Detailed explanation-1: -For most adults under 50 years old, the cycle lasts between 28 and 42 days. For adults over 50 years old, this may increase to up to 84 days, though the number varies. The time it takes for your skin to complete the skin regeneration cycle depends on a range of factors, including: your age.

Detailed explanation-2: -The epidermis constantly renews itself: New cells are made in the lower layers of the epidermis. These move to the surface within four weeks. This constant renewal serves to replace the cells that are lost and fall to the ground as tiny flakes of skin when the skin is rubbed.
