For many people, hair removal creams can be applied and used without incident. If the cream is not applied properly, however--such as if it is left on too long or is applied in a very sensitive area--burns or irritation can occur. Sometimes, a burning sensation caused by hair removal cream use can be due to an allergic reaction, but it's a good idea to err on the side of caution and first treat the affected area as a chemical burn.
Run cool water on the affected area for 20 minutes. Wash the area thoroughly--without soap or body wash--and make sure that there is no residue left over from the hair removal cream. Do not scrub the area or use a loofah. If the burning sensation comes back, run cool water on it. To avoid irritating the area or exacerbating the pain, wash the burn with a relatively moderate water pressure.
Remove any clothing or accessories that are surrounding your burn or that might have the hair removal cream on it. The last thing you want to do is touch the burn site with any residual cream.
Don't put anything on the burn area: salve, ointment, butter and antibiotic cream could all cause a chemical reaction, worsening the burn, or they could make the chemical bind to the skin. Instead, wrap a sterile, dry gauze or cloth around the burn. Don't wear anything too tight or constricting, since that could irritate the burn site and cause further pain.
Make an appointment to see your doctor. If necessary, contact the Poison Control Center if you have any further concerns. If you feel sick, if the burn is bleeding or if the burnt area is on the face, hands, feet, privates or is located over a major joint, contact 911.
