Acne occurs when the oil-secreting glands in the skin are clogged and become inflamed or infected.
What causes acne?
1. Dead skin cell accumulation
2. Overactive sebaceous gland
Excess sebum clogs openings to hair follicles - especially those on the face, neck, chest and back. Bacteria grows in these clogged follicles. It makes blackheads or whiteheads form on the skin surface, a condition called non-inflammatory acne. Sometimes the follicle wall breaks under the pressure of this buildup. When it happens, sebum leaks into nearby tissues and forms a pustule - it is called inflammatory acne. This can create cysts. Ruptured cysts leave temporary or permanent scars.
Acne skin was improved by anti-acne combination treatment.
