Got questions about benzoyl peroxide?

What is benzoyl peroxide?
Benzoyl peroxide is part of the organic peroxide family with antibacterial and anti-inflammatory features. It can be found in the form of soaps, gels, washes and lotions with concentrations ranging from 1% to 10%. Gel formulations of benzoyl peroxide may be preferred over creams and lotions. It can sometimes be used in combination with other chemicals to help with dry and oily skin and/or with an antibiotic cream such as clindamycin and erythromycin. There have been numerous scientific trials proving effectiveness and safety.
How does benzoyl peroxide work?
When applied to the skin, it breaks down and releases oxygen reducing the growth of propionibacterium acnes, a bacteria associated in the formation of acne. It also increases cell turnaround, removing both mild blackheads and whiteheads (comedones) in the skin.
How should benzoyl peroxide be used?
It should be applied to the entire affected area, usually in the morning and evening. It can be sometimes used in combination with a retinoid or topical antibiotic.
What are the side effects of benzoyl peroxide?
All medications have some side effects so it is important to be aware, however do not be alarmed. The most common side effect is skin irritation. Other side effects include erythema, peeling, and dryness but these can usually be reduced by using lower concentrations.
