How Light Powers Your Cells

Learn how red and near-infrared light stimulate your cells, promote collagen growth, and reduce inflammation, leading to healthier skin.
01 Red and near-infrared light are absorbed by cytochrome c oxidase (CCO), a vital protein in your mitochondria that drives cellular energy production.
02 This absorption triggers increased ATP production, activating the electron transport chain to transform oxygen and nutrients into cellular energy.
03 The rise in ATP enhances cellular signals that stimulate collagen production, reduce inflammation, and support overall skin health.

Blue Wavelength 415–480nm

Reference

Blue light primarily works at the skin’s surface and is widely used in dermatology for acne-prone, oilier skin types. Studies show that it can:

  • Target and destroy acne-causing bacteria
  • Help normalize excess oil production
  • Soothe active breakouts and visible redness

When blue light activates natural porphyrins inside C. acnes bacteria, it creates reactive oxygen species that clear these bacteria without harsh topical agents. At the same time it helps quiet inflammation and rebalance sebum, helping to keep pores from clogging again. Combined with red light, it can further support faster, calmer recovery.

Yellow Wavelength 585–605nm

Reference

Yellow light sits between green and red on the spectrum and is valued for its gentle action on sensitive, redness-prone skin. Current evidence shows that it can:

  • Calm visible redness and irritation
  • Help slow melanin production and angiogenesis
  • Soften the look of sun spots and post-blemish marks

By influencing melanocyte activity and blood vessel formation, 585–590 nm LEDs can help rebalance uneven tone while remaining comfortable on reactive skin. Used alongside other wavelengths, yellow light contributes to a brighter, more uniform complexion over time.

Red Wavelength 630–660nm

Reference

Red light is the most widely studied beauty-focused wavelength range and is closely tied to collagen support and skin rejuvenation. Documented benefits include:

  • Stimulating collagen and elastin synthesis
  • Improving the appearance of fine lines and texture
  • Helping calm redness and inflammatory markers in the skin

By being absorbed in mitochondrial chromophores, red light boosts ATP production and cell metabolism. This supports faster repair of dermal structures, better hydration and a smoother, more radiant surface. Regular exposure at appropriate doses can visibly improve firmness with no downtime or ablation.

Near-Infrared Wavelength 830–880nm

Reference

Near-infrared (NIR) light between 830–880 nm penetrates deeper than visible red, reaching the dermis, subcutaneous tissue and even parts of muscle.

At these depths, NIR can enhance mitochondrial performance, support collagen renewal and help accelerate recovery in injured or stressed tissues. Studies report improved wound closure, reduced inflammatory markers and potential benefits for bone and joint health. Paired with surface-focused red light, NIR provides a more complete rejuvenation and recovery profile from the outside in.

Deep Infrared Wavelength 1064nm

Reference

1064 nm deep infrared penetrates even further into the dermis and subcutaneous fat layers, which is why it is frequently used in non-ablative medical laser systems.

This wavelength can stimulate robust collagen remodeling, soften deep wrinkles and scars and support long-term tone and firmness while keeping the surface of the skin intact. Its anti-inflammatory properties are also useful for redness-prone conditions such as rosacea, with a low risk of post-inflammatory pigmentation when treatment parameters are carefully controlled.

How Red & Near-Infrared Light Can Support Your Body—from Head to Toe.

Wrinkles

Most topical skincare only treats the surface of the skin. Red light therapy works deeper, reaching the cells that power collagen, elastin, and overall skin vitality. By gently energizing these cells, light therapy helps soften the appearance of fine lines and wrinkles that form with age or repeated expression.

Through photobiomodulation, targeted wavelengths stimulate collagen production, support firmer, more elastic skin, and encourage healthy cell turnover. This helps smooth crepey or sagging areas and promotes a more refined texture over time.

Light therapy also supports micro-circulation and nutrient delivery, giving the skin a more radiant, “lit from within” look. Even though we’re exposed to daily environmental stressors, the skin can still respond positively to consistent red and near-infrared light.

Acne

Breakouts often stem from excess oil, clogged pores, and acne-causing bacteria. While prescription treatments can help, they may also cause dryness, irritation, or antibiotic resistance. Light therapy offers a gentle, non-invasive option that targets acne without harsh side effects.

