What Red Light Therapy Can Do for Aging Face?

Red light therapy (RLT) has been gaining attention for its potential wellness benefits. From enhancing skin health to alleviating pain, this innovative therapy is making waves in the healthcare community. By targeting the face, this therapy can help reduce signs of aging and improve skin texture. Many people incorporate cosmetic services like red light therapy into their skincare routine for its rejuvenating effects. "Red Light Therapy is known for its ability to improve skin tone, reduce wrinkles and decrease the appearance of scars and blemishes. It promotes collagen production, which can lead to firmer, more youthful-looking skin," says Kaylee Fox, Medical Skin Care Technician, Gundersen Health System.

Red light therapy is an innovative treatment that’s gaining popularity as both an in-office procedure and at-home skin care solution. Red light therapy has a host of benefits for the skin, including the ability to gradually lessen the appearance of fine lines and wrinkles. Red light therapy, also known as low-level light therapy (LLLT) or LED light therapy, leverages light-emitting diodes (LEDs) to deliver specific, controlled wavelengths of red and near-infrared light deep into the skin’s layers, a process called photobiomodulation. The light energy is absorbed by cellular mitochondria, stimulating the production of adenosine triphosphate (ATP), the energy currency of the cell.

The light therapy works by helping your body produce more of the proteins that give your skin its bounce and firmness. Red light stimulates "cells in the dermis called fibroblasts," Dr. Glassman says, which triggers an "increase in the production of the major skin proteins of the dermis." Which proteins are those? "Collagen and elastin," he says, which both decrease as we age but are needed to "support thinning and aging skin." This technology was once only available in the offices of dermatologists, plastic surgeons and medspas. Now, you can give yourself a red light therapy treatment from the comfort of your own home.

As we age, we want to keep as many cells alive and healthy as possible to combat fine lines, wrinkles, and sagging. Red light therapy achieves this by promoting overall cell health and function while producing more collagen. Collagen is the primary protein that gives our skin, bones, and joints structure — the older we get, the less our bodies naturally produce collagen, leading to increased skin laxity. With more collagen, the skin takes on a firmer, smoother, and more youthful appearance. But collagen production isn’t the only advantage of red light therapy. Photobiomodulation allows the cells to work at the top of their potential, leading to the possibility of many other valuable benefits.

This clinical study confirms the interest of photobiomodulation in the treatment of the signs of skin aging. From the very first sessions, whatever the age of the person, the visible effects of reversing the signs of aging are not only observable but also measurable. During a photobiomodulation therapy, it is important to consider the power and the time of use. Indeed, when the sessions are too long, or when the device does not allow for the treatment of a large surface, compliance decreases. The Red light therapy device has the advantage of treating the entire surface of the face in only 12 min. This is a short time during which cellular metabolisms are stimulated and skin repair and regeneration mechanisms are accelerated.

If you’re wondering if you should incorporate red light therapy into your skincare routine, here’s what dermatologists say you should know—including the low-down on its touted benefits, safety, and risks, and whether at-home treatments are truly worth the money. Red light therapy usually takes the form of a face mask, light panel, or wand equipped with LED lights, which you place near your skin to let your cells “absorb” the light. “Red light therapy is theorized to work on the mitochondria of our cells—the engine,” explains LoGerfo. “This gives the cells of the body more energy, allowing other cells to function with maximum productivity. For the skin, this includes skin restoration and repair which can help increase new cell growth and intensify the restoration process.”

Although there are some studies regarding their benefit, they are not abundant, and we are not entirely sure how they work. One thing that’s important to note about the effectiveness of red light therapy, says Dr. Paulvin, is that it may take consistency and time to notice results. Even then, LoGerfo says that you should have realistic expectations. “People should know that results you usually see with these treatments are mild,” she says. “They aren’t a game changer when it comes to fine lines, wrinkles, hair loss, etc.” Still, red light therapy definitely shows promise in the field of dermatology, especially due to its safe, noninvasive nature and its minimal side effects.

Red light therapy delivers low level wavelengths of red light to the skin. The light is thought to smooth wrinkles by acting on mitochondria, which you might remember from your high school biology class as the “powerhouse” of the cell. Mitochondria generate the energy that skin cells need to repair and regenerate themselves. The light also stimulates fibroblasts, cells that produce the proteins collagen and elastin. “Collagen and elastin are essential for keeping skin firm and smooth. As we age, collagen production naturally slows down, which is why wrinkles and sagging occur,” Kopelman says. “I tell my patients that red light therapy boosts the skin’s ability to rebuild collagen and elastin, leading to a smoother texture, more elasticity, and reduced fine lines. It also helps improve circulation, which brings oxygen and nutrients to the skin.”

In one study, 90 patients received 8 LED red-light treatments to their face over 4 weeks. More than 90% of patients said they noticed some improvement, including softer and smoother skin, less redness, and lightening of dark spots. Similar results have been seen in larger studies. In one large study, dermatologists saw that the patients who received in-office red light therapy after being treated with a laser had less discoloration and swelling from the laser. The results from these and similar studies led the U.S. Food and Drug Administration (FDA) to clear several red-light devices for treating signs of skin aging at home.

FAQ

1. How does red light therapy help with an aging face?

Red light therapy works by penetrating the skin to stimulate mitochondria, boosting energy production in cells. This enhances collagen and elastin production, which are key to maintaining firm, smooth skin. Over time, it can reduce wrinkles, fine lines, and sagging while improving overall skin texture and tone.

2. How long does it take to see results?

Results vary depending on the individual and the device used. Some people notice improvements like smoother skin or reduced redness after a few sessions, while significant changes, such as wrinkle reduction, may take 4-12 weeks of consistent use, typically 2-5 times per week.

3. Is red light therapy safe for all skin types?

Yes, red light therapy is generally safe for all skin types and colors. Unlike UV light, it doesn’t cause burns or increase cancer risk. However, those with photosensitive conditions or taking photosensitizing medications should consult a doctor before starting.

4. Can I use red light therapy at home?

Absolutely! There are many FDA-cleared at-home devices like masks, wands, and panels designed for facial use. While in-office treatments may offer stronger results due to higher intensity, at-home options are convenient and effective with regular use.

5. Are there any side effects?

Side effects are rare and usually mild, such as temporary redness or warmth. Overuse or improper use (e.g., too close to the eyes without protection) might cause discomfort. Always follow device instructions and wear protective goggles if recommended.

6. Does red light therapy replace other anti-aging treatments?

Not entirely. While it boosts collagen and improves skin health, it’s often most effective as part of a broader routine. Dermatologists may pair it with treatments like Botox, fillers, or chemical peels for more dramatic results, depending on your goals.

7. How often should I use red light therapy for my face?

For best results, use it 2-5 times per week, with sessions lasting 10-20 minutes, depending on the device. Consistency is key, as benefits build over time. Check your device’s guidelines for specific recommendations.

8. Can it help with age spots or uneven skin tone?

Yes, studies suggest red light therapy can lighten dark spots and improve complexion uniformity by enhancing circulation and cellular repair. It’s not a quick fix but can gradually even out skin tone with regular use.
