AI Technical Summary

Technical Problem

Existing systems fail to diagnose the condition of a cosmetic coating on the skin after application, which affects the efficacy of the cosmetic's effects.

Method used

An estimation method using a skin condition index and a mathematical model to predict the state of a cosmetic coating on the skin without actual application, considering skin characteristics and the relationship between the skin condition index and the coating film state.

Benefits of technology

Enables accurate estimation of the cosmetic coating state on the skin, allowing evaluation of the cosmetic's functionality, such as UV protection, without applying the cosmetic.

Abstract

To provide a method of estimating the state of formation of a coating film of a specific composition that would result if the composition is applied to the skin of a user without actually applying the composition.SOLUTION: An estimation method is provided, comprising acquiring skin condition indicators indicative of skin characteristics of a user, and using the acquired skin condition indicators to estimate the state of formation of a coating film of a specific composition that would result if the composition is applied to the skin of the user.SELECTED DRAWING: Figure 4
