Using benzoyl peroxide I never noticed some exaggerated side effects. Maybe, because my skin was already too much irritated so it would be difficult to differentiate now what was an side effect and what wasn't. But, as I found on some sites, there may be some side effects in benzoyl peroxide usage, so I decided to post them here.



Serious side effects are not likely to occur. Stop using benzoyl peroxide topical and seek emergency medical attention if you experience an allergic reaction (shortness of breath; closing of the throat; swelling of the lips, face, or tongue; or hives).
Some burning, stinging, tingling, itching, redness, dryness, peeling, or irritation may be experienced while using benzoyl peroxide topical. Contact your doctor if these side effects are excessive. Less frequent application of benzoyl peroxide topical may be necessary.
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.



Some problems with using benzoyl peroxide include:

1. Dryness of the treated area. If the skin is visibly scaly, apply a light non-oily moisturizer.
   
2. Skin irritation is rarely severe. Occasionally excessive irritation may lead to discontinuing use. Consider applying benzoyl peroxide less frequently.
   
3. Contact dermatitis (red, dry, itchy skin) can be due to irritation or allergy. It can be treated with a topical steroid such as hydrocortisone cream. Contact a physician if the irritation is persistent.
   
4. Benzoyl peroxide can bleach clothing. Make sure the treated area is completely dry before it touches clothing or bedding.

• Burning
  
• Blistering
  
• Excessive itching
