Mild and medium-strength chemical peels usually require a series of treatment sessions to be effective in the long-term. That said, some people get satisfiable results in just one treatment. Depending on what is being treated, we may recommend repeating the chemical peel process every 4 - 6 weeks, initially, for best results. For example, if you have bad acne scars, you may need a series of treatments scheduled more closely together (we will give our best estimate on this when we see you in person for a consultation). For a general beauty treatment, chemical peels once every 6 months or so may be enough for you. For regular upkeep, the HydraFacial procedure, with mild chemical additives and nutrients, can be done monthly.
