Can Light Therapy Erase Wrinkles by 30%? A New Study Says Yes!
Discover how photobiomodulation slashes periocular wrinkles with a simple, non-invasive approach.
Ever wondered if a simple light could roll back the years on your face? A groundbreaking study reveals that photobiomodulation (PBM), using red and amber LED light, can reduce periocular wrinkle volume by about 30% in just weeks. This isn’t sci-fi—it’s a practical, science-backed approach to rejuvenation that could change how we tackle aging skin.
What’s the Big Idea?
This study, conducted by researchers at Universidade Nove de Julho in Brazil, asked a compelling question: Can specific wavelengths of light—red (660 nm) and amber (590 nm)—rejuvenate skin by reducing wrinkles at the same light dose? The core finding is a resounding yes, with both wavelengths cutting periocular (crow’s feet) wrinkle volume by roughly 30% after 10 sessions over 4 weeks. Using high-resolution imaging, they showed red light slightly outperformed amber, but both delivered impressive results without invasive procedures.
Why Should You Care?
The implications are huge for anyone looking to enhance their appearance or slow skin aging without needles or chemicals. PBM offers a non-inflammatory alternative, ideal for those with conditions like diabetes or keloids where harsher treatments (like peels or ablative lasers) aren’t an option. It’s also a boost for mental well-being—participants reported better quality of life post-treatment, likely tied to visible improvements. This could influence daily skincare routines or even clinical therapies focused on long-term skin health and confidence.
What’s Next on the Horizon?
The research opens doors to exciting possibilities. Future studies could explore longer follow-ups to see if collagen production (stimulated by PBM) yields even greater wrinkle reduction over time. There’s also potential to test amber light for other cosmetic issues like melasma, or to refine protocols for different skin types and ages. Could at-home LED devices become as common as moisturizers? Practical next steps include developing accessible, safe tools for personal use, though more clinical data is needed.
Safety, Ethics, and Caveats
While PBM appears safe—no pain or adverse effects were reported in the study—there are limitations to note. The trial focused solely on women aged 40-65 with specific skin phototypes (II-IV), so results may not apply to men, older individuals, or darker skin tones due to differences in light absorption and aging patterns. Ethically, broader testing is crucial to avoid overhyping benefits for unstudied groups. Also, the study didn’t improve skin hydration or elasticity, and longer-term effects remain unclear. Proceed with informed caution until more diverse data emerges.
What This Could Mean for You
Ready to shine a light on aging? While professional PBM sessions (like those in the study) aren’t yet widely available everywhere, here’s how to act on this research now:
Explore LED Devices: Look for FDA-cleared or clinically tested at-home LED masks or handheld tools with red (around 660 nm) or amber (around 590 nm) wavelengths. Stick to low-intensity options to mimic the study’s safe dose (about 3.8 J/cm²). Use for 10-20 minutes, 2-3 times a week, focusing on areas like crow’s feet.
Combine with Basics: PBM isn’t a magic bullet—pair it with sunscreen (as 69% of participants used daily) to protect gains and a hydration routine, since the study saw no improvement in skin moisture.
Know Your Skin: Effects may vary by age, gender, or lifestyle (e.g., sun exposure habits, noted in 47% of participants). If you’re outside the 40-65 age range or have a different skin phototype, consult a dermatologist to tailor expectations.
Start small, track changes, and remember this is best as a complementary strategy for non-invasive rejuvenation.

Think of PBM like a gentle nudge to your skin cells, coaxing them to rebuild collagen and smooth out wrinkles—without the burn of harsher treatments. As one of the researchers noted, “PBM with red or amber LEDs was similarly effective for wrinkle volume reduction”—a powerful hint at its potential. While it’s not a full fountain of youth yet, especially for hydration or elasticity, it’s a promising step for anyone craving a low-risk glow-up. Stick with science, and let’s see where this light leads!
