Skincare has transcended simple regimes to become a field filled with advanced techniques, devices and procedures. Among these, red light therapy stands out as a noteworthy innovation. I get questions about this all the time on social media, so I wanted to take some time to explain--what is red light therapy, how does it apply to skincare, and should you consider using it?

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.

Interaction with Cells

At the core of red light therapy is its interaction with the skin cells. The red light is absorbed by particular components within the cells, which stimulates a variety of responses. One of the primary reactions is an increase in energy production within the cells. This energy boost helps cells perform their functions more efficiently, helping them to repair, regenerate and increase the cell turnover rate, which in turn leads to healthier cells, faster recovery, improved performance and overall increase in wellness.

Stimulating Natural Processes

What sets red light therapy apart from other treatments is its ability to stimulate the body's natural processes without the need for chemicals or invasive procedures. By enhancing the cells' energy production, red light therapy supports the natural growth and repair mechanisms of the skin. This means the skin can heal itself more quickly and maintain a healthier appearance, all without any artificial interventions. Red light therapy is scientifically and specifically known for its ability to target specific skin concerns, that encourages the skin's natural ability to heal and rejuvenate itself, rather than forcing changes through aggressive means.


A significant aspect of red light therapy's appeal is its reputation for being safe and comfortable. The treatment doesn't rely on harsh chemicals or abrasive techniques, and it usually doesn't cause any discomfort. It's a gentle approach, stimulating your body's natural healing and rejuvenation processes.

The Skin Benefits of Red Light Therapy

Red light therapy has been gaining attention for its wide range of applications in skincare. From tackling wrinkles to soothing acne, it has become a sought-after treatment. Its ability to target a broad range of concerns makes it a unique addition to the skincare world.

Wrinkles and Signs of Aging

Who doesn’t want to keep their skin looking youthful? Red light therapy may be an answer. It helps the skin produce more collagen, a vital component that keeps the skin smooth and firm. More collagen leads to reduced appearance of wrinkles and fine lines, giving the skin a fresher and younger look. It’s like encouraging the skin to turn back time, working on those areas that show age the most.

Acne Problems

Acne is a stubborn problem for many, but red light therapy can offer relief. By reducing the redness and swelling associated with acne and increasing blood flow to affected areas, it promotes quicker healing. This means those troublesome spots can clear up more quickly, leaving behind smoother, clearer skin. It's not an instant fix, but it's a gentle way to help the skin heal itself.

Healing Cuts, Burns, Rashes & Scars

The skin's natural ability to heal can be a slow process. Red light therapy speeds it up by increasing cell turnover rate, which helps the body create new, healthy skin cells more quickly. This can be particularly helpful for reducing the appearance of scars or aiding in the healing process of cuts and burns. It's also helpful when clearing up skin disorders like eczema, psoriasis as it also helps to calm inflammation. It’s like giving your skin a helping hand, guiding it to heal and renew itself faster.

Uneven Skin Tone and Dark Spots

Uneven skin tone or dark spots can be frustrating, but red light therapy may offer a solution. It works on the darker parts of the skin, helping them blend better with the rest of the complexion. It’s a gentle approach to balancing out the skin color, making the complexion more even and radiant.

Dry and Flaky Skin

Dry or flaky skin is more than just an annoyance; it can be uncomfortable. Red light therapy might be the soothing solution needed. By helping the skin retain moisture better, it can leave it feeling softer, more hydrated, and more comfortable. It's a kind and natural approach to helping the skin stay moist and nourished.

To Use? Or Not To Use?

Red Light Therapy brings an exciting addition to the skincare world, providing a non-invasive, low-risk method to enhance skin appearance and heal various conditions, as it encourages the skin to heal and rejuvenate itself. Its scientific backing adds credibility, but individual experiences may differ, and it might not be a fit for everyone. Consulting with a skincare professional is advisable if you are considering this treatment, as they can ensure it aligns with your specific needs and goals. Red light theory for skincare holds great promise, but thoughtful consideration and professional guidance remain essential for achieving the desired results.

Red Light in Tandem with Trifecta

Red Light Therapy undoubtedly marks an exciting addition to the skincare world, offering a natural, scientifically-backed means to enhance skin appearance and facilitate healing through the body's inherent restorative processes. Its ability to encourage the skin's self-healing and rejuvenation is compelling, as it spans such a vast range of concerns and applications. And the good news is, red light therapy is accessible, with many at home devices you can incorporate into your skincare routine. However, it's imperative to remember that while red light therapy devices hold promise, they are not a panacea. The key to unlocking their full potential lies in complementing them with a consistent, comprehensive skincare routine working in tandem.


The Trifecta, used alongside red light therapy, serves as a well-rounded strategy for optimizing skin appearance, texture, and longevity, and will ultimately help you to achieve and maintain healthy, radiant skin. Combining high-quality skincare ingredients with innovative technology like red light therapy, they will help to enhance each other's benefits, leading to a more comprehensive approach to skin health. Maintaining healthy skin through consistent, daily skincare routines and sun protection ensures that the results achieved with red light therapy are preserved and prolonged.

    Hi Susan,
    Trifecta covers all of your daily skincare needs. If you are not already religious with a retinol, the Trifecta is perfect as a stand alone trio. While there won’t be any need for another product, you can continue using a retinol if you’d like to.

    Hi Karla,

    Hi Susan,

    Red light therapy should be used on cleansed skin, before any serums or moisturizers are added. With Trifecta, you would do it after cleansing with Rinse and follow with Quench and Illuminate.

    There are many red light therapy machines out there and Dr. Karam doesn’t have a specific one he recommends. Generally they are reasonable additions to a good skin care routine and we suggest you research your options to find the right one for you.

    Can I continue to incorporate retinoids with Trifecta skincare?
