A person should see a dermatologist if they develop cysts, nodules, or deep, painful acne, as these severe forms often do not respond to over-the-counter treatments and can cause permanent scarring.

Cysts and nodules are large, inflamed bumps that form deep within the skin and can be especially painful. Severe acne typically involves numerous inflamed lesions beneath the skin’s surface and may affect not only the face but also the chest and back.

Dermatologists can offer specialized treatments to reduce inflammation and prevent long-term damage. These may include corticosteroid injections, prescription medications like oral antibiotics or retinoids, and, in some cases, extraction procedures. Since severe acne can leave lasting scars, seeking professional care early is essential for both skin health and cosmetic outcomes.

In short, if acne is persistent, painful, or causing nodules and cysts, consulting a dermatologist ensures proper treatment and helps prevent permanent scarring.
