Many people have / had acne problem at some point in their life. Acne is not dangerous, however, can be frustrating when it appears on your face. Acne is a pilosebaceous unit (PU) inflammation in skin. PU consists of hair follicle and several sebaceous glands. Sebaceous glands produce oil (sebum) to protect and keep moisture on your skin and hair. Sebum does not immediately flow onto skin surface. It is firstly released from sebaceous gland into hair follicle.

Overproduction of sebum in hair follicle causes acne. Sebum accumulation mixed with keratinocyte growth (keratinocyte is a type of skin cells that produces keratin) clogs hair follicle and becomes a suitable habitat for Propionibacterium acnes (P. acnes) bacteria to grow. P. acne produces enzymes that cause inflammation.
