Benzoyl peroxide and salicylic acid are two commonly used products to treat acne. Available in both over-the-counter and prescription products, they are considered safe for most people and come with few side effects. Since the products are most effective at treating different types of acne, it’s important to determine which is best for your skin type.
Benefits of Benzoyl Peroxide
The American Academy of Dermatology notes that benzoyl peroxide is effective at treating acne because it removes dead skin cells, which can cause acne lesions. It is most effective at treating comedones, more commonly referred to as inflammatory acne lesions, and not likely to have an effect on blackheads or whiteheads. Benzoyl peroxide should be applied to the skin even after acne clears to prevent it from returning.
Benefits of Salicylic Acid
The American Academy of Dermatology advises the use of salicylic acid for non-inflammatory acne lesions. Salicylic acid is beneficial for this type of acne because it works to correct abnormal skin shedding, which clogs pores. By doing this, it can prevent future breakouts, but will not likely clear existing breakouts. Like benzoyl peroxide, salicylic acid should be applied continuously even after acne clears.
Types
Over-the-counter products contain anywhere from 2.5 percent to 10 percent benzoyl peroxide, according to the Mayo Clinic. The products come in a variety of forms, such as face wash, soap, lotion and spot treatments. To treat mild acne lesions, consider starting with a product that contains only 2.5 percent, since benzoyl peroxide may dry or aggravate the skin. For severe acne, prescription treatments are available that contain a higher percentage.
Over-the-counter salicylic acid acne products contain up to 2 percent of the active ingredient. These products also come in many forms such as face wash, spot treatments and masks. Stronger treatments are available by prescription only.
Warning
Products containing both salicylic acid and benzoyl peroxide can cause dryness and can be irritating to the skin. If this is a problem for you, try a product with a lower percentage of the active ingredient. You may also consider applying the product only to acne-prone areas of the skin rather than all over your face. Like many acne treatments, these products cause the skin to be more sensitive to the sun. Always wear sunscreen before venturing outdoors if you're using either product.
Benzoyl peroxide also bleaches fabrics, warns the American Academy of Dermatology. If you apply a product containing benzoyl peroxide before going to bed, you may want to place an old towel on your pillow case to avoid bleaching it. Also, wash hands thoroughly after applying to avoid bleaching anything else you touch.
Considerations
Many people are embarrassed by acne. If this is the case and over-the-counter treatments are unsuccessful, consider contacting a dermatologist. According to the American Academy of Dermatology, a dermatologist can clear up most types of acne, prevent future breakouts and even eliminate acne scars. Most prescription acne treatments are covered by insurance. However, most forms of scar removal, such as laser therapy, are not.
