Acne is a condition that causes pimples or zits, including blackheads and whiteheads on the skin. Acne also causes red inflamed patches of the skin. It occurs when the pores on the surface of the skin become clogged. Acne is most common in teenagers, but anyone can get acne, even babies. Three out of four teenagers have some form of acne. Treatments can be topical (treatment that you apply to your skin) and / or tablets. A doctor or one of our pharmacists can advise on what treatment to use depending on the severity and type of acne. The aim is to clear spots as much as possible and to prevent scarring of the skin.
