There is no medical test used to diagnose acne. A diagnosis is made only with a visual examination. Most people can recognize and diagnose acne themselves; however, there is a tendency to overreact. One zit or one pimple does not constitute a full-blown case of the disease.
However, if you are unsure if what you are experiencing is acne, or if your acne seems severe, see your dermatologist.
Some skin conditions can look remarkably similar to acne, although their causes and treatments are different. Do you have acne or an acne look-alike condition? If you are unsure, it is always wise to consult with a doctor. Common skin conditions that can be mistaken for acne include:
- Rosacea - Causes red, flushed skin with papules and pustules, especially in the nose and cheek area.
- Folliculitis - Bumps or pustules caused by inflammation of the hair follicle.
- Keratosis pilaris - Small, rough, "goose-flesh" like bumps most often found on the upper arms, thighs and buttocks, and sometimes the face.
- Miliaria rubra - Small red bumps on the surface of the skin caused by excessive heat exposure. Also known as heat rash.
