In the ever-evolving world of aesthetic medicine, LED light therapy has emerged as a powerful, non-invasive tool for skin rejuvenation and wound healing.


At The Clinic by La Ross, we use the Dermalux LED TriWave MD, renowned for its advanced technology and clinically proven results.


But what exactly makes LED therapy so effective?


What Is LED Light Therapy?


LED (Light Emitting Diode) therapy involves the use of specific wavelengths of light to stimulate skin cells, improve circulation, and promote healing. Unlike lasers or intense pulsed light (IPL), LED doesn’t use heat or cause trauma to the skin, making it ideal for all skin types even sensitive and inflamed skin.


How Does It Work?


The Dermalux device delivers three clinically proven wavelengths of light:


  • Blue Light (415nm) – Targets acne causing bacteria, reduces breakouts, and soothes inflammation.


  • Red Light (633nm) – Stimulates collagen and elastin production, improves circulation, and reduces fine lines.


  • Near-Infrared Light (830nm) – Accelerates wound healing, reduces pigmentation, and soothes redness and irritation.


These wavelengths can be used individually or combined in Tri-Wave mode for maximum benefits.


Clinical Research


Numerous studies support the efficacy of LED light therapy. Research published in the Journal of Clinical and Aesthetic Dermatology has shown significant improvements in skin texture, clarity, and fine lines with consistent LED use (Goldberg, 2014).


The Dermalux system itself is CE-certified and medically approved, offering a level of safety and effectiveness unmatched by many other systems on the market (Aesthetic Technology Ltd, 2023).


Why Patients Love It


  • Painless and relaxing

  • No downtime

  • Suitable post-treatment/surgical procedure (after injectables, microneedling, surgery or peels)

  • Visible results within a few sessions


LED as Part of a Holistic Aesthetic Plan


At The Clinic by La Ross, we incorporate LED light therapy post-procedure to enhance healing and reduce inflammation. It’s also offered as a stand-alone treatment or part of a bespoke skin program.


If you're looking to enhance your skin’s natural glow, reduce signs of ageing, manage breakouts and manage would healing, LED light therapy is a clinically proven, results driven solution and with Dermalux, you're experiencing the very best in LED technology!
