SKIN CONDITION DIFFERENTIATION METHOD BASED ON PAPILLARY STRUCTURE ANALYSIS

To provide a skin condition differentiation method capable of estimating a skin condition simply, accurately, and noninvasively.SOLUTION: A method includes estimation of a skin condition using papillary structure information as an index, the papillary structure information being selected from the height of a papilla, the standard deviation of heights of papillas, the number of papillas per unit observation visual field area, papillary structure surface area per unit observation visual field area, the average of constant height cross-sectional area of papillas, the standard deviation of constant height cross-sectional area of papillas, the average of circularity of constant height cross-sections of papillas, a distance between papillas, and the standard deviation of distances between papillas.SELECTED DRAWING: Figure 1 【課題】簡便かつ高精度に、また非侵襲的に、肌状態を推定することができる肌状態の鑑別法を提供する。【解決手段】乳頭構造情報を指標として肌状態を推定することであって、乳頭構造情報が、乳頭突起の高さ、乳頭突起の高さの標準偏差、単位観察視野面積当たりの乳頭突起の個数、単位観察視野面積当たりの乳頭構造の表面積、乳頭突起の等高断面積の平均、乳頭突起の等高断面積の標準偏差、乳頭突起の等高断面の円形度の平均、乳頭突起間の距離、及び乳頭突起間距離の標準偏差から選択される。【選択図】図１
