For the best possible results, we recommend 1 to 4 Laser Rejuvenation treatments, additional treatments may be required depending on the density of pigmentation and severity of UV damage on the skin. Improvement may be visible after the first session. Long-lasting results will be achieved with commitment to the use of sunscreen and avoidance of sun exposure. As long as healing from the previous session is completed treatments can take place every 4 to 6 weeks. The average session takes approximately 30 minutes but will vary depending on the size of the area being treated.
