These Nodular Acne pictures will give you some examples and show you what Nodular Acne can look like.
Acne nodules are hard bumps, which are usually large, under the surface of the skin.
Nodules and cysts are a much more serious form of acne than whiteheads and blackheads.
Nodules are one of the inflammatory acne lesions that appear and spread on the skin during severe acne breakouts.
When a nodule heals it leaves an acne scar behind.
