The results of a chemical peel vary depending on the peel that you receive. A superficial peel only slightly reduces the signs of aging and skin damage and the results are minimal unless used in cycles, then generally desired results are more achievable. Medium peels are effective in reducing signs of sun damage and fine wrinkles. A deep peel noticeably tightens the skin and eliminates wrinkles and the effects are commonly dramatic. Repeated deep peels are not recommended.
When you have tried other products that are not effective for your skin or what you are looking to accomplish with your skin goals, a chemical peel would be a good place to start as they are much more effective than standard over the counter products. It is always best to start with a lower level 1 peel and apply it for the minimum amount of time before increasing the time on the skin or using it in layers.
