Difference between Acne and Blemish

Key Difference: Acne is a disease of the skin that is characterized by presence of pimples, blackheads and whiteheads. Blemish is the condition of the skin in which skin gets decolorized or darker.

Many people consider both acne and blemish as same. However, they both refer to different things. Acne is a disease or a disorder, whereas blemish is a condition. However, they are related to each other in a way; blemishes may also occur due to acne.

The word acne is derived from acme meaning "the highest point", which comes from the Greek word akme meaning "point" or "spot" Acne is the disease that is known by Acne Vulgaris in medical terms. It is generally found in youngsters.

Plugged pores are created due to excessive production of oil and this leads to lesions like non-inflammatory open or closed comedones (whiteheads or blackheads) and inflammatory papules, pustules, and nodules (pimples). It typically affects the areas of skin with the densest population of cutaneous glands, that secrete sebum (usually into a hair follicle) for lubricating hair and skin.
