Acne - How Sebum and Skin Oil Is Key To Acne
Skin has sebaceous glands all over it except on lips. These glands produce sebum or skin oil. This oil protects the skin from harmful bacteria. Acne forms near the opening of these sebaceous glands. In normal circumstances, the cells forming the wall of the glands exfoliate from the pore opening. In certain circumstances, these cells become dysfunctional and instead of exfoliating normally, block the pore opening. This blocks sebum going out and it accumulates inside forming acne.
