Randomized trial assesses skin reflectance in women, suggesting implications for dermatological analysis.

This study aims to evaluate skin reflectance across a broad spectral range and understand the factors influencing it.
Included 20 women aged 22–50 years with Fitzpatrick skin phototypes II–III.
Measurements taken at 14 anatomical sites with different emissometers across spectral ranges of 1.9–21 µm and 335–2500 nm.
Analysis at incidence angles of 20° and 60° to study angular effects.
Lowest reflectance recorded between 335–380 nm, 1700–2500 nm, and 1.5–21 µm.
Highest reflectance in the 590–720 nm and 700–1100 nm bands, particularly in thigh and calf regions.
Higher reflectance at 60° incidence than at 20°, with consistent spatial patterns.

Hartman-Petrycka et al. (2026) studied this question.
