It all depends on the depth of the peel and your concern. Usually, you can expect once every two to four weeks, with lighter peels being more frequent.
Once the desired result has been achieved with a series of glycolic peels a maintenance peel every 2-3 months is recommended.If you are having stronger peels such as the VI peel, usually 1-2 treatments a year is ideal for maintaining your outcome. Maintaining your skin with your home regimen is important as well. Using a medical grade skin care line and SPF 30 will help to not only maintain your results but enhance them as well.
Chemical peels refresh the skin and get rid of sun damage so I recommend at least a yearly peel for everyone. Light chemical peels should be done every 3 months @ $250 each and medium peels done once a year at $500 each.
