The basic cause of acne is still unknown. It seems to be a multifactorial disease in which interaction of several factors play an important part in the pathogenesis. The primary event may be (a) obstruction of the sebaceous duct due to alteration in the pattern of keratinization within the follicle, (b) abnormal sebum production with excess quantities or altered composition or (c) increased bacterial colonization (proprionibacterium acnes and staphylococcus epidermi¬dis of pilosebaceous follicles which furnish the lipases responsible for hydrolysis of sebum triglycerides into free fatty acids. All three mechanisms may be involved. Obstruction of duct leads to forma¬tion of a comedone, the initial lesion of acne. A comedone can be located either in a closed follicle as a 'white head' consisting of lipid and keratin, or in an open follicle as 'black head' consisting of keratin and lipid with melanin deposition. The continual accumula¬tion of keratin and lipid may lead to rupture of the follicular wall and release of its contents into the surrounding dermis provoking an inflammatory tissue reaction.
Benzoyl peroxide is the main ingredient for most acne treating products on the market. The reason for that is because it is highly effective on any kinds of acne, including whiteheads and blackheads. It effectively kills the bacterias deep under you skin, which are also the one of the main contributing factors to acne. Benzoyl peroxide is also cheap and there is no reason for you to not afford to have it at your finger tips when you want to remove those blackheads. Benzoyl peroxide can be irritating so you might want to take note not to overuse it. Any application more than twice a day is considered harmful to your skin.
