What is Low Level Light Therapy? Is it Safe?

Low Level Light Therapy or LLLT is a body slimming technology that is non-invasive and has gained popularity in the most recent years. Practitioners have found it to be an effective treatment for reduction around areas like the waist, hips, and thighs.

The technology uses low level laser energy, from red or green light to target and remove fat cells, leading to a slimmer, more toned appearance. The laser energy penetrates the skin and targets fat cells. The laser energy interrupts the cell membrane of the fat cells, causing them to release the stored fatty acids and glycerol into the surrounding tissues. These fatty acids and glycerol are then metabolized by the body and excreted through the lymphatic system which could lead to a reduction in inches.

When the adipose cells absorb light energy, it activates a sequence of reactions. The mitochondria become more active, leading to an increase in the production of ATP (adenosine triphosphate), which is necessary for cellular energy. As a result of heightened cellular activity, fat cells begin to release their stored triglycerides into the bloodstream, which are then metabolized and used as an energy source by the body.

Over time, repeated LLLT sessions can lead to a reduction in the size of fat cells, contributing to a slimmer and more contoured appearance in the treated area.

LLLT uses an FDA cleared device and is considered safe when performed by a trained and licensed professional. The low-level laser energy used in the procedure does not heat or damage the skin, and there are no known long-term side effects. However, with any therapy or procedure, there are some risks and potential side effects associated with LLLT. The potential side effects may include redness, swelling, and bruising in the treated area, as well as temporary changes in skin sensation. It is important to discuss any concerns or medical conditions with your provider before undergoing any body contouring therapy.

How Long Before I See Results?

The length of time and frequency of LLLT sessions may vary depending on the individual and the treatment area. Usually, a course of LLLT typically consists of 5-15 sessions with visible results over the course of 2-6 weeks.

The primary benefit of LLLT is a fat reduction and body contouring. In addition to fat reduction, LLLT may improve the appearance of cellulite and tighten and firm the skin in the treated area. It is a painless alternative to surgical interventions such as liposuction. LLLT does not require any anesthesia, or incisions. There is no lengthy recovery period. Treatments are typically quick and require no recovery time, allowing clients to return to their normal routines immediately. LLLT sessions can be tailored to address specific areas of concern and achieve individual body contouring goals.


LLLT is emerging as a promising, non-invasive option for those looking to reduce unwanted fat and achieve a slimmer, more sculpted appearance. As the demand for non-surgical cosmetic procedures continues to grow, LLLT is gaining recognition for its effectiveness in fat reduction and body contouring. If you’re considering a non-invasive approach to enhance your body, consulting with a qualified practitioner can help you discover the possibilities and determine if LLLT is the right choice for you.
