As we age, our skin’s natural collagen breaks down, leading to fine lines, wrinkles, and loss of elasticity. In the quest for youthful skin, many are turning to red light therapy – a non-invasive treatment that uses low-level red and near-infrared light to rejuvenate the skin.
But does shining a red light on your face help reduce wrinkles and signs of aging? Emerging research and clinical evidence suggest that it can. Red light therapy (RLT), also known as photobiomodulation, penetrates the skin and stimulates cells to produce collagen and elastin, the proteins that keep skin firm and smooth.
The result is improved skin texture and a reduction in the appearance of wrinkles over time. Below, we explore how red light therapy works for anti-aging, what the studies show, and how to use it effectively for younger-looking skin.
Key Takeaways:
- Red light therapy boosts collagen production in the skin, which helps reduce fine lines and wrinkles for a more youthful appearance.
- Clinical studies have found significant improvements in skin complexion, hydration, and wrinkle depth after a series of red light treatments.
- RLT is gentle and non-invasive, causing no damage to the skin. It’s generally considered safe with minimal side effects when used properly.
- Consistent use is key: most users see gradual results over several weeks, and maintenance sessions help sustain collagen levels.
- At-home red light devices (like NovaaLab’s light therapy panels) make it convenient to do anti-aging treatments regularly as part of a skincare routine.
How Does Red Light Therapy Fight Wrinkles?
Red light in certain wavelengths (typically around 600–700 nm) penetrates into the dermis, the skin layer where collagen and elastin fibers reside. This light energy is absorbed by cells, notably by the mitochondria (the cell’s energy centers), and can stimulate a cascade of cellular processes. One outcome is increased ATP production – essentially giving cells more energy to carry out repair and regeneration. In skin, this means fibroblast cells can ramp up the production of collagen and elastin, helping to plump and firm the skin from within. Over time, higher collagen levels improve skin elasticity and reduce wrinkle depth.
Red light therapy also promotes better circulation by dilating blood vessels (vasodilation) in treated areas. This improved blood flow brings more oxygen and nutrients to skin tissues, supporting a healthier complexion and glow. Additionally, RLT has an anti-inflammatory effect – it calms redness and may help skin repair processes. These combined effects (boosting collagen, increasing circulation, reducing inflammation) tackle multiple causes of skin aging at once.
Evidence of Anti-Aging Benefits
Multiple studies and clinical trials have evaluated red light therapy for anti-aging, and results are promising. In one controlled trial, participants received red light treatments to the face twice weekly for several weeks. By the end of 30 sessions, significant improvements in skin complexion, skin smoothness, and collagen density were measured in treated subjects compared to a control group.
Blinded dermatologists assessing photos noted visible reductions in wrinkles and finer lines in those who had RLT. These findings align with other research showing that red light can “plump up” skin features in humans by increasing collagen production. In plain terms, skin treated with red light tends to become firmer and more elastic, which naturally softens the look of wrinkles.
Even outside of formal studies, dermatology experts acknowledge the benefits. The Cleveland Clinic states that red light therapy can improve the skin’s appearance by reducing wrinkles, scars, and redness. And in the realm of cosmetic devices, low-level light therapy has been FDA-cleared for improving skin texture and reducing facial wrinkles, which lends further credibility to its efficacy.
It’s important to note that while results are positive, they are gradual. Red light therapy is not an instant fix or as dramatic as invasive procedures. Instead, it gently supports the skin’s own renewal. Many trials report noticeable changes after about 8–12 weeks of regular treatments. Patience and consistency are rewarded with smoother, healthier-looking skin.
Using Red Light Therapy for Younger-Looking Skin
One of the appeals of red light therapy is that it’s easy to use, painless, and requires no downtime. Treatments can be done in dermatology clinics, med spas, or right at home with LED devices. Here are some tips for effective use:
• Choose a Quality Device: If treating at home, use a reputable red light therapy device that delivers wavelengths in the red (around 630–670 nm) and possibly near-infrared (around 800–880 nm) range. NovaaLab offers high-quality LED panels and lamps designed for skin treatments, emitting therapeutic light intensities for optimal collagen stimulation. A good device will cover your face evenly and be powerful enough to deliver the needed energy within a reasonable session time (typically 10–20 minutes).
• Cleanse and Prep Skin: Start with clean, makeup-free skin so that the light can penetrate without barriers. Unlike laser treatments, no gel is required – simply remove any sunscreen or cosmetics beforehand.
• Optimal Treatment Schedule: Follow the guidelines of your device, but a common routine is 3–5 sessions per week for the first 1–2 months. Each session usually lasts about 10 minutes per area. For a full face treatment, you might do 10 minutes per side or position if using a smaller panel, or 10–20 minutes total if using a larger panel that covers the whole face at once. Consistency is key – regular exposure triggers cumulative improvements.
