Light Emitting Diode (LED) for the Treatment of Wrinkles

Non-ablative Light Source for the Treatment of Rhytides (Wrinkles)

The purpose of this study was to determine whether light emitting diode (LED) therapy can improve skin appearance of human subjects with aged/photoaged skin. A reduction in rhytid depth as well as in skin surface roughness and in the degree of elastosis after LED treatments was expected.

Inclusion Criteria:

• subjects with aged/photodamaged skin

Exclusion Criteria:

• Subjects were not allowed to participate in this study if they were taking cortisone (Prednisone), anticoagulant therapy, or any drug known to increase photosensitivity. In addition, during the 12 months preceding the study, subjects were required not to have used isotretinoin (Accutane), or applied topical steroids to the site to be treated. Moreover, previous laser or topical medication at the to-be-treated site was not permitted.
