Whiteheads
Whiteheads
Whiteheads (pronunciation: /ˈwaɪtˌhɛdz/), also known as closed comedones, are a type of acne that appear as small, white, round bumps on the skin's surface. They are caused by the accumulation of sebum and dead skin cells in the pores, which are then covered by a thin layer of skin.
Etymology
The term "whitehead" is derived from the Old English words "hwit" meaning "white" and "heafod" meaning "head", referring to the white, head-like appearance of these blemishes.
Causes
Whiteheads are primarily caused by the overproduction of sebum, a natural oil produced by the sebaceous glands in the skin. Other factors that can contribute to the formation of whiteheads include hormonal changes, certain medications, and a diet high in refined sugars and fats.
Treatment
Treatment for whiteheads typically involves the use of over-the-counter topical medications containing ingredients such as benzoyl peroxide, salicylic acid, or retinoids. In more severe cases, a dermatologist may recommend prescription medications or procedures such as chemical peels or microdermabrasion.
