Technology has had a huge impact in cosmetic dermatology. Dr. Anna Magee with Martha Jefferson Hospital explains one of the most in-demand treatments as being photodynamic therapy. This treatment uses a light sensitizing chemical that we apply to the skin and it’s followed by light therapy with laser or blue print. It is effective at treating precancerous lesions, some skin cancers and it’s also used to treat sun damaged skin. Also, patients that use Fraxl cream say that instead of their recovery time involving a month or more, it only takes days to recover. This treatment is mostly used to get rid of age spots, brown spots, acne scars and crows feet.
