Benzoyl Peroxide is used for all stages of common acne. Benzoyl Peroxide attacks the
bacteria (Propionibacterium acnes) that play an essential part in causing acne. Benzoyl
Peroxide also sheds the dead cells from the skin surface and may cause dryness. You should
not use Benzoyl Peroxide if you are hypersensitive to Benzoyl Peroxide or any other
ingredients. Since this is an oxidising agent, you should not use at the same time as other
topical agents, which would react with an oxidising agent.
What you should know before using Benzoyl Peroxide.
Benzoyl Peroxide is for topical use only. This means that it is put on the skin. Do not allow
the gel to touch your eyes, mouth or the inside of your nostrils. If you expose your skin to
sun for a long time, or to strong sun, you should use a high protection sunscreen
preparation. You should also apply the gel less often than usual. Make sure that your skin is
dry when you apply Benzoyl Peroxide to avoid unnecessary irritation.
