How do chemical peels work? Crystal always want her clients to receive the best treatment for their desired goals and will work with you to develop a treatment plan that is comfortable for you. Chemical peels at Crystal Skin Care contain individualized exfoliating solutions that may include glycolic, salicylic, trichloroacetic, or lactic acids. This specialized solution is applied to the skin which causes the oldest layer of skin to peel and flake off. As your skin recovers from the chemical peel treatment it will start to repair itself revealing a clearer and smoother complexion.
