What is Benzoyl Peroxide for?

Benzoyl peroxide is a topical skin product for acne treatment. It reduces the bacteria count and oxidizes proteins produced by bacteria. It also works by decreasing the amount of free fatty acids that are irritating to the skin.

How to use it?

Benzoyl peroxide is available as a cream, gel, lotion, or face wash. It can be applied directly to the area of the skin where acne is present or used to prevent the development of acne (for example using a face wash).

 

For cream, gel, and lotion, apply Benzoyl peroxide 1-2 times per day after cleaning your face with soap and water. For cleansers, wash 1-2 times per day.

 

Products containing Benzoyl peroxide are only for those aged 12 years or above. Initially, Benzoyl peroxide can be irritating to the skin, so we suggest you start with the lowest concentration (2.5%). Lower concentrations are often just as effective, and less irritating than higher concentrations.

 

Finally, remember to wash your hands after applying Benzoyl Peroxide.

What are the side effects of Benzoyl Peroxide?

Common side effects of Benzoyl Peroxide are skin reactions, for example dry skin and redness. It can also bleach your hair and clothing.

Who should not take Benzoyl Peroxide?

  • Anyone who has an allergy to Benzoyl Peroxide.
