We typically recommend a series of 3 treatments spaced 1 month apart. Each treatment builds on itself.  You will continue to see improvement for a few months after the 3rd treatment. If patients take care of their skin by using sunscreen and keeping up the results with topical retinoids, the effects of the treatment can be extended. Often we will recommend coming in for a maintenance treatment once a year for touch-up treatments. We are constantly aging, so with any type of anti-aging treatment there will be maintenance required to keep up the results.
