What Are Blackheads?

What is a blackhead?

A blackhead (Blackhead) is a type of acne that appears black when sebum (oil), dead skin cells,

and bacteria accumulate inside a pore and oxidize upon contact with air. It occurs mostly in the T-zone, such as the nose, forehead, and chin, where sebum production is active.

Blackheads are a type of comedone, one of the forms of acne,

and they fall under open comedones, where the pore remains open. White, closed pores are called

whiteheads.

If your blackheads are severe or difficult to manage on your own, it is best to consult a professional

and receive appropriate treatment.

Reasons Blackheads Form

Excess sebum production:

When the sebaceous glands secrete too much sebum, it is more likely to clog pores.

Accumulation of dead skin cells:

Old keratinocytes do not shed properly and build up inside pores, where they mix with sebum.

Bacteria within hair follicles:

Bacteria that normally live on the skin (especially P. acnes) can break down sebum and

cause inflammation.

Contact with air and oxidation:

When the pore is open and the accumulated sebum and dead skin are exposed to air, they oxidize and turn black.

How to Manage Blackheads

Careful cleansing:

Use a gentle cleanser to wash your face thoroughly twice a day.

Exfoliation:

Use ingredients that help with exfoliation to remove dead skin cells periodically.

Sebum control:

This can be managed through various procedures or skincare products that help control sebum.

Avoid forceful extraction:

Squeezing blackheads by hand can irritate the pores, cause inflammation, or enlarge the pores, so be careful. Today, at Forena Clinic in Hongdae, we briefly looked at information about blackheads!
