A single IPL treatment is not sufficient to provide ample rejuvenation of your skin and elimination of long-standing sun damage. Therefore, for optimal results it is recommended to have more than one IPL treatment. In other words, as you have progressive IPL treatments, the pigmented areas of melanin will begin making their way to the top layers of your skin, and eventually reaching the surface to flake off. Because many of these cells are located in the deeper layer of your skin you will need multiple treatments before your pigmented cells can reach the surface and become permanently eliminated. Therefore, IPL photofacial treatments can be spaced approximately 4 – 6 weeks apart to allow natural cell turnover and provide enough time for your skin to recover from previous treatments.
