"Like other organs, the skin is also concerned by what is called chronobiology. That is, it is governed by several biological rhythms," explains Dr. Martine Baspeyras, a dermatologist specialized in chronobiology. The skin cells have a different activity during the day and night. They also have a biological rhythm of 28 days, the time they take to regenerate and rise from the deep layer of the epidermis to the surface. But with age, the rate of cell renewal slows down. Finally, the skin also undergoes changes related to the menstrual cycle and seasonal cycle."
