Time to heal.: Obviously not something to try again. Damaged skin has to heal now. Will take some time.keep it clean. Vaseline if needed to keep the skin from adhering to clothing. Topical hydrocortisone only for a couple of days might reduce some of the inflammation . Don't use this any longer. Watch for infection. It may be hard to know if the reaction is due to skin reaction or an infection. Go see a doctor i
