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.

Hi Jenny—Thank you for your comment! We’re so glad you love the KaramMD products and we’ll take your suggestion about body wash into consideration for the future! We don’t recommend any specific brand of red light device. The most important piece is to find the appropriate wavelength for your needs and make sure the device is FDA approved with an irradiance between 660-800nm (depending on goals of treatment). When you find something that fits, check that it has great reviews and comes from a reputable company.

Is red light therapy OK to use after having had a face and neck lift? Thanks!

KaramMD Skin replied:
Hi Gayle—Yes, red light therapy is generally considered safe after a face and neck lift, but timing is crucial. Red light is known for promoting healing, reducing inflammation, and boosting collagen production, which means red light therapy can enhance recovery and improve results. However, it’s essential to wait until your incisions have fully healed and your surgeon approves it. Starting too soon could interfere with the healing process, so always follow your surgeon’s guidance for the best outcome. Hope that helps!

Hi Carmen—You can find the answer to this, and other Red Light questions on Dr. Karam’s follow-up article "Red Light Therapy: 5 FAQs + The Answers You Need to Know” which you might find interesting. In short, for best results make sure your face in cleansed with Rinse, so there is no residue blocking your skin from the light, and then after you finish your Red Light session follow-up with Quench and Illuminate. There are mixed reviews about whether or not products interfere with the light. While sunscreen, mineral-based make-up, and clothing do not allow the light to pass through, it can depends on the product, and there is always a chance the light could cause irritation with active ingredients depending on the sensitivity of your skin. We say, to be safe, just use red light on freshly cleansed skin so there is not interference with the light and products, and follow with the rest of your routine after.
