what are blackheads

Blackheads are a type of acne that appear as small bumps on the skin that are open and filled with excess oil and dead skin cells. They are called blackheads because the surface looks dark or black, but the dark color is actually caused by an irregular light reflection off the clogged follicle. Blackheads can occur anywhere on the body where there are pores, but they are most common on the face, neck, back, and chest. They are a mild form of acne and are not painful because they are not inflamed like pimples. Blackheads are caused by clogged hair follicles in the skin due to a buildup of oil, dead skin cells, and bacteria. Overproduction of sebum, irritation of the skin or surrounding follicles, hormonal changes, and some medications can all contribute to the development of blackheads. Blackheads can usually be treated with over-the-counter acne products that contain benzoyl peroxide or salicylic acid, which help to remove oil and dead skin cells that clog pores. It is important to never squeeze or pick at blackheads, as this can damage the skin and lead to further breakouts.
