You’ve probably seen the glowing red face masks all over your social feeds. Maybe you’ve wondered if they actually work or if this is just another wellness trend that’ll be forgotten in six months. As a plastic surgeon who has been practicing for over two decades, I can tell you that red light therapy is not new, and the science behind it is worth understanding.
I recently discussed this topic with Rough Draft Atlanta as part of their health and wellness coverage, and as a plastic surgeon who focuses on facial plastics and aesthetics, I want to expand on what I shared there because there’s a lot more to say.
It’s Been Around Longer Than TikTok
Red light therapy, also called photomodulation, has been used by dermatologists and estheticians since the early 2000s. Its roots go back even further. A Hungarian physician discovered in the 1960s that low-level ruby laser light helped wounds heal in laboratory mice. NASA later advanced the research when astronauts found the lights, originally used to grow plants in space, also benefited muscle recovery and cellular repair.
The treatment works by delivering specific wavelengths of light, typically in the 630 to 670 nanometer range, that penetrate below the skin’s surface. At that depth, the light targets the mitochondria, the part of your cells responsible for producing energy. When mitochondria are stimulated this way, they accelerate healing and collagen production. That’s the short version of why it works.
One point of confusion worth clearing up: not all light therapy is the same. Red light typically falls in that 630 to 670 nanometer range, but many devices also use near-infrared light, usually around 810 to 850 nanometers. The difference matters. Near-infrared sits further along the spectrum and penetrates more deeply, reaching muscle and deeper tissue, while visible red works closer to the surface where collagen lives. You’ll also see the treatment referred to as photobiomodulation or low-level laser therapy (LLLT) in clinical literature. Same underlying principle, different names depending on who’s writing about it.
It’s also worth distinguishing red light from blue light, since the two get grouped together and they do very different jobs. Blue light, usually in the 415 nanometer range, targets the bacteria associated with acne. Red and near-infrared are the wavelengths tied to collagen, fine lines, wound healing, and the kind of skin-quality improvements most people are after. Some devices combine both, but if your goal is firmness and texture rather than breakouts, red is the one doing the heavy lifting.
Why I Use It in My Practice
At Artisan, we incorporate red light therapy into recovery protocols following non-surgical facial rejuvenation with lasers, collagen-induction work including the microneedling treatment for skin rejuvenation we offer, and facial surgery. I actually used it myself while recovering from my own facelift, one of the facial rejuvenation surgery options we perform.
Here’s the thing about aesthetic procedures: results matter, but so does the healing process. Patients want to look their best, and that means minimizing the period where skin looks red, irritated, or raw. Red light speeds up that process by supporting tissue repair at the cellular level. It helps patients get through recovery faster and feel better about the results sooner.
Beyond post-procedure recovery, it works well as a standalone treatment for inflammatory skin conditions. Rosacea and psoriasis both respond positively because red light helps reduce inflammation and redness while also supporting collagen and elasticity over time. It’s one of the more versatile tools we have.
At-Home Devices vs. Clinical Treatments
Portable red light devices, including the masks people are using at home, can deliver real benefits. The key is using a quality device with multiple wavelengths for better results. FDA-cleared options are worth the investment if you’re going to commit to regular use.
A few practical notes on getting the most out of an at-home device:
- Use it over hydrating ingredients like hyaluronic acid or a moisturizer, since the wavelengths can actually push those ingredients deeper into the skin.
- Avoid using red light in combination with retinols or exfoliants, as those can create irritation.
- Keep sessions to 20 minutes or less per day.
The American Academy of Dermatology also recommends that people with darker skin tones or conditions like lupus that cause light sensitivity consult with a provider before regular use, as there is some risk of hyperpigmentation.
The Bottom Line
Yes, red light therapy is having a moment right now. But it has clinical backing behind it, and that’s exactly why we use it here. It isn’t a shortcut or a gimmick. It’s a tool that, used correctly, makes a real difference in how skin heals and how it looks over time.
If you’re curious whether red light therapy makes sense as part of your treatment plan, or if you want to learn more about how we incorporate it across our Atlanta plastic surgery procedures, we’d love to talk.
As discussed in Rough Draft Atlanta’s health and wellness column, The Reset, Dr. Alexander recently spoke on the science behind red light therapy and its role in clinical skin care. Read the full feature here.
