KA method that can derive the value of actions can be used.

A value map is derived from the group arrangement of values using the KA method described above. A value map is a map in which similar value groups are arranged close to each other and the relationships between the value groups are structured.

The derived value map can show the cause-and-effect relationship of value across all skin care behaviors, such as selecting a skin care product, purchasing it, continuing to use it to feel its effects, and taking actions to adjust as necessary. . Any area can also be extracted from the generated value map. For example, it is also possible to extract from the value map the main elements that correspond to the perceived skin care effect.

FIG. 4 is a diagram showing an example of a value map in which main elements are extracted for the portion corresponding to the feeling of skin care effect according to one embodiment. Based on this diagram, an example of a hypothetical conceptual structure for realizing skin care effects is derived. Arrows between each group indicate relationships between the groups.

First of all, daily <E. Skin care behavior> is ``maintaining the current status while monitoring the skin condition and making adjustments as necessary.'' This adjustment differs depending on the individual, but the factors that make this difference are influenced by <C. Ability to assess skin condition>, <A. Information behavior regarding skin care>, and <B. Skin care attitude (values and expectations)>. There is. Being able to discern skin conditions is a kind of ability, but in interviews it is expressed as ``self-awareness to be able to discern skin conditions.''

Daily skin care styles are influenced by the ``basic attitude toward skin care,'' which is formed by ``information and knowledge obtained through actions,'' including past experiences. ``Basic attitudes toward skin care'' are related to mental models such as images of the effects of skin care cosmetics and their mechanisms of action, and recognition of skin conditions associated with aging.

While keeping an eye on the skin condition, adjustments can be made as needed while basically maintaining the current state, such as changing the skin care cosmetic item, changing the application method, or discontinuing it. These decisions are made while being influenced by information and basic attitudes.

Although there are individual differences in skin care behavior, it is assumed that this is due to the ability to practice skin care. This ability is the above-mentioned <C. Ability to assess skin condition>, but in addition, <A. Information behavior related to skin care> is also required to understand individual differences, such as the ability to read and understand chemical explanations of cosmetics. It is positioned as one of the abilities to produce.

<D. Realizing skin care effects> is felt in daily life as ``the effects of skin care that can be felt when touching or looking at the skin.'' Typically, this is felt when adjustments or changes are made, such as when changing skin care cosmetic items. This experience of skin care effects is also influenced by ``self-awareness of assessing skin condition.''

As mentioned earlier, daily skin care behavior is about maintaining the current skin condition while adjusting it as necessary, so if it is judged that it is okay to maintain the current condition, please refer to the "Current care". You can feel a kind of satisfaction, a sense of affirmation (continuation). This feeling of satisfaction can also be said to be one aspect of realizing skin care effects. If they realize that maintaining the status quo is not a good idea, they will take new actions such as gathering information.

As mentioned above, the conceptual structure formed is consistent with the context of the obtained utterance data and can be said to have a certain validity.

Through qualitative judgment, we formed a hypothetical conceptual structure for the actual skin care effect. By quantitatively verifying these and constructing a scale that allows them to be understood as individual characteristics, it is possible to obtain indicators that better shape the perception of skin care effects.

Quantitative research is realized, for example, by conducting a questionnaire to a research panel. Sampling of users is performed by, for example, grouping users into five-year age groups and extracting a predetermined number of users from each group. The above-mentioned coefficient and threshold value are calculated based on the responses of the sampled users to the questionnaire, and are determined together with the determination of the first index and the second index.

The survey items may be formulated based on the detailed items of the value groups of the KA method that make up the conceptual structure diagram shown in Figure 4, and may be in a form that allows you to grasp the three major elements A to C. In addition to the following items, items for understanding skin care behavior may also be set. for example,
・Multiple questions are set for each item regarding skin care attitude, skin care behavior, skin care practical ability, and perceived skin care effect.

In the following, an analysis using the results of an actual investigation will be described as a non-limiting example of the present disclosure.

A factor analysis will be performed for each of the three elements of the questions created. First, we will analyze items related to skin care attitudes and skin care behaviors. For example, a scale candidate is created by creating 26 items, performing item analysis using the maximum likelihood method and promax rotation, determining two factors from the scree plot, and reducing the number of items while determining the discriminative power. We obtained results based on 11 items. The factor loadings are shown in Figure 5 (contribution of total variance 58.7%, χ ² = 530.1, df = 34, p < .001, α = 0.87). Note that due to the large number of samples, the χ ² value is significant.

Items 1 and 2 with high loadings on the first factor are ``I think I know more about skin care than people my age,'' and ``I change my skin care methods every day depending on my skin condition.'' ”, so we named it ``Skin Care Proactive Behavior.'' Item 9, which has a high loading on the second factor, is ``I think that taking care of your skin is essential to keeping your skin young,'' indicating that skin care can keep your skin in good condition even as you get older. This is why we named it the ``Basic Attitude towards Skin Care.'' The first factor included the contents of <E. Skin care behavior> shown in Figure 4.

Analyze items related to skin care practical ability. For example, 14 items were created as candidate scales, and factor analysis was similarly performed using the maximum likelihood method and promax rotation. In the end, it consisted of 9 items. The factor loadings are shown in Figure 6 (contribution rate of total variance 64.8%, χ ² = 209.9, df = 12, p < .001, α = 0.73).

