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
Acne treatments come with different ingredients and formulas, but our method for choosing the best acne products is hardly top-secret. As with all of our “best of” reviews, we looked for products that have plenty of positive reviews and a strong track record of delivering proven results over time. We ignore products that promise a quick-fix or aren’t backed by sound science. We like products with natural ingredients, but that didn’t determine our final choices. We think you’ll be well-served by the products listed here.
Although there is no one single cure for acne, we based our reviews first on what doctors are saying about these products and their ingredients. Then we did some digging into all the reviews. We ruled out those products that had primarily negative responses. After all that, we consulted natural product experts to see which system they felt were the best acne treatment.
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
