Role of skin circadian rhythm and the effect of day and night cream: a survey on Indian dermatologists’ and cosmetologists’ views and patient experiences

Background: The skin plays different functions during the day and night to adapt to the changing environments. Various specialized creams are available to meet these skincare needs. The present study was conducted to explore the perspective of Indian dermatologists and cosmetologists on skin’s circadian rhythm and assess the effectiveness of a particular day and night cream formulation. Methods: A non-interventional, questionnaire-based study was conducted as part of a survey series on multiple dermatology products across India. Every month, a product-specific survey link was released to these registered doctors, and each doctor could take up to 10 surveys for a maximum of two products. A total of 379 healthcare professionals (HCPs) took the survey on the day and night cream and reported experiences of 2085 patients regarding the use of these products. Results: The doctors believed that for majority of the patients (1997, 97%), required day and night cream to maintain their skin’s circadian rhythm. Most patients (1440, 70%) were compliant with day and night care cream regimens. Most patients (966, 47%) were highly satisfied with the use of day and night cream, with majority of the patients (1028, 49.4%) experiencing considerable reduction in dark spots and uneven skin tone. Most patients (971, 47%) felt that the application of day and night cream left their skin moisturized and rejuvenated. Conclusions: The use of day and night cream improved skin condition and hydration, addressing circadian rhythm imbalance. Indian HCPs understand the impact of skin circadian rhythm imbalance and promote a comprehensive skincare regimen to patients.