Item 1, which has a high loading on the first factor, is ``I am always gathering information to see if there are better skin care methods or products,'' and it is particularly related to the behavior of gathering new information and being proactive about trials. We named it ``Skin Care Information Sensitivity'' because it consists of items. The second factor has a high loading on item 5, ``I can tell right away whether my skin is in good condition,'' and it is composed of items that express self-awareness regarding assessing skin condition. It was named ``self-awareness''. The third factor has a high loading on item 8, ``Due to family and work commitments, I don't have enough time to spend on skin care and makeup.'' This item is mainly related to situational constraints on skin care. ” was named.

Finally, we will analyze items related to actual skin care effects. For example, 14 items were constructed as candidate scales, and factor analysis was similarly performed using the maximum likelihood method and promax rotation. In the end, there were 10 items. The factor loadings are shown in Figure 7 (contribution of total variance 63.5%, χ ² = 278.9, df = 18, p < .001, α = 0.46).

The first factor has a high loading on item 1, ``I feel that my current skin care routine is working well,'' and item 3 has a high loading, ``The products and methods I currently use for skin care are providing me with skin care results that are as expected.'' It consists of items that refer to actual skin care effects, such as "I feel like I am getting the desired results," but since the main purpose is that the results are as expected, I chose "Feeling the effects (as expected)."

The second factor has a high loading on item 5, ``I feel dissatisfied and would like to improve if possible,'' and is composed of items that indicate dissatisfaction and compromise. ” was named. The third factor has a high loading on item 8, ``I'm not particularly satisfied, but it doesn't mean I'm dissatisfied,'' and both items are neither dissatisfied nor satisfied. ” was named.

Next, we will verify the conceptual structure shown in Figure 4 using covariance structure analysis using a total of eight factor scores on the three scales derived from the above exploratory factor analysis.

Based on the structure in Figure 4, paths were set between each factor. Then, when we improved the path by referring to the index and modification index that indicates the fit, we obtained results with very good fit (χ ² = 8.19, df = 3, p = .042, GFI = 1.00 , AGFI = .997, RMSEA = .014). In this case, the factor scores of the above exploratory factor analysis were used for analysis. For this reason, both are expressed as observed variables in the path diagram. The resulting path diagram is shown in Figure 8. Note that error variables are omitted to simplify the diagram.

Based on the obtained path diagram, in order to analyze the degree of influence between each variable, we calculated the total effect taking into account indirect effects. Figure 9 shows this overall effect.

It can be seen that the basic structure is that "information sensitivity" influences "proactive behavior" (0.76), which in turn influences "feeling of effectiveness" (0.66). ``Self-perception of ability to judge skin'' also has an influence on ``positive attitude'' (0.32), ``basic attitude'' (0.35), and ``perception of effectiveness'' (0.35). Figure 4 shows that self-perception of skin discernment ability was not expected to have an effect on basic attitudes, but it was shown to have an effect on a broader range.

From the above, it can be said that the hypothetical conceptual structure derived through qualitative research was generally verified quantitatively. In particular, ``information sensitivity'' and ``self-perception of skin discernment ability'' were shown to be psychological factors that influence users' skin care behavior and ``basic attitude.'' Consequently, in the present disclosure, information sensitivity regarding skin care is used as the first index, and self-awareness of skin discernment ability is used as the second index.

In summary, as described above, it is desirable that the items of the questionnaire for performing quantitative analysis include the same items as those of the questionnaire actually analyzed by the information processing device, as well as many more items. Based on the questionnaire items for calculating the coefficients and threshold values, the coefficients and threshold values used by the information processing device according to the present disclosure can be determined based on factor analysis.

Furthermore, the indicators are not limited to the above two, but may be three or more. For example, an index such as inquisitiveness toward skin care can be set based on the results of factor analysis. In this case, the information processing device can classify users along three axes: information sensitivity to skin care, self-awareness of ability to assess skin condition, and skin care inquisitiveness. Furthermore, by setting thresholds for these three axes and classifying users, the information processing device can, for example, classify users into eight categories, and for each of these eight categories, Information related to skin care can also be output.

The threshold used for classification is, for example, calculated by calculating the first and second values of each user using the results of an awareness survey of a large number of users, and using some kind of statistical value of the many first and second values obtained. It may be calculated by

For example, the threshold may be set based on the average value, median, mode, etc. of the first value and second value of all users who gave significant answers. As an example, the average value of the first values may be used as the first threshold value, and the average value of the second values may be used as the second threshold value. Separate statistics may be set as thresholds for each axis, for example, an average value may be used as the first threshold, a mode may be used as the second threshold, etc.

In the above, the same threshold value is used for all users, but the invention is not limited to this. For example, threshold values may be set for each age group, region, or store visited.

By using the coefficients and threshold values set in this way, the information processing device can appropriately classify users along different axes and output information regarding appropriate skin care based on the classification.

The information processing device can also analyze items divided by age to obtain overall awareness and current trends for each age group, and add age-related information to the output results. .

The aspects of the present disclosure are not limited to the above-described embodiments, and include various conceivable modifications, and the effects of the present disclosure are not limited to the above-described contents. The components in each embodiment may be applied in appropriate combinations. That is, various additions, changes, and partial deletions are possible without departing from the conceptual idea and spirit of the present disclosure derived from the content defined in the claims and equivalents thereof.
