How Does Red Light Therapy Work?
Red Light Therapy, also known as Low-Level Laser Therapy or Photobiomodulation, is a non-invasive treatment that uses specific wavelengths of red or near-infrared light, directly influencing the way cells function. The range of wavelengths typically falls between 630-700 nm, which stimulates and strengthens the mitochondria in the cells to promote healing and reduce inflammation.
Different wavelengths can penetrate the skin at various depths, allowing the therapy to reach different layers of the skin. The visible red light improves the cellular functioning of visible cells, which is why it’s gaining so such traction in skincare, as it tackles numerous issues related to skin health, from sun damage and dry skin, to eczema or psoriasis, scarring and wound healing, acne, wrinkles, etc.
The non-visible light is working to improve functioning of non-visible cells like those found in the blood, organs, tissues, muscles, joints, etc. The treatment has gained traction in both cosmetic and therapeutic sectors, and understanding how red light therapy works can demystify this popular trend and shed light on why there is so much buzz about it in the skincare world.

Is there any “at home” red light systems you could recommend or and or information for study?
Thank you

I don’t consider trying anything new unless Dr. Karam approves of it! I have learned so much through your skin school, thank you!

Is this red light therapy the same type that vendors are selling right now? It fits over the face and emits red light? Can you buy a device to do it? Or, do you have to go to have it done professionally.

Do you use red light therapy on clean skin or after applying Trifecta?
