Did you know that 1 in 3 adults (30.7%) is overweight, and over 2 in 5 adults (42.4%) have obesity[1]. To reduce excess fat and regain their self-esteem, people now look for non-invasive methods. One popular approach is red light therapy for weight loss that’s now available in most clinics, beauty centers, and homes.
But what exactly is red light therapy? Does it help you lose weight, and who can benefit from it? Let’s discuss!
Basic Concepts of Red Light Therapy
When it comes to quickly and easily contouring your body and reducing fat, red light therapy emerges as a great choice. Here’s an overview of its core definition and how it penetrates your skin tissue:
Definition of Red Light Therapy
Red light therapy for weight loss, or low-level laser therapy, is a non-invasive procedure that claims to remove fat cells without surgery. It uses a low-irradiance laser emitting red, blue, and infrared light, around 1 to 2 inches into your skin.
During the procedure, a practitioner will use a laser to direct light into your skin, penetrating a few inches below the surface. It targets the fat that sits right below your skin, known as subcutaneous fat. The fat cells get blasted and are removed from the body right away.
This therapy was first used by Endre Mester in 1967, who applied it to mice and then to humans. These days, it can be done by a dermatologist, plastic surgeon, or weight-loss specialist, but some professional med spas also offer it.
Penetration of Red Light to the Skin Tissue
When it comes to red light penetration, it’s about how far the light travels into tissue while remaining biologically active. Know that as light goes into your body, it gets scattered and absorbed by different molecules. Let’s look at the penetration depth of red light therapy for weight loss and the factors that affect it:
- 633 nm wavelength reaches 1.8 mm in the tissue
- 660 nm wavelength reaches up to 10 mm, subject to skin condition
- 850 nm wavelength of near-infrared light can reach up to 40 mm, as mentioned in many studies
The exact penetration of red light therapy for weight loss varies depending on your tissue composition, the light wavelength, and the power or intensity.
Balanced Review of Current Scientific Findings
Red light therapy for weight loss has gained immense popularity as well as effectiveness, which has become the first choice for many people. To better understand this approach, here are evidence-based benefits of this approach along with potential limitations:
Studies That Suggest Potential Benefits
There are many benefits of red light therapy, from body fat reduction to improved metabolism and easy accessibility.
1. Reduction in Body Circumference
One of the major benefits of red light therapy for weight loss is that it helps reduce body circumference. The light penetrates the skin, stimulating mitochondria to temporarily open pores in fat cells, releasing stored fatty acids and glycerols.
This then reduces the size of the cells around your hips, waist, and arms, creating a slimmer, more contoured appearance. A double-blind, randomized, placebo-controlled study published in Lasers in Surgery and Medicine reported that 65 adults with BMI 25–30 kg/m² received three LLT treatments over two weeks (six sessions)[2].
After the sessions, the active treatment group showed a mean total circumference reduction of about 3.51 inches across the measured sites.
2. Improvement in Metabolic Markers
Many studies suggest that red light therapy also improves metabolic markers, which indirectly help with weight loss. For instance, RLT can reduce fasting glucose and improve insulin sensitivity.
It also lowers systemic inflammatory markers such as C-reactive protein (CRP) and Interleukin-6 (IL-6), which are usually elevated in obese people and can impede fat loss. Another systematic review included adults in the obese category with a BMI≥30 kg/m².
They were given red light therapy and other comparators like exercise, dietary interventions, or sham Photobiomodulation (PBM). However, RLT or PBM was associated with lower BMI and improvements in CRP, total cholesterol, and HOMA-IR[3].
Compared with weight loss medications and traditional liposuction, red light therapy is generally considered a safer option because it is non-invasive, painless, and typically involves no downtime.
Realistic Expectations About the Groups Who Can Benefit from Red Light Therapy for Weight Loss
Here’s an overview of the groups that can actually benefit from red light therapy for weight loss:
- Individuals Seeking Minor Body Contouring: Ideal for those who have recently lost weight and are dealing with loose skin. RLT will tighten and restore your skin’s elasticity by stimulating collagen production, so you feel confident in your skin.
- Groups Looking for Non-Invasive Cosmetic Treatments: Traditional treatments like liposuction are painful and may not be suitable for people who seek comfort. RLT is non-invasive, which means you don’t feel any pain and can smoothly have fat removed without any downtime.
