Combined 633-nm and 830-nm led treatment of photoaging skin.
OBJECTIVE
To evaluate the clinical efficacy and ultrastructural changes in photodamaged skin after combined 633-nm and 830-nm light-emitting diode (LED) treatments.


METHODS
Thirty-six subjects received 9 LED treatments over the course of 5 weeks and were subsequently evaluated for final clinical improvement 12 weeks after treatment. Five subjects were also biopsied to determine the ultrastuctural posttreatment changes in collagen fibers.


RESULTS
A statistically significant improvement in wrinkles was seen after profilometric analysis. The majority of subjects reported improvements in softness, smoothness, and firmness at all time points. Electron microscopic analysis showed evidence of post-LED treatment of thicker collagen fibers.


CONCLUSIONS
633-nm and 830-nm LED treatments play a role in the treatment of photodamaged skin. LED treatments can be used as either a primary or adjunctive treatment modality.
