Used hair removal cream for 6 mins on my legs which had some scratches. now there's a lot of redness & burning bumps.is this severe and how do i treat?

RED & BURNING LEGS: HAIR REMOVAL CREAMS CAN BE VERY IRRITATING. MOST OF THEM CONTAIN CHEMICALS CALLED THIOGLYCOLATES. YOU, ESSENTIALLY, HAVE A FIRE. HOW DO YOU PUT OUT A FIRE? WATER! WATER, WATER, AND MORE WATER. COMPRESSES WITH WARM -- NOT HOT OR COLD-- WATER WITH A CLOTH. APPLY IT FOR 10 OR 15 MINUTES EVERY 3 or 4 HOURS. NO SOAP OR ANYTHING ELSE!
