Use of Nonthermal Blue (405- to 420-nm) and Near-Infrared Light (850- to 900-nm) Dual-Wavelength System in Combination with Glycolic Acid Peels and Topical Vitamin C for Skin Photorejuvenation

Abstract

A major cause of skin aging is a chronic microinflammation created by environmental conditions and ultraviolet exposures. The hand-free application on the skin of a new intense light combining a narrowband blue-light (405- to 420-nm) antiinflammatory emission and a near-infrared (850- to 890-nm) emission inducing self-defense mechanisms provides a new component to photorejuvenation and antiaging treatment protocols.

An innovative skin rejuvenation schedule is presented in this study. It includes skin exposure to the light, with concomitant glycolic peels and daily vitamin C cream regimen for group A and only topical vitamin C cream and glycolic peels for control group B.

Results show a significant improvement on pore size, rhytids, and radiance in group A. Conversely no improvement is noticed in group B except for a brief increase of skin radiance. Mechanisms of action of that specific light source are discussed.

The exposure to this device can clinically enhance conventional antiaging protocols in skin rejuvenation.
