In our first light therapy article Shedding "Light" on Non-invasive LED Skin Care Treatments, we provided an overview of Light therapy and how low-level wavelengths of light can potentially treat a variety of skin conditions, improve skin tone, reduce pain, scarring, and even wrinkles.
Red light therapy or low-level light therapy (LLLT) is a non-invasive treatment that also claims to help target and eliminate fat. (2) Today, we will take a closer look at these claims.
Using LLLT is safe, painless, and easy for the average user to apply, but how does it work? Red and infrared light penetrates the skin surface and temporarily alters the permeability of your fat cells; this exposure stimulates cells causing the adipocytes to release triglycerides which can be processed naturally through the lymphatic system, thus resulting in reduced volume and a measurable loss of fat.
The results of this 2016 study confirm the results of previous studies demonstrating the effectiveness of LLLT. Researchers concluded that “1 weekly LLLT treatment for 6 weeks is clinically effective for reducing waist, hip, thigh, and upper abdomen circumference, (1) by 13 cm (about 5 inches) after 6 weeks.” The device in the study used 635nm red laser diodes.
Efficacy for body contouring and spot fat reduction was explored in a 2011 study (2) that found it “safe and showed significant girth loss sustained over repeated treatments and cumulative over 4 weeks of eight treatments”.
Much of the research to date highlights limited fat loss after six or more treatments of red light therapy; this warrants more extensive, longer-term studies.
Did you know that red light therapy has been shown to help curb your appetite?
Red light therapy offers another benefit to those trying to stick with better nutritional choices or a specific diet to help them lose weight. In 2012 researchers looked at the effects of light on leptin and ghrelin. (3). Leptin is a hormone responsible for controlling our appetite and maintaining body weight. It can help to regulate how much energy we burn. Ghrelin is the opposite, it can increase appetite, and the levels can often increase with lack of sleep. This study focused on participants with poor sleep habits. It showed that exposure to red light significantly increased leptin levels while decreasing ghrelin.
How to Maximize Results
Treatments at Home - With the availability of home light therapy products applying the science behind them is not only more accessible but affordable compared to treatment at a clinic. If you can treat yourself on a regular basis, you are more likely to achieve and maintain your results.
Get Moving after your treatment – We explained how exposure to LLLT stimulates cells to release triglycerides, which it is processed naturally through the lymphatic system. Post-exercise or even some basic movement can boost circulation and lymph, helping the effectiveness of this process. If muscle tone or definition is a goal, LLLT might be the perfect complement before your regular workout.
Common Sense Compliments – Reminder that good hydration, proper nourishment, and rest are essential to a healthy lifestyle and can contribute to the effectiveness of these or other treatments you may be considering.
With light therapy tools now available for home use, there is now a surmounting number of anecdotal claims and positive reviews from a growing number of users. Inches lost, skin tone improvements even less muscle tension and stress.
The positive feedback from our own members using the new AllevaRed light therapy belt has been overwhelming, and we are thrilled with the results they are sharing. If you are considering light therapy, this is just one of the four amazing light therapy tools Lifepro has brought to the market.
