In the first example, the dynamic wrinkles to test are crow's feet wrinkles. The system 100 is used to observe the effect of a cosmetic product on a user before and after using that cosmetic product for a predefined period. In the first example, the cosmetic product can be an anti-wrinkle cream that can be applied to any area of the user's body and the predefined period can be set to four weeks.

Before using this anti-wrinkle cream, a first set of ten continuous images is obtained by the image acquisition device 102 throughout the process from the user's neutral expression to the user's maximum expression. . For example, this first set of ten continuous images can be obtained by three high-speed cameras with 3 flashlights respectively from the front, left side and right side of the user simultaneously. Only ten continuous images are illustrated and any number of images may be used in the context of the disclosure. Memory 103a stores this first set of ten continuous images in real time and the crow's feet area in these images is analyzed to obtain ten clinical ratings for the crow's feet area, such as based on the Aging Atlas. , as shown in a curve with small inverted triangles on the .

Likewise, after applying this anti-wrinkle cream for four weeks, a second set of ten continuous images is obtained by the image acquisition device 102 throughout the process, from the neutral expression of the user to the maximum expression of the user. For example, this second set of ten continuous images can be obtained by three high-speed cameras with 3 flashlights respectively to the front, left and right of the user simultaneously. Memory 103a stores this second set of ten continuous images in real time and analyzes the crow's feet area in these images to obtain ten clinical ratings for the crow's feet area, such as based on aging of the atlas. , as shown in a curve with small solid dots on the .

There illustrates a second example of application of the system 100 in accordance with the invention.

In the second example, the dynamic wrinkles to test are the nasolabial folds. The system 100 is used to observe the effect of a cosmetic product on a user before and after using that cosmetic product for a predefined period. In the second example, the cosmetic product can also be an anti-wrinkle cream which can be applied to any area of the user's body and the predefined period can be set to four weeks.

Before using this anti-wrinkle cream, a first set of ten continuous images is obtained by the image acquisition device 102 throughout the process from the user's neutral expression to the user's maximum expression. . For example, this first set of ten continuous images can be obtained by three high-speed cameras with 3 flashlights respectively from the front, left side and right side of the user simultaneously. Only ten continuous images are illustrated and any number of images may be used in the context of the disclosure. Memory 103a stores this first set of ten continuous images in real time and the nasolabial fold area of these images is analyzed to obtain ten clinical ratings for the nasolabial fold area, as illustrated in a curve with small inverted triangles on there .

Likewise, after four weeks of use of this anti-wrinkle cream, a second set of ten continuous images is obtained by the image acquisition device 102 throughout the process, from the neutral expression of the user to the maximum expression of the user. For example, this second set of ten continuous images can be obtained by three high-speed cameras with 3 flashlights respectively to the front, left and right of the user simultaneously. Memory 103a stores this second set of ten continuous images in real time and the nasolabial fold area in these images is analyzed to obtain ten clinical ratings for the nasolabial fold area, as based on the Aging Atlas, as shown in a curve with small solid points on the .

As shown in the , from a comparison between two curves for T0 and T4w, it can be seen that ten clinical ratings for nasolabial folds before and after using this anti-wrinkle cream are reduced during the whole process, from the neutral expression of the The user to the maximum expression of the user and therefore the anti-wrinkle effect for the nasolabial fold area is evident.

If the operator of the computing device 103 finds that the limits of the plurality of first images and the boundaries of the plurality of second images are not aligned with each other by components included in the computing device 103 to obtain the effect of folding of the images between the shooting times in real time, the User can be repositioned by adjusting the head support and height ruler so as to achieve the effect of folding images between different shooting times in real time. During the repositioning process, the test user is first fine-tuned by adjusting the angles and positions of the faces. Then, if necessary, the height of the head, ears, etc. is adjusted.
