Will this red mark on my upper right cheek left from a 20% glycolic peel be gone and be back to normal? (Photo)

Thank you for your question. Doing peels at home is never recommended, products like these should be applied by a liscensed professional. I would recommend discontiuing the use of this product, keep your face protected with sunscreen and avoid direct sun exposure. You can use Aquaphor on the burned area until it heals (do not peel skin off as it is healing). It should go back to normal if you are careful and gentle with your skin, it may take a few month before it does. Best Wishes,Pablo Prichard
