Explanation:
Human skin is composed of three layers of tissue: the epidermis, dermis and hypodermis, according to the Cleveland Clinic.
The epidermis is the top, visible layer of skin and it's constantly being renewed as dead skin cells are shed on a daily basis. The main functions of the epidermis include:
Making new skin cells. New skin cells form at the bottom of the epidermis. As these newer cells form, it takes them about one month to reach the top layer of the epidermis. The new cells will replace the old cells found on the skin surface, which are dead and continuously flake off.
Giving skin its color. The epidermis contains melanocytes, which are cells that produce melanin, the pigment that gives skin its color. Melanin is also responsible for suntans and freckles.
Protecting skin. Keratin, a protein made by cells found in the epidermis, gives skin its toughness and strength, and protects skin from drying out.
