Black heads

What are blackheads?
Blackheads are a symptom of acne, a skin condition in which the pores of the skin become blocked.Sebum is secreted and has a protective role in keeping the skin supple and hydrated, but can be overproduced to form plugs in the pores by clumping with epidermal cells that shed from the skin.

The plugs are also known as comedones. Black-headed comedones are known as open comedones whereas white-headed comedones (so-called whiteheads) are known as closed comedones. Blackheads are open to the air; the plug turns black because the sebum becomes oxidized whereas whiteheads are not open to the air.

Causes of blackheads:
They are blocked pores, and why they develop is established as follows:
-The gland that secretes sebum is overproductive
-The hair follicle (the base and canal in the skin from which a hair grows) becomes blocked because of this excess sebum into the canal
-The plug of sebum is oxidized at the surface of the skin, turning the oily, waxy substance (which also contains dead skin cells produced at a greater rate) a black color.

Treatments for blackheads:
1-Daily cleansing of the skin affected by acne is part of managing acne.
2-People with only blackheads may find success going to the pharmacy for a gel, cream or wash that contains benzoyl peroxide, which has comedolytic and antibacterial properties (helps to both break down the plugs of sebum and to prevent inflammation caused by bacteria).
3-Antibiotics taken by mouth may also be used against mild acne, although these are not a treatment for noninflammatory blackheads specifically.
4-Picking, squeezing and popping blackheads and other acne lesions - these actions, while perhaps providing some initial satisfaction, in fact worsen lesions by causing inflammation and potential scarring
5-Abrasive scrubs for washing acne - these do not improve the condition and may cause irritation.
