“…[7][8][9] Numerous devices have been proposed in the literature to measure the thermal properties of the skin in vivo. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] More recently, wearables have emerged as a solution for continuous monitoring. [27][28][29][30][31][32][33][34][35][36][37] However, to date, only a few studies have been devoted to investigating the potential correlation between thermal parameters and relevant physiological value.…”

Background and ObjectiveSkin thermal diffusivity plays a crucial role in various applications, including laser therapy and cryogenic skin cooling.This study investigates the correlation between skin thermal diffusivity and two important skin parameters, melanin content and erythema, in a cohort of 102 participants.MethodsAn in‐house developed device based on transient temperature measurement was used to assess thermal diffusivity at different body locations. Melanin content and erythema were measured using a colorimeter. Statistical analysis was performed to examine potential correlations.ResultsThe results showed that the measured thermal diffusivity values were consistent with previous reports, with variations observed among subjects. No significant correlation was found between thermal diffusivity and melanin content or erythema. This suggests that other factors, such as skin hydration or epidermis thickness, may have a more dominant influence on skin thermal properties.ConlcusionThis research provides valuable insights into the complex interplay between skin thermal properties and physiological parameters, with potential implications for cosmetic and clinical dermatology applications.
