The chemical applied to the skin varies, depending on the extent of skin damage. Light to medium chemical peels are advisable for people who have age spots and pigment abnormalities or those suffering from the early stages of photo-aging.Derma Youth Pro Cosmetic surgeons normally use either alpha-hydroxy (glycolic, lactic or fruit acids) or trichloroacetic (TCA) acids for the said procedure. Phenol peels, on the other hand, are recommended for severely damaged skin.While both TCA and AHA can be used to treat light to moderately damaged skin, the former proves to be more effective in providing definite results. Dr. Mitchell E. Blum, a recognized cosmetic surgeon who has been practicing for more than 25 years, provides a deeper, more thorough peel, as opposed to AHA, which may require several applications before results can be achieved. He also states that a TCA skin peel mimics the results of a Phenol peel, in that it penetrates the deeper layers of the skin, but provides a shorter recovery period. TCA peel is also quite affordable, and medical grade kits for home use can be found online.However, Dr. Blum advises the use of tretinoin (preferably Retin-A), glycolic acid and other bleaching agents at least four to six weeks prior to undergoing the procedure to prepare the skin for the chemical peel. This is because tretinoin stimulates the skin to heal faster while glycolic acid enhances the effect of the tretinoin.
