Acne is a common problem of the skin’s oil glands present at the base of hair follicles. Commonly seen during puberty, acne is not a dangerous disorder or permanent, but can result in scarring. Acne scars are reddish or brownish marks left behind on the skin after a pimple/acne lesion heals.
It is commonly seen in teenagers, but many adults can also suffer from this problem. Acne scarring can be appreciated better, if we trace the development of acne.
