At-Home Red Light Devices Linked To Facial Skin Gains Across Eight Studies

A new systematic review pools eight studies on at-home LED facial devices, giving Dr. Axe readers a clearer read on a popular at-home therapy.

A systematic review published October 14, 2026 in Aesthetic Plastic Surgery examined eight studies and 365 participants using at-home LED light therapy devices for facial rejuvenation, finding consistent improvements in skin appearance with infrequent, mild side effects.

365people, 8 studies

440–1072nm tested

Researchers reviewed eight clinical studies covering 365 people who used at-home light-emitting diode, or LED, devices on their faces, following PRISMA systematic review guidelines. The studies included randomized controlled trials and prospective designs, including split-face comparisons where one side of a person's face served as the untreated comparison. Devices tested wavelengths ranging from 440 to 1072 nanometers, with red and near-infrared light used most often. Across the eight studies, at-home LED therapy was linked to measurable improvements in wrinkles, skin texture, elasticity and periorbital rhytids, the fine lines around the eyes, along with high patient-reported satisfaction. Side effects were infrequent, mild and temporary, though the specific adverse events and their rates were not detailed in the abstract. The authors did not report one pooled percentage or absolute change; the review summarizes a pattern across the eight studies rather than a single combined number.

Red and near-infrared light is absorbed by skin cells and can support their internal energy production, a process linked to collagen output and tissue repair. The consistency of that pattern across eight independent studies, rather than one large trial, strengthens the case for a therapy already sold without a prescription.

Treatment regimens, including duration and frequency, varied considerably from study to study, and the review notes limited comparative data against other treatments and underrepresentation of diverse skin phenotypes. This is a review of existing studies, not a new standardized trial, so it points to a direction rather than one definitive dose or protocol.

Dr. Axe’s Take

Red and near-infrared light is one of the more underused tools in skin care, and this review lines up with a consistent, low-risk signal across real studies. If I were shopping for an at-home device, I would pick one that specifically emits red or near-infrared wavelengths, since those showed up most often here, and I would use it consistently rather than sporadically, since skin remodeling takes weeks, not days. Keep expectations realistic: this is a modest, cumulative tool for texture and fine lines, not a replacement for sleep, hydration and sun protection.
