Biometric Evaluation of Baumann Skin Typing

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.
