What is benzoyl peroxide and what does it do?

Available both over the counter and through prescription, benzoyl peroxide is a topical medication that helps to improve the appearance of acne on the skin. It can also come in combination with other acne-managing ingredients.

Once absorbed by the skin, benzoyl peroxide essentially kills certain acne-causing bacteria. Benzoyl peroxide is the active ingredient in a variety of products. Look for it in products like face washes y gels. Some benzoyl peroxide products, especially those that contain antibiotics or retinoids, are only available through prescription. For information on using over-the-counter (OTC) or prescription products, speak with a health care provider.

How to use benzoyl peroxide

Before starting with any new skin care ingredients, it's a good idea to discuss them with a dermatologist or other health care provider. And always follow the instructions on the packaging of the product.

Benzoyl peroxide comes in concentrations ranging from 2.5 percent to 10 percent. It's often formulated as a gel or cream, which is applied to acne-affected areas. While each product will be different, there is some general guidance to help manage acne:

• Clean the skin up to twice a day with a gentle cleanser and apply the product with fingertips. Avoid using tools like washcloths or sponges, which can cause irritation.
• Give acne treatment time to work. It may take several weeks or months before someone will see an effect.
• Keep hands off of the face. Touching or popping pimples can cause acne to stick around longer and can potentially cause scarring.
• Protect skin with a sun-protection factor (SPF) of 30 or higher and avoid tanning beds and the sun. Some acne medications, such as benzoyl peroxide, can make skin extra sensitive to ultraviolet (UV) light.
• Apply the product as often as the instructions say to. Some may be for daily use; some are to be used once a week.
• The most common effect is skin irritation. If there are side effects, stop using the product and contact a health care provider.

Benzoyl peroxide side effects

Common side effects of benzoyl peroxide include dryness, peeling or red skin and burning or stinging. Stop using these products if these side effects occur and consult with a health care provider.

More serious side effects include swelling and blistering of the skin. In very rare cases, use of benzoyl peroxide may lead to swelling of the face, tongue or throat and may include difficulty breathing. If the latter occurs, seek medical attention immediately.

Because benzoyl peroxide makes the skin more sensitive to the sun, avoid direct sunlight while using and make sure to appropriately apply sunscreen with an SPF 30 or higher.

A common effect is that benzoyl peroxide may bleach clothes or hair if it comes into contact.

As always, check the product label and use the product as directed.
