GENERAL HISTOLOGY

Detailed explanation-1: -Makes new skin: The epidermis continually makes new skin cells. These new cells replace the approximately 40, 000 old skin cells that your body sheds every day. You have new skin every 30 days. Protects your body: Langerhans cells in the epidermis are part of the body’s immune system.

Detailed explanation-2: -Ageing and Skin Renewal Process In adults, it takes between 28 and 42 days. In those age 50 and older, the skin renewal process can take up to 84 days. With age, it takes longer for your skin to repair and replace the damaged cells, hence the more built-up dead skin cells on the top layer of the skin.
