Photodynamic Therapy For Acne
Using Light Therapy to Cure Acne
PDT for acne is a two step procedure that has amazing results in controlling cystic acne and preventing scar formation. First, a light absorbing agent is applied to the skin and left to penetrate for about an hour. Next, any residual substance that did not absorb into the skin is removed, and the skin is exposed to a special light. The light is attracted to the areas where the light-absorbing agent penetrated; and kills the bacteria in those areas. A slight sense of stinging may be felt when the light is shone on the skin. PDT will cause increased sensitivity to the sun for about two days; so extra care must be taken after PDT to avoid the sun. PDT usually requires two to three treatments, each session two weeks apart.
