Considerations: Benzoyl peroxide is able to produce complete clearing of acne only when used in an adequate dosage and within a properly applied benzoyl peroxide regimen. Some dryness, redness, and itchiness is to be expected in the first few weeks of use.6 Scientists call this initial period the "hardening effect" of benzoyl peroxide. About 1-3% of people are allergic to benzoyl peroxide and experience an inflammation of the skin or severe crusting.3This should not be confused with the "hardening effect" of benzoyl peroxide. Benzoyl peroxide, like any other peroxide, can bleach hair and fabric.1
A 2013 study on acne vulgaris in The Nurse Practitioner concurred that a multidimensional approach to acne is usually necessary because most people have a combination of symptoms. Based on the advice of dermatologists and aestheticians, we turned our focus to regimen sets, analyzing the ingredients of more than 40 kits before finding our top picks.
This foaming cleanser is a soap-free gel that will clear away clogged pores without drying skin out. Designed not to disturb the skin’s natural moisture balance, the formula is made with astringent lavender extract to minimize pores and balance PH, while the anti-inflammatory balm mint extract soothes inflammation, giving skin a visibly clearer appearance. It uses alpha hydroxy acids and quillaja saponaria to deep clean pores and fight acne-causing bacteria.
If a pore is open, it’s called a blackhead or “open comedo”. Because of the opening, contact with the air oxidizes the dead skin cells inside the pore. The air contact turns the melanin inside them darker in color, similar to the way a peeled banana left exposed to the air will darken. This is how the blackhead forms. The color of a blackhead is not because of dirt. It’s a mixture of air and the skin pigment called melanin.
Salicylic acid and azelaic acid. Azelaic acid is a naturally occurring acid found in whole-grain cereals and animal products. It has antibacterial properties. A 20 percent azelaic acid cream seems to be as effective as many conventional acne treatments when used twice a day for at least four weeks. It's even more effective when used in combination with erythromycin. Prescription azelaic acid (Azelex, Finacea) is an option during pregnancy and while breast-feeding. Side effects include skin discoloration and minor skin irritation.
