what are blemishes

Blemishes are any type of mark, spot, discoloration, or flaw that appears on the skin. In skincare, the term usually refers to acne, which can appear as blackheads, whiteheads, pimples, or cysts. Other types of blemishes include cold sores, rashes, age spots, birthmarks, and melasma. Acne is caused when oil, bacteria, or dirt clogs hair follicles, and it can sometimes leave dark spots, pockmarks, or scarring on the skin. Blemishes can also be caused by infections, genetics, or skin cancer. While most blemishes are harmless, some people may wish to treat them for cosmetic reasons. Treatment options depend on the type of blemish and may include topical creams, such as benzoyl peroxide, or medical treatment for serious conditions like skin cancer. Its important to avoid touching the skin too much when dealing with blemishes, as this can cause bacteria to spread.
