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, I’m on month two of the Trifecta products. So far I LOVE it!
Do I need to be using any other moisturizers before applying my SPF and makeup or is the Illuminate product enough? Also, I have hooded eyelids, is there any product you recommend to help with this besides surgery?

Hi Ali —Thanks for your comment! We’re so happy to hear you’re loving the Trifecta. Illuminate offers good hydration for most, so no extra moisturizer is needed unless your skin feels dry. If so, you can layer a richer cream like our Enrich Moisture Barrier Balm or another you already use. For hooded lids, topical products can support skin quality but won’t change structure. The Trifecta can be used around the eyes and may help improve tone and firmness over time (just be sure to avoid the eyes themselves 😉).

Hi Michael—Thanks for your comment! We love EltaMd Sunscreen <https://karammdskin.com/collections/products/products/eltamd-uv-sheer-broad-spectrum-spf-50-sheer-sunscreen> if you are located within the US. If you aren’t or have another preference, these are the things we believe are essential in a sunscreen: 1. Must be designated as Broad Spectrum (meaning it blocks both UVA and UBE light). 2. Presence of a physical blocker such as Zinc or Titanium Oxide (in the 6 or 7% range) 3. Waterproof or water resistant if you’re going to be exercising or swimming, etc.

Hello. Will Trifecta work on lightening melasma? Or do I need to incorporate additional products? If so, what would you advise? Also, if I were to do microneedling in conjunction with Trifecta, is that something that will also help with my melasma? Or can microneedling (PRF) possibly make the melasma worse?

Hi Joanne—Thanks for your comment! The short answer is, yes. With consistency the Trifecta can help with Melasma over time. The Trifecta system is clinically backed and includes powerful ingredients that support a more even skin tone like retinol, vitamin C, and botanical lighteners such as daisy flower and licorice root extract. That being said, results with pigmentation take time. Consistency is key, and combining the Trifecta with daily sun protection is one of the most effective ways to gradually address your melasma and keep it from getting worse.

Hi Ghazala—Thank you for your question! Thank you for your message! While we don’t have a specific recommendation for a red light cap, we’re happy to offer some guidance on what to look for when choosing a quality device. We recommend looking for caps that have been independently tested, use wavelengths in the therapeutic range of 630-680 nm, and offer sufficient power output (measured in mW/cm²) to ensure effective light penetration to the scalp. Additionally, it’s important to choose a cap that is FDA-cleared or has other certifications indicating safety and quality.
