I applied apple cider vinegar , tea tree oil and multani mitti on certain areas of face and kept it for 20mins and washed it off immediately those areas became frosted and then the next day morning they started to turn brown and i tried to peel them off and now its burning like hell and there is pinkish skin underneath it what iam i supposed to do.. I donot want it to scar . Iam applying hydrocortisone 1% cream to those areas and moisturising them what all precautions iam i supposed to take ? treatment ? and how long will it take for my skin to become normal ?? Kindly help Iam an ENT specialist myself !
