Studying wrinkles temporarily caused by facial expressions
The length of time that wrinkles appear affects the appearance ……
Pola Chemical Industries, Ltd. (Headquarters: Yokohama City, Kanagawa Prefecture, President: Takayuki Katagiri), which is responsible for the research, development, and production of the Pola Orbis Group, conducted an impression evaluation test using videos of women’s faces and found that wrinkles caused by facial expressions We found that the faster someone disappears, the more likely they are to have a favorable impression of that person.
Our efforts to help people understand the impact wrinkles have on themselves and others
As a pioneer in wrinkle research, POLA CHEMICAL INDUSTRIES is actively conducting various surveys and research. Recently, it has become clear that even wrinkles can make a good impression if they are accompanied by facial expressions (*1), and that wrinkles that temporarily form due to facial expressions (expression wrinkles) become more difficult to disappear as we age (*2). I am heading. This time, in order to find out whether the speed at which facial wrinkles disappear affects the impression given to others, we conducted an impression evaluation using videos in which facial wrinkles disappear at different speeds. *1 Reference release: “New discovery of the effect of facial expressions through impression survey: Make your mask-free life more expressive. Even if you have wrinkles, many people will feel that facial expressions make a good impression” (Published on June 26, 2023) http://www.pola-rm.co.jp/pdf/release_20230626.pdf

Examining the impact of the speed at which facial wrinkles disappear on impressions
Utilizing technology to extract facial wrinkles from videos (*2), we asked 22 men and women in their 20s to 50s about two types of videos that differ in how long it takes for facial wrinkles to disappear, and which video they thought was better. I asked them if they felt it was a good impression.
Many people feel that the faster facial wrinkles disappear, the better their impression will be.
As a result of analyzing the responses to the questions, we found that many people felt that videos in which facial wrinkles disappear quickly gave a better impression (Figure 1, Supplementary Material 1). We also found that this tendency was stronger when evaluating videos of only the upper half of the face (Supplementary Material 2). [Image 1
We have previously reported that even if wrinkles are accompanied by facial expressions, many people will have a positive impression. It was discovered that there is a possibility that the effects can be further enhanced.
In addition, facial wrinkles tend to disappear more easily when the elasticity of the skin (the tendency of the skin to return to its original shape when pressure is removed) is greater (Supplementary Material 3). In other words, care that increases the elasticity of the skin is considered effective in bringing out the effects of facial expressions.
Appropriate care for expression wrinkles that appear temporarily can also be expected to prevent them from becoming established in the future. As a pioneer in wrinkle improvement, we will continue to conduct research that will help society as a whole live with full expression.
[Supplementary Material 1] Test method
We prepared two types of videos with different “speeds at which facial wrinkles disappear” and evaluated their impressions. [Creation of video for impression evaluation]
Model: 1 woman in her 30s and 1 woman in her 40s (consent for use in the study has been obtained)
Use videos of the entire face or just the top half

【evaluation】
Evaluators: 22 male and female employees of Pola Chemical Industries, Ltd. in their 20s to 50s (13 men, 9 women)
Evaluation method: After watching the above two videos played on the display (*3), the evaluators answered the questions.
Question: Which video do you think gives a better impression? Answer: “The previous video is more applicable,” “The previous video is somewhat more applicable,” “Both are about the same.”
“The later video is somewhat more applicable.” “The later video is more applicable.”
Implementation period: Impression evaluation test/data analysis March to October 2023
*3 In order to eliminate the influence of video display order on impressions, two types of videos were presented randomly. In addition, in order to become familiar with the task, a video of another model was watched only once immediately before the start of the evaluation. [Supplementary Material 2] Impression evaluation results when looking at only the upper half of the face
Figure 3 shows the results of a comparison between a “standard video” and a “video in which facial wrinkles disappear slowly” using a video of only the upper half of the face. Similar to the results for videos of the entire face, we found that more people responded that the videos in which facial wrinkles disappeared more quickly gave them a “favorable impression.”

Furthermore, compared to a video of the entire face, more people answered that a video of only the top half of the face, in which facial wrinkles disappear more quickly, gave a “favorable impression.” Ta. This may be due to the fact that only the upper half of the face is visible, which causes the eye to focus on the eyes. When wearing a mask to protect against viruses and pollen, facial wrinkles around the eyes can easily affect your impression.
[Supplementary Material 3] Ease of fading facial wrinkles and skin elasticity Previous research has shown that the ease with which wrinkles caused by facial expressions disappear (wrinkle recovery coefficient) is proportional to skin elasticity (*4), as shown in Figure 4. In other words, it has been suggested that the greater the elasticity of the skin, the easier it is for facial wrinkles to disappear.
*4 Skin elasticity: The tendency of the skin to return to its original state when the pressure applied to the skin is removed.
[Image 5
Previous research has also found that skin elasticity is correlated with skin protein density, as shown in Figure 5. We believe that care for the elasticity of the skin is appropriate for making it easier to eliminate wrinkles caused by facial expressions.
