Skin pores can become blocked by oil, bacteria, dead skin cells and dirt. When this occurs, a pimple can develop. If the skin is repeatedly affected, acne can occur.
Common lesions in acne are called comedones: • Blackheads: pimple open at the skin surface. • Whiteheads: pimple closed just under the skin surface. • Papules: small, red bumps caused by inflamed or infected hair follicles. • Pustules: small red pimples with pus at their tips. • Nodules: solid and often painful lumps beneath the skin surface. • Cysts: large lumps beneath the skin that contain pus and are painful.
Inflammatory lesions are more likely to cause scarring to the skin.
Risk factors for developing acne include hormonal changes, certain medications, a diet high in refined sugars or carbohydrates, and having a parent who had acne. Self-care, topical creams, medication as well as in-clinic procedures can help treat acne as well as prevent scarring.
