Three main functions of skin
- Protective – your skin’s main job is to insulate and protect the body against invasion by bacteria and other foreign things. Quick Fact: After a sunburn, the skin breaks down and can increase the risk of infection.
- Sensory – the skin can sense 5 different kinds of stimulation: touch, pressure, heat, cold, and pain.
- Regulatory – the skin helps to control body temperature by distributing heat through the skin and by preventing dehydration.
Acne occurs when glands (called sebaceous glands) in the follicles of the skin become overactive. These glands produce sebum, an oily substance that helps to stop the skin drying out. Someone with acne produces too much sebum, which forms a plug with dead skin cells and blocks the follicle.
To treat acne wash your face and you could take medication for it too.
