(3) Preferably, the nasolabial folds are used as the test sites, and the area of the test site is preferably at least 2cm×2cm.
(4) Preferably the subject has a sitting time of at least 30min, even at least 45min.
In some embodiments, referring to fig. 2, fig. 2 is a flowchart of steps S201 to S202 provided in the embodiments of the present application, where the obtaining test data of each user in the target crowd includes: the subjective data of each user is obtained through steps S201-S202, which will be described in connection with specific steps.
In step S201, a questionnaire is determined based on the product to be tested.
In step S202, the questionnaire filled in by each user is acquired; wherein the subjective data of each user is included in the questionnaire filled in by each user.
Here, the subjective data is acquired in the form of a questionnaire. The product to be tested may be determined according to the product to be tested, for example, a cosmetic product having a soothing effect, and the corresponding questionnaire may have the following problems: "do you feel that the present cosmetic has soothing function? "," how much you feel relaxed after the application of the present cosmetic? (0-100) ". Existing medical questionnaires, such as the Huaxi questionnaire, may also be used.
Illustratively, the Huaxi questionnaire questions include objective questions (subject subjective assessment questionnaire) +subjective questions (subject self-questions).
Mature questionnaires are selected that are generally accepted in the industry. The questions and answers are as follows, 1-4 points are respectively assigned to the options A-D, the options of the items of allergy history, family allergy history and facial disease history belong to "have" or "none", the "no" is set as 1 point, and the "yes" is set as 2 points; the scores are 12 to 17 for tolerance type (skin insensitivity), 18 to 23 for mild sensitivity, 24 to 32 for moderate sensitivity, and 33 to 42 for severe sensitivity.
The title may be: is there symptoms of erythema, flushing, pimple, itching, tightness, desquamation, tingling, etc. of unknown cause on your face? Whether symptoms such as erythema, flushing, pimple, itching, tightness, desquamation, stinging and the like appear on the face when the temperature of the environment changes or when the room is conditioned or windy?
