A Study on the Analysis Method of Skin Condition through Visual Confirmation of Skin Surface

Skin condition is an important concern in beauty aspect. This study considered a rough skin condition analysis method that beauty industry workers can do through visual observation or skin condition images taken with smartphones. First, studies that combine subjective and objective evaluations were selected among degree papers and academic papers searched by keywords related to ‘skin condition’ in the Research Information Sharing Service(RISS). Among them, papers that derive correlations with visually verifiable factors were selected. Next, the relationship between factors that match subjective skin condition and objective skin measurement results and factors that can be visually identified on the skin surface was investigated. According to the study, the most suitable factor for matching subjective and objective evaluations was ‘oil volume’, which is significantly related to ‘pore’, ‘skin texture’ and ‘erythema’, which can be visually checked on the skin surface. It is believed that a rough skin condition analysis will be possible using this.
