Das R.K. et al. - At-Home LED Photobiomodulation and Facial Rejuvenation: A Systematic Review

This systematic review of 8 studies (365 participants) reports that at-home LED photobiomodulation is associated with improvements in facial wrinkles, skin texture, and elasticity. Adverse effects are rare and transient, but protocols vary widely, and no quantitative synthesis is provided.
What this study measured
LED devices used at home for facial rejuvenation are becoming increasingly popular, even though evidence regarding their effectiveness and safety remains scattered. Rishub Das and his colleagues in the Department of Plastic Surgery at Vanderbilt University Medical Center have therefore compiled the available data.
The search was conducted in MEDLINE/PubMed, in accordance with the PRISMA guidelines. Randomized trials, prospective cohort studies, and split-face studies evaluating LED devices for home use were included. In-office devices, laser systems, and preclinical models were excluded. The authors extracted data on wavelengths, treatment regimens, clinical outcomes, and adverse effects, along with objective and subjective measures of facial aging.
Key Findings
Eight studies, involving 365 participants, met the inclusion criteria. The summary does not provide pooled figures, but describes the following trends.
- Wavelengths: from 440 to 1,072 nm, with red and near-infrared light being the most commonly used
- Clinical signs: statistically significant improvements in wrinkles, skin texture, elasticity, and periorbital wrinkles
- Patient satisfaction: high levels
- Side effects: infrequent, mild, and temporary
How photobiomodulation works for this indication
The abstract does not describe a specific mechanism. Generally speaking, it is proposed that red and near-infrared light, when absorbed by the mitochondria in skin cells, may stimulate their activity, particularly that of fibroblasts, which produce collagen. This hypothesis is not tested in the study, which is limited to describing clinical results and skin measurements.
Limits You Should Know
The authors highlight several limitations. Treatment protocols vary widely from one study to another. Comparative data between devices are limited, and skin types of various phototypes are underrepresented in the studies.
The review is based on a single database, PubMed, and does not include a meta-analysis; therefore, no overall effect size is estimated. The range of 440 to 1,072 nm also includes blue wavelengths, whose effects differ from those of red and near-infrared light, on which most of the favorable findings are focused. The authors call for larger, standardized, and comparative trials.
What This Means in Practice
For anyone considering a home LED device, this review indicates that red and near-infrared light has been associated with visible improvements in skin condition in small studies, with a generally reassuring safety profile. It does not provide guidance on selecting a specific device, dose, or frequency.
If you have a skin condition, are undergoing photosensitizing treatment, or have any concerns, it is best to consult a dermatologist or healthcare professional. Photobiomodulation is not a substitute for prescribed treatment.
Frequently Asked Questions
Do at-home LED treatments reduce wrinkles?
In this review of 8 studies, at-home LED photobiomodulation is associated with statistically significant improvements in wrinkles, skin texture, and skin elasticity. No overall effect size is provided.
Are at-home LED lights safe for the face?
The reported adverse effects are infrequent, mild, and transient. The authors note, however, that skin types other than those included in the studies are underrepresented, which limits the scope of this finding.
Which wavelength is used most often?
The studies cover wavelengths ranging from 440 to 1,072 nm, with a majority of red and near-infrared light. The authors do not specify an optimal protocol.
