An Overview of Methods to Characterize Skin Type: Focus on Visual Rating Scales and Self-Report Instruments

Skin type classification is important because it provides guidance for professionals and consumers to recommend select the most appropriate cosmetic products skin care protocols also in clinical research. Several methods have been proposed classifying typologies such as non-invasive bioengineering tools (examples: Corneometer® Sebumeter®), visual tactile (subjective that evaluate appearance, texture, temperature, abnormalities), artificial intelligence-based instruments rating scales, self-report instruments). Examples of known scales used classify aging are Griffiths Photonumeric Scale, Glogau SCINEXA Scale. The Fitzpatrick Phototype Classification Baumann Type System some classification. Despite diversity degree aging, data on scarce not adequately compiled. Validation larger samples with individuals different ethnicities geographic locations needed promote a more universal use. Visual interesting allow be promptly efficiently examined, without using costly or complex equipment, very useful self-assessment context.
