Your skin is the largest organ of your body, and it is awesome.
Skin is part of our integumentary system. Its membrane and three layers of tissue—the epidermis, dermis, and hypodermis—act as an insulating shield that protects us from extreme temperatures, damaging sunlight, harmful chemicals, and infection.
It’s waterproof, it is stretchable and it is capable of repairing itself. It even cushions us when we take a fall.
