I recently gave a chocolate peel containing salicylic, lactic, glycolic & kojic acid to a friend, she now has discoloration under her nose & above upper lip (red/purple) does this mean that she received a chemical burn in this area? What are the signs of a chemical burn? Will it scar her face if so? I have no picture sorry - just talked with her on the phone yesterday. This peel is not anywhere close to TCA strength.
