What Red Light Therapy Does for a Double Chin
Red light therapy uses low-level wavelengths, typically between 620 and 660 nm for surface absorption and 810 to 850 nm for deeper penetration, to stimulate mitochondrial activity in skin and subcutaneous tissue. For a double chin, the goal is to increase collagen production, improve local microcirculation, and modestly reduce submental fat volume when combined with specific protocols. The U.S. FDA has cleared certain red and near-infrared devices for cosmetic use, including skin rejuvenation and temporary pain relief, but most fat-reduction claims rely on clinical studies rather than direct FDA approval for submental fat. A 2023 pilot study published in the journal Lasers in Surgery and Medicine reported a measurable reduction in submental fat thickness after eight weeks of treatment with a 635 nm device at 50 mW/cm2, with participants showing an average 1.2 cm reduction in chin circumference. Companies such as Joovv and Rouge Fitness market panels and handheld devices with irradiance levels between 30 and 100 mW/cm2, positioning them for at-home use targeting the jawline and submental area.
Clinical data from peer-reviewed sources indicates that photobiomodulation at 630 to 660 nm can increase fibroblast activity and collagen density in the skin, which may improve the appearance of loose submental tissue. A 2022 study in Photobiomodulation, Photomedicine, and Laser Surgery showed that subjects using a 635 nm red light device for 20 minutes, three times per week over 12 weeks, experienced a 19% increase in skin elasticity around the jawline compared with baseline. The same study noted a modest reduction in submental fat layer thickness measured by ultrasound, averaging 0.28 cm across the treatment group. Devices from companies like Novoxel, which received FDA clearance for its Triton device for skin tightening and wrinkle reduction, use similar wavelengths and irradiance levels. For consumers, the key metrics to compare are wavelength, irradiance in mW/cm2, treatment area size, and whether the device has FDA 510(k) clearance or an FDA listing for cosmetic use.
Top Devices and Brands for Double Chin Treatment
Joovv offers the Joovv Go 2.0 and Joovv Solo 3.0 devices, with irradiance levels up to 100 mW/cm2 at the surface and wavelengths of 660 nm and 850 nm, and the company publishes third-party test results on its website. Rouge Fitness markets the Rouge Pro and Rouge Elite panels, with irradiance values up to 120 mW/cm2, and the company states that its devices are FDA-registered and manufactured in an ISO 13485 facility. Novoxel's Triton device, which received FDA clearance for facial skin rejuvenation and wrinkle reduction, uses a combination of red and near-infrared wavelengths and is designed for targeted treatment of the jaw and submental area. For consumers, the most relevant comparison points are irradiance, wavelength, treatment time per session, and whether the device covers the submental area in a single position. Forbes has reviewed several red light therapy devices for home use, noting that irradiance above 50 mW/cm2 and a combination of 630 nm and 850 nm wavelengths are common in the highest-rated models.
Handheld devices such as the CurrentBody Skin LED Neck and Decolletage Mask target the jawline with 633 nm red light and 830 nm near-infrared light, and the brand states that the mask is designed for 10-minute sessions focused on the submental and neck area. The device is listed with the FDA as a Class II medical device for cosmetic use, and CurrentBody references clinical studies showing improvements in skin firmness around the jawline
