Multi-Wavelength LED Photobiomodulation Improves Photoaged Skin of the Face, Neck, and Décolleté

Photoageing of the face, neck, and décolleté is driven predominantly by chronic ultraviolet exposure and can cause substantial aesthetic and psychosocial burden. Although red and near-infrared photobiomodulation (PBM) may improve wrinkles and skin quality, the effects of simultaneous 633, 830, 1072 nm light delivered by at-home light-emitting diode (LED) devices across these regions have not been evaluated in women. This study assessed biophysical, clinical and participant-reported effects of multi-wavelength PBM. Thirty-three women aged 41–55 years with dry, photoaged skin were enrolled. Thirty-one completed 56 days of treatment. Participants used face, neck and décolleté masks containing Veritace®-tested LEDs for 10 min per session, five times weekly. Endpoints included skin texture, elasticity, firmness, hydration, barrier function, colour, and erythema. A dermatologist graded fine lines and wrinkles at baseline and day 56, and participants completed satisfaction questionnaires. By day 56, significant improvements were observed in skin texture, elasticity, hydration, barrier function, erythema, and colourimetric indices. Dermatologist-assessed fine lines and wrinkles decreased significantly across all sites. Participants reported improved hydration, smoothness, radiance, firmness, and overall appearance. At-home mask use was associated with improvements in multiple measures of photoaged skin, but the study is limited by absence of a control group.
