I had a TCA chemical peel 8 days ago and was prescribed Valacylovir HCL to prevent any herpes. I developed large bright red raised areas that sting, itch, and really hurt on my chest, hands, and forearms, but not on my face that had a higher % (35) concentration applied. My doctor thought I had a bad reaction to the petroleum jelly coating, could it be an allergic reaction to the Valacylovir HCL?
