Biometric Evaluation of Baumann Skin Typing

Key Points

The aim is to evaluate correlations between skin types and specific biometrics including hydration, sebum, and elasticity.
Performed biometric evaluations of Baumann skin typing
Measured sebum, hydration, TEWL, melanin index, pH, elasticity parameters
Analyzed correlations between skin scores and biometric measures
Oily vs. dry scores correlated poorly with sebum levels
Pigmented vs. non-pigmented scores correlated poorly with melanin index
Sensitive vs. resistant scores correlated fairly with TEWL and pH
Wrinkle-tight scores correlated fairly with elasticity parameters, but not with dermal density or epidermal thickness

Abstract

The oily vs. dry (O/D) score showed a poor but significant correlation with sebum, while hydration and TEWL were not significant. The pigmented vs. non-pigmented (P/NP) score demonstrated a poor but significant correlation with the melanin index. The sensitive vs. resistant (S/R) score showed fair and significant correlations with TEWL and pH. The wrinkle-tight (W/T) score showed fair and statistically significant correlations with elasticity parameters (R0 and R2), while correlations with nasolabial fold parameters, dermal density, and epidermal thickness were not significant; dermal thickness showed a poor but statistically significant correlation.
