What is Acne?

Acne is an infection of the skin, caused by changes in the sebaceous glands. The sebaceous glands secrete an oily substance called sebum which function is to protect and waterproof hair and skin, and keep them from becoming dry. If too much sebum is produced, it is common that oils from the glands combine with dead skin cells to block hair follicles. Under the blocked pore, oil builds up. Skin bacteria can then grow very quickly. This infection makes the skin become swollen and red, which becomes visible. The redness comes from the inflammation of the skin in response to the infection.