Blue light helps reduce acne-causing bacteria on the skin’s surface, while red light works deeper, calming redness and supporting repair of irritated tissue. Together, these wavelengths help minimize active breakouts and support a clearer, more even complexion.

Because light therapy does not rely on chemicals or medications, it can be a supportive choice for many skin types, including sensitive or easily reactive skin, when used as part of a consistent routine.

Wound Healing

Normal wound repair requires controlled inflammation, new cell growth, and tissue remodeling. Red and near-infrared light support this process by increasing cellular energy, encouraging new blood vessel formation, and promoting better circulation so oxygen and nutrients can reach the affected area.

Light therapy has also been shown to support collagen production, which is vital for strong, resilient tissue and healthy scar formation. By helping tissues repair more efficiently, light therapy can be a valuable adjunct for wound management protocols.

Inflammation

Inflammation is the body’s built-in defense against injury or infection, but when it becomes excessive or chronic it can contribute to pain, tissue damage, and premature aging. Red light therapy helps modulate, rather than completely shut down, this response.

At the cellular level, light therapy can reduce pro-inflammatory mediators, support the clearance of oxidative byproducts, and make cells less reactive to inflammatory triggers. This combination encourages a more balanced healing environment.

Because inflammation is closely linked to immune activity, red and near-infrared light may also help normalize immune responses in targeted areas. This makes light therapy a promising complementary approach for both short-term flare-ups and long-standing inflammatory issues.

Pigmentation

Dark spots and uneven tone—such as melasma, post-acne marks, and sun spots—often arise from excess melanin, oxidative stress, and sluggish cell turnover. When pigment-producing cells are overactive, the skin struggles to maintain an even complexion.

Blue light can help temper melanocyte activity and influence tyrosinase, a key enzyme in melanin formation. Red and near-infrared light support healthy mitochondrial function, improve circulation, and assist with cellular clean-up processes that remove excess pigment over time.

By pairing light therapy with daily sun protection and a gentle skincare routine, many people experience a smoother, more balanced look to their skin tone.

Pain Relief

Pain can be driven by many different issues—from overuse and injury to chronic conditions. Traditional options like medication or injections may help, but often come with side effects or limited long-term use. Light therapy offers a non-drug, non-invasive way to support the body’s natural pain-relief pathways.

Research suggests that specific light wavelengths can influence neurotransmitter release, ease pain-signaling activity, and promote circulation in targeted areas. This can help deliver oxygen and nutrients more efficiently, remove waste products, and reduce inflammation-related discomfort.

Because it can be used repeatedly without systemic side effects, light therapy is a promising complementary option for both occasional flare-ups and ongoing joint or muscle soreness.

Body Contour

Sustainable body shaping is built on smart nutrition and movement, but targeted light may help support those efforts. Red light therapy has been studied for its potential to influence fat cell biology and metabolic activity in areas where it’s applied.

By affecting the membranes of fat cells, certain wavelengths can help release stored contents, which the body can then process and eliminate through normal metabolic pathways. Combined with regular exercise and a balanced lifestyle, this may contribute to a more refined silhouette over time.

Because light therapy is non-invasive and does not rely on heat or cutting, it’s often used as a gentle complement to traditional weight-management routines rather than a replacement for them.

Hair Growth

Thinning hair and hair loss affect millions of people worldwide. As a non-drug approach, low-level light therapy has gained attention for its potential to stimulate follicles and support thicker, healthier-looking hair.

Red and near-infrared wavelengths can energize follicular stem cells, encourage dormant follicles to re-enter the growth phase, and help maintain active follicles for longer. At the same time, improved circulation brings more oxygen and nutrients to the scalp, creating a supportive environment for hair growth.

Used consistently over time, light therapy can be a useful complement to other hair-care routines for those looking for drug-free options.

Sleep and Depression

Sleep and mood are tightly connected. Ongoing sleep disruption can raise the risk of low mood, while poor mood can make it harder to fall and stay asleep. Light exposure is one of the main signals that helps keep these rhythms on track.

Morning light helps suppress nighttime melatonin and promote daytime alertness, while appropriate evening routines support melatonin release and deeper sleep. Certain light protocols have also been studied for their ability to support people with seasonal mood changes and other mood-related concerns.

When used thoughtfully alongside healthy habits and professional care when needed, light-based approaches can be a useful tool for supporting both restorative sleep and emotional well-being.
