A severe form of acne characterized by the presence of large, inflamed, and often painful breakouts. Nodules are larger and more serious than your typical pimple. They affect deeper layers of the skin, and can be painful.
Some experts believe the term nodular acne describes severe acne forms more accurately than does the term nodulocystic acne. In any case, nodular acne can be difficult to treat and may require the use of isotretinoin.
Nodular acne can occur on the face, back, and body. This type of acne can cause severe scarring, and should be treated by a dermatologist.
