Shiseido has discovered that the nasal skeleton structure is related to such future skin conditions as wrinkles and sagging and the characteristics of internal skin, such as tissues (e.g., capillaries). It has developed a tool for predicting skin conditions including wrinkles, sagging, and internal skin conditions that are likely to appear in the future by analyzing facial images.
Promising Tool to Develop Personalized Approches
This technology is based on the unique beauty algorithms that Shiseido has developed by combining its research findings accumulated over the course of more than 100 years.
This will enable the proposal of preventive care before skin problems appear, while also serving as a promising tool to accelerate the development of new, more personalized approaches, such as proper massage methods and internal body care.
The results of this study were presented in part at the 28
th JFACE Annual Conference (Forum Kaogaku 2023) held on October 14–15, 2023. Shiseido plans to use this technology as a measurement tool in its inner beauty business, which will officially be launched in 2024.
A person’s "current" skin condition is thought to be related to the "skin characteristics that each person is born with," combined with the effects of skin care, including UV protection, diet, exercise, sleep, smoking, and other lifestyle habits. Thus far, Shiseido has developed multiple technologies to evaluate a person’s current skin condition using facial images and has applied them to at-home self-check apps and in-store devices.
Furthermore, based on the idea that an understanding of a person’s innate skin properties might lead to the ability to address skin problems before they appear, the present study focused on nasal skeleton structure, which is highly representative of inherent personal characteristics.
Skin Conditions are Strongly Related to Nasal Features
For facial shape features, 12 items including the roundness of the eyes, length of the face, size of the lips, height of nasal bridge (nose line), and the roundness of the chin were set. As for the characteristics of skin conditions, 18 items were set as variables including lines at the corners of the eyes and sagging of the face line. These items were converted to numerical terms based on facial images obtained from 424 Asian women aged 40–59 years and a subjective evaluation by visual observation, then used for analysis.
As a result, they found that skin conditions such as wrinkles and sagging skin are strongly related to the features of the nose, in particular, "the root, bridge, and wings of the nose." Moreover, when analyzed and evaluated comprehensively, it was found that "the shape of nasal bridge and saturation of skin color" and "nasal skeleton structure and the condition inside the skin, such as the capillary density" were also related.
Using the findings of the present study, Shiseido has developed a tool to predict future skin problems and internal skin characteristics from nasal skeleton structure. The challenge in the development lied in capturing the shape of the nose accurately from images obtained with typical smartphones. The eyes and mouth have clear contours relative to the skin, so it is easy to quantitatively detect their shape features.
However, the nose, although three-dimensional, is the same color as the skin, and it was thus very difficult to precisely detect its shape and size. Accordingly, the company pushed forward with its study by focusing on the slight shadow of the nose projected on the facial image, and as a result, Shiseido was finally able to develop an image processing technology to make the precise calculation possible. This technology
successfully enabled the detection of the features of nasal skeleton structure, including the root, bridge, and wings of the nose, even with the performance of typical smartphone cameras.
By combining this image analysis technology with the knowledge of relationships between nasal skeleton structure and the conditions and the inside of the skin, the company has classified faces into 16 types and developed a tool that allows it to predict skin problems that are likely to appear in the future and internal skin conditions for each type.
With this technology, Shiseido aims to realize prevention-type care to address skin problems before they appear, in addition to improvement-type care to deal with problems that have appeared on the skin. In addition, as a way to address skin problems, it will propose various types of care for the mind and body, not only with cosmetics but also with food, exercise, and sleep, based on the relationships identified in this
study and other findings, as the company further accelerates the promotion of its 2030 vision “Personal Beauty Wellness Company.”
