Laser skin rejuvenation may involve the use of intense pulsed light (IPL), photodynamic therapy (PDT) or ablative laser resurfacing to reduce the signs of aging and improve the overall appearance of the skin. Laser treatments stimulate collagen production for improved aesthetic results. Patients often need several sessions to achieve their desired results, but this treatment can completely remove age spots and other unwanted spots on the skin. It is safer and less invasive than traditional resurfacing procedures.
