Good morning and thank you for your question! If you are referring to the Perfect Derma Peel by Bella Medical then it would depend on the number of passes performed and the pressure used when the peel was applied. If the peel was applied correctly, meaning it was vigorously rubbed on the skin with a saturated 2x2 gauze pad, then it should have been a medium depth peel. The Perfect Derma is a blend of TCA, Kojic Acid, Retinoic Acid, Phenol, Vitamin C, Salicylic Acid, and Glutathione. It is great for hyperpigmentation, fine lines, and acne, among others. It is great for all skin types and colors. Some patients will end up not "peeling" or "flaking" depending on how well they take care of their skin. Just because you did not peel does not mean the peel did not work. I would follow up with your Esthetician. Best of luck! For more information please feel free to visit our website!
