We want you to achieve the best results with minimal side effects. Before your chemical peel, you can prepare your skin for stress-free exfoliation by avoiding sun exposure and products that tend to irritate the epidermis. Exfoliating ingredients like alpha and beta hydroxy acids should be avoided. Serums and medications like Retin-A should, as well. You also should not undergo other professional treatments, such as laser resurfacing, waxing, or tanning for at least one week before receiving a chemical peel.
