Our Skin is a dynamic organ that changes with seasons and environment. It also exhibits physiological fluctuations from day to night. For example, Sebum excretes the most at midday which the Transe Epidermal Water Loss (TEWL) or barrier function is at least. In the evening time skin temperature is at peaks and PH is the lowest and less sebum and losses more water. That’s why some individuals complain of drier, itchy or flare ups skin conditions at night. Therefore, skin repair and cell turnover happens mostly at night the time that body heals itself the most.
