How LED Light Can Improve Scarring

• 14 March 2024

Scars emerge as a result of the body healing substantial wounds, characterised by fibrous tissue that is thicker and tougher than the surrounding skin. Often, these scars can be aesthetically displeasing. LED (light-emitting diode) light therapy can assist in scar treatment, breaking down, shrinking and minimising their appearance by activating the body's natural skin healing mechanisms.


Initiating skin healing

The most effective method for stimulating skin healing involves the use of red and near-infrared light at precise wavelengths. Near-infrared (830nm) light activates the 'wound healing cells' in the skin up to 4cm below the surface, while red (633nm) encourages the production of new collagen and elastin fibroblasts. When used together, they enhance blood circulation to help deliver oxygen and nutrients to scar-affected areas. As the most common wavelengths administered inside a clinic, you can now access this same technology from home with portable, wearable and hands free devices.

How to prevent scarring

Whether you're looking to reduce acne scarring, general scar reduction or a smooth recovery from surgery—cosmetic or otherwise—red LED light therapy may be the key to scar prevention.

Red light therapy is widely recognised by plastic surgeons, dermatologists and skin experts as a preventative practice against the formation of scar tissue. “Overall, red light therapy may be a beneficial treatment for helping surgery patients,” says Chicago plastic surgeon, Dr. Anil Shah, MD, FACS,. “It can reduce swelling and inflammation, accelerate healing, reduce pain and improve the appearance of scarring.”

One clinical study in particular shows that red LED light therapy can be safely used in the early postoperative period, and may reduce post-surgical scarring. 

And it’s not just plastic surgeons who recommend this technology. Australian Skin Expert and Chanel facialist, Melanie Grant, uses red LED light therapy on her celebrity clients—including Hailey Bieber, Kim Kardashian, Victoria Beckham and Rosie Huntington-Whitetely. “I’ve worked with LED light therapy for years, and though I’m well-versed in the clinically proven benefits, I’m constantly surprised at the true and palpable results this non-invasive technology delivers.”
