A blemish is a form of skin imperfection that appears as a mark, spot, discolouration, patch, or other types of superficial flaw on the skin that are usually caused by irritation.
Skin blemishes are a typical skin problem for many women. Some marks are barely noticeable or cause concern, while some detract from your appearance and make you feel self-conscious. Although most blemishes are harmless and pose no health risk, some can indicate skin cancer.
