Blackheads are a type of acne that occur when the hair follicles become clogged with excess sebum, dead skin cells, and bacteria. They appear as small, dark bumps on the skin, most commonly on the nose, chin, and forehead.
The causes of blackheads include:
Excess sebum production: Sebum is an oil produced by the sebaceous glands that helps to keep the skin hydrated. However, when too much sebum is produced, it can clog the hair follicles, leading to blackheads.
Dead skin cells: As skin cells die and shed, they can mix with sebum and clog the hair follicles.
Bacteria: Bacteria can also play a role in the development of blackheads, as they can cause inflammation and clog the hair follicles.
There are two main types of blackheads:
Open comedones: These are the most common type of blackhead and appear as small, dark bumps on the skin’s surface. They are called “open” because the pore is open to the air, which causes the sebum and dead skin cells to oxidize and turn dark.
Closed comedones: These are also known as whiteheads and appear as small, flesh-colored bumps on the skin. The pore is closed, which prevents the sebum and dead skin cells from oxidizing, giving them a white or yellowish appearance.
Blackheads can be treated with a variety of skincare products, including cleansers, exfoliators, and acne treatments. It’s important to avoid picking at blackheads, as this can cause inflammation and scarring.
