As with all drugs, there are bound to be side effects. The severity of the side effects depend on the individual using them because there is what is called individual variation. This means that a particular drug might cause a reaction in one individual and might produce that effect in another individual.

The most common side effect include dryness. If you experience mild dryness you can apply a light oil-free moisturizer that is non-comedogenic to prevent overdrying of your skin. If you are trying benzoyl peroxide for the first time, it is advisable to start with a low concentration (2.5%) so as to determine if your skin is sensitive to the product.

Another side effect is irritation; mild irritation can be taken care of by decreasing your frequency of use. For severe irritation however, it is advisable you discontinue use.

If you experience dermatitis (i.e. red, dry, itchy skin), it would be best you discontinue use and treat with a mild topical steroid like hydrocortisone.

Most drugs have people who are allergic to them. So if you fall into the range of people who are allergic to benzoyl peroxide (usually characterized by itching and redness), it is important you discontinue the use of the product.

CAUTION: Benzoyl peroxide can bleach hair, clothing and linen so it is important that your skin is completely dry before you touch any fabric. 

Most benzoyl peroxide products are to be used twice daily in other to achieve its result. Also stick to the regimen for about 2-3 months to obtain favourable results. 

Well hope you know a little about benzoyl peroxide and are encouraged to start using it. Like I always say, you have nothing to lose except your acne.
