Purpose: This study aimed to explore the differences of the biophysical parameters in the facial skin of Beijing and Kunming females so that it can provide practical application guidance for consumers in different regions. Also, this study would help the cosmetic enterprises devise cosmetics product more targeted according to particular features of various regions. Methods: 323 healthy women aged 21-69 years, according to the inclusive and exclusive criteria, from Beijing and Kunming enrolled in this study. We measured 6 biophysical characteristics including hydration, trans-epidermal water loss (TEWL), sebum content, pH, melanin index (MI), erythema index (EI) by non-invasive method. Results: There were very significant regional differences of the skin biophysical parameters between Beijing and Kunming. In general, Kunming women showed lower sebum secretion and TEWL, higher hydration, MI and EI than Beijing women. Conclusion: Regions were an important factor which affected the skin physiological parameters. External circumstances and living habits differences were all considerations to evaluate skin condition. Research on skin biophysical parameters between different regions was essential to developing appropriate skincare strategies and devising cosmetics product more targeted.
