What Is Acne?

Acne is a disease that affects the skin's oil glands. Acne happens when oil glands attached to the hair follicles or pores.  Inside the follicles, oil carries dead skin cells to the surface of the skin.
These glands make an oily substance called sebum .  When your body produces too much sebum,the pores become sticky and clogged with oil and dead skin, resulting in the bacteria on your skin becoming infected and inflamed.

When the follicle of a skin gland clogs up,a pimple grows. Most pimples are found on the face, neck, back, chest, and shoulders. Acne is not a serious health threat, but it can cause scars.
