What is acne?

See below: Acne commonly occur around puberty and due to changes in secretions of gland associated with hair follicles. The follicles get plugged with the secretion, dead cells and may get infected with bacteria. See this site for more information. http://www.mayoclinic.org/diseases-conditions/acne/basics/definition/CON-20020580

Acne: During puberty, there is an increase in sebum production in the skin. Sebum and skin debris clog pores and the blockage results in inflammation. Gently cleaning the surface of the skin and applying acne medications such as benzoyl peroxide or prescription clindamycin help reduce the bacteria and clean up to the top layer of the skin allowing the pimples/comedones to clear over time.
