Collagen Production, Skin and Wrinkles

Blue light has been shown to help with acne, however it should be used in moderation because it also prematurely ages skin. For this reason our Hero Series red light therapy masks have a blue light option which is not on by default, so you can use it only when you want to.

• 415 nm Blue and 830 nm NIR LED Combination for Moderate Acne
  
  A trial on patients with moderate acne vulgaris using combined 415 nm blue and 830 nm near-infrared LED therapy showed notable reductions in acne lesions, inflammation, and scarring, improving skin health safely as a non-invasive option.

• 415 nm Blue LED and Mixed Blue/Red Light for Acne Treatment
  
  In a study with 107 patients with mild to moderate acne, treatments twice a week for 15 minutes using 415 nm blue LED light alone reduced inflammatory lesions by 25% after 5 weeks, while combined blue and 660 nm red light cut them by 76% over 12 weeks, making skin clearer with fewer pimples and no side effects.

• Self-Applied 415 nm Blue LED Therapy for Mild-to-Moderate Acne
  
  Thirty adults with mild-to-moderate acne used a handheld blue LED device at 415 nm twice daily for 4 weeks, resulting in a significant 50% drop in acne spots by week 8, with continued improvement up to 12 weeks, offering an easy, at-home way to clear skin without irritation.

• 415 nm Blue LED with Red Light for Inflammatory Acne
  
  Reviewing multiple studies, combining 415 nm blue LED light (which kills acne-causing bacteria) with red light effectively reduced inflammatory acne pimples by targeting bacteria and soothing skin, leading to clearer complexions with minimal treatments.
  

HeroMask Elite and Core have an optional 415nm blue light setting

• 630 nm LED mask reduces crow's-feet depth by 38% and raises dermal density by 48% (630 nm)
  
  Twenty adults aged 45-70 (15 women, 5 men) used a 630 nm red LED mask for 12 minutes twice a week for three months. Crow's-feet wrinkle depth fell by 38.3%, ultrasound dermal density rose 47.7%, and roughness, pore size and sebum all decreased; effects persisted a month after stopping. It was a small, uncontrolled study with a branded device.

• Home 630 nm + 850 nm LED mask improves crow's feet in a sham-controlled trial (630 nm)
  
  In a multi-centre, randomised, double-blind trial, 59 adults aged 30-65 used a mask emitting 630 nm red and 850 nm near-infrared light for 9 minutes, five days a week, for 12 weeks. Blinded raters judged crow's feet improved in 86.2% of the active group versus 16.7% of the sham group, with only minor side effects. Collagen was not measured directly.

• Home 630 nm + 850 nm LED neck device improves neck wrinkles in 77% of users (630 nm)
  
  Seventy adults were randomised to a neck device emitting 630 nm and 850 nm light or a sham device for 9 minutes a day, five days a week, for 12 weeks. Investigators graded neck wrinkles as improved in 77.1% of the treatment group versus 8.6% of controls, with no thyroid changes on ultrasound. Assessment was visual only; elasticity and collagen were not measured.

• 630 nm LED Protects Skin Collagen from UV Damage
  
  In hairless mice exposed to UV radiation, pretreatment with 630 nm red LED light preserved collagen fiber density and arrangement, reduced skin thickening and inflammation, and enhanced overall skin barrier health, suggesting benefits for anti-aging and wrinkle prevention.

Note: There is a practical overlap between 630nm and 633nm red light, however we have chosen 633nm for the HeroMask Elite because it is used more in LED face mask skin health research.

• 660 nm LED Boosts Collagen and Reduces Wrinkles
  
  In lab tests and a trial on people with aged skin, pulsed 660 nm LED light treatments increased collagen levels by 31% and lowered wrinkle-causing enzymes by 18%, resulting in smoother skin and reduced wrinkles for over 90% of participants.

• 660 nm red LED cuts periocular wrinkle volume by 31.6% in 137 women
  
  In a randomised split-face trial, 137 women aged 40-65 had ten sessions over four weeks of 660 nm red light on one side of the face and 590 nm amber on the other (3.8 J/cm²). Red light reduced periocular wrinkle volume by 31.6% (amber 29.9%), without changing hydration or elasticity, and quality of life improved.

• 660 nm LED Modulates Collagen in Tissue-Engineered Skin
  
  Using a 3D human skin model, 660 nm LED light at 4 J/cm² upregulated collagen and downregulated MMP-1, leading to better skin texture; a related clinical trial showed over 90% reduction in wrinkle depth and roughness.

• 830 nm LED, alone or with 633 nm, reduces wrinkles by up to 36% in a 76-patient double-blind trial (830 nm)
  
  Seventy-six patients were randomised to 830 nm alone, 633 nm alone, both, or sham light on half the face, twice a week for four weeks. Wrinkles decreased by up to 36% and elasticity increased by up to 19%; skin biopsies showed more collagen and elastic fibres and activated fibroblasts, with no adverse effects.

• Combined 633 nm and 830 nm LED Improves Skin Texture and Wrinkles
  
  Thirty-one participants received nine treatments of 633 nm red and 830 nm near-infrared LED light over five weeks, resulting in 52% achieving 25-50% better photoaging scores, 81% noticing significant reduction in periorbital wrinkles, and overall smoother, softer skin.

• 633 nm, 830 nm, and 1072 nm LED Mask Rejuvenates Male Skin
  
  In a 6-week home-use study on men, an LED face mask with 633 nm red, 830 nm near-infrared, and 1072 nm light improved fine lines, wrinkles, skin texture, pores, and spots, with participants reporting a more youthful appearance and healthier skin.

• 633 nm, 830 nm and 1072 nm LED mask rejuvenates male facial skin in six weeks (1072 nm)
  
  Men used a home LED face mask emitting 633 nm, 830 nm and 1072 nm light for six weeks. Participants reported the greatest improvements in fine lines, wrinkles and skin texture, and digital photo analysis showed improvements in wrinkles, UV spots, brown spots, pores and porphyrins, with the treatment judged safe and convenient. Collagen was not measured.

• 1072 nm Light Reduces Wrinkles and Fine Lines in Self-Reported Trial
  
  In a randomized, double-blind, placebo-controlled trial, participants applied 1072 nm light daily around the eyes for 6-8 weeks, with 52-57% accurately identifying improvements in fine lines and wrinkles, and 37-46% noting reduced bags under the eyes, demonstrating efficacy for anti-aging skin health.
