Laser treatment may reverse sun damaged skin

Ann Arbor, Mich.

- Photodynamic therapy could improve the appearance of sun damaged skin, according to a University of Michigan study.

The study looked at 10 men and 15 women between the ages of 54 and 83, who had sun damaged skin. The researchers found the therapy, which combined Levulan with pulsed dye laser treatments, increased the production of collagen and promoted a thickening of the top layer of skin. The team found that collagen production was twice as great with Levulan and the laser treatment compared with the laser treatment alone, paktribune reports.