• Distance and Safety: Position the light at the recommended distance (often a few inches away). You should feel gentle warmth at most. Keep your eyes closed during facial treatments, and consider wearing the provided goggles if the device is very bright, to prevent any eye discomfort. Red light therapy is generally very safe and not associated with harmful UV rays or skin damage, but eye protection is advised for comfort when treating near the eyes.
• Patience with Results: It typically takes several weeks to start seeing subtle improvements, such as a “glow” or better skin plumpness. After 8–12 weeks, many users notice a reduction in fine lines, improved tone, and firmness. Photographing your face before and after a treatment series can help document these changes, since they accumulate gradually.
Bringing Clinic-Grade Light Home With Novaalab
Professional dermatology offices have used light therapy for years to refresh aging skin. Now, at-home devices make it accessible to continue treatments regularly. NovaaLab’s red light therapy products are designed with anti-aging in mind – delivering the same red and near-infrared wavelengths used in studies, at safe power densities for home use.
By using NovaaLab in your skincare regimen, you can conveniently give your skin frequent collagen-boosting exposure. Think of it as “exercise” for your skin cells: just as muscles get stronger with consistent workouts, your skin can become smoother and firmer with consistent RLT sessions.
Of course, red light therapy can complement, not replace, other good skincare practices. Wearing sunscreen daily, using moisturizers or serums with proven ingredients (like retinol or vitamin C), and leading a healthy lifestyle (hydration, balanced diet, not smoking) will all enhance and maintain the anti-aging effects. Red light simply gives your skin an extra advantage by energizing its natural renewal processes.

FAQ: Red Light Therapy for Wrinkles
Q: How long does it take to see results in wrinkle reduction?
A: Most people need to use red light therapy consistently for several weeks before seeing noticeable changes. Minor improvements in skin radiance and hydration can appear after the first month of regular use.
Significant reductions in fine lines or deeper wrinkles typically emerge around the 8–12 week mark, as collagen builds up. Keep in mind that results vary based on age, skin condition, and how often you use the therapy. Patience is important – changes are gradual but can be meaningful with continued use.
Q: Can red light therapy completely remove wrinkles?
A: Red light therapy is best at softening and reducing the appearance of wrinkles, not outright erasing them. It won’t deliver the same effect as an invasive procedure like a facelift or laser resurfacing. However, many users find that their fine lines diminish and deeper creases become less pronounced.
Skin texture and tone improve as well, which makes wrinkles less noticeable. The therapy essentially helps your skin help itself – by boosting collagen and elastin, it can achieve a more youthful look, but within natural limits. Think of it as turning back the clock a bit, not stopping time entirely.
Q: Is it safe to use red light therapy on delicate areas like around the eyes?
A: Yes, treatments can be done on the crow’s feet area and under-eye region – those fine lines often respond well to RLT. The red light wavelengths used for skin rejuvenation are gentle and do not damage the eyes or skin. That said, the brightness of LEDs can be uncomfortable if shone directly in the eyes.
It’s recommended to keep your eyes closed or wear protective goggles when treating around the eye area. Also, avoid pressing a device too close to the eyeball. Used correctly, RLT is a safe method to improve the appearance of fine lines around the eyes, and many people use it specifically to target those concern areas.
Q: Will the improvements last if I stop using the red light therapy?
A: The gains in collagen and skin quality can last for some time, but they may gradually diminish if therapy is discontinued. Natural aging will continue, so maintenance sessions are beneficial. Some experts note that when people stop regular red light treatments, the skin might slowly revert to its prior state over a number of months.
To sustain the youthful collagen levels you’ve achieved, it’s a good idea to do periodic “touch-up” sessions – for example, 1–2 times per week after the initial intensive period. This helps maintain the skin benefits for the long term.
Q: Can I combine red light therapy with other skincare treatments?
A: Absolutely. Red light therapy works well alongside other skincare routines. You can use your normal cleansers, topical anti-aging serums (like retinoids, hyaluronic acid, peptides, etc.), and moisturizers. Applying a hydrating serum after RLT can be especially effective, as the increased blood flow might improve absorption. If you receive professional treatments like chemical peels, microdermabrasion, or microneedling, consult your dermatologist, but generally, RLT can be used a few days after such treatments to promote healing.
Always avoid using RLT on actively inflamed or broken-out skin (to be safe with conditions like active acne or open wounds), unless directed by a healthcare provider. Otherwise, it’s a versatile addition to a multi-faceted skincare and anti-aging plan.
