Although some people think they can get the best acne treatment by mixing and matching products, this is not the recommended method of treating blemishes. Aside from doctors, few people understand how different products can react with each other. In some cases, combining two products increases how well both work. For example, green tea extract and salicylic acid complement each other. Skin care system makers usually hire doctors to help improve the effectiveness of their systems.
The best acne-fighting ingredients will offer several benefits, including reducing or eliminating excess oil and removing the dead skin that builds up and clogs your pores. There are two main chemical ingredients that are FDA approved for fighting acne and you can find them in a range of acne-fighting products, including the ones in the chart above. The natural ingredients, on the other hand, have been proven to work by scientific studies but not all have been approved by the FDA as a guaranteed acne-fighting ingredient, like tea tree oil for example. Nonetheless, you will still find a combination of these chemical and natural ingredients in many skin care products on the market, and many of them work amazingly on the right skin type.
Pustules, as their name suggests, are filled with pus. They usually have a white or yellow center surrounded by extremely inflamed skin that is pink or red. The pus isn’t just bacteria and skin cells—it contains some dead white blood cells that were trying to fight the bacteria, too. Squeezing these can cause the skin around them to darken and scar.
How to Handle It: Your best bet is benzoyl peroxide. "Benzoyl peroxide can kill acne-causing bacteria and reduce inflammation," says Zeichner. Try a cream like the La Roche-Posay Effaclar Duo Dual-Action Acne Treatment ($37), which also exfoliates with lipo-hydroxy acid. Be aware that it can seriously dry out skin so moisturize well after you use it.
Antibiotics. These work by killing excess skin bacteria and reducing redness. For the first few months of treatment, you may use both a retinoid and an antibiotic, with the antibiotic applied in the morning and the retinoid in the evening. The antibiotics are often combined with benzoyl peroxide to reduce the likelihood of developing antibiotic resistance. Examples include clindamycin with benzoyl peroxide (Benzaclin, Duac, Acanya) and erythromycin with benzoyl peroxide (Benzamycin). Topical antibiotics alone aren't recommended.
