Healthy, radiant skin is the result of balanced cellular activity and resilient tissue. Red and near-infrared light therapy offer a gentle, science-backed approach to improve skin quality, support repair, and enhance complexion—without needles or downtime.
How does it work?
Red and near-infrared wavelengths interact with skin cells in a process called photobiomodulation (PBM), enhancing cellular energy and guiding balanced repair.
Red light (surface-focused): Primarily absorbed in the epidermis and upper dermis. It stimulates fibroblasts to promote collagen and elastin synthesis, supports barrier repair, refines texture, and calms surface inflammation.
Near-infrared light (deeper action): Reaches deeper dermal layers and subdermal tissue. It helps improve microcirculation, modulate inflammation, and support remodeling of extracellular matrix—useful for firmness, tone, and recovery.
Blue light (clarifying effect): Targets the outermost skin layers and is especially effective against bacteria associated with blemishes. Blue light helps purify the skin’s surface, reduce breakouts, and calm overactive sebaceous glands—supporting a clearer complexion.
Orange light (revitalizing glow): Penetrates slightly deeper than blue light and helps energize the skin. It enhances microcirculation, supports oxygen supply, and gives a revitalizing boost for a brighter, more even tone. Orange light is often valued for restoring radiance and reducing dullness.
At the cellular level, photons are absorbed by cytochrome c oxidase in the mitochondria, improving electron transport and increasing adenosine triphosphate (ATP)—the cell’s energy currency.
With more ATP available, skin cells can:
Accelerate barrier repair and tissue regeneration
Boost collagen production and matrix organization
Reduce pro-inflammatory signaling and redness
Enhance turnover for a clearer, smoother complexion
PBM also promotes local vasodilation (via nitric oxide release), improving nutrient delivery and lymphatic drainage—key for glow and reduced puffiness.
Applications for skin & beauty
Light therapy is a versatile, non-invasive addition to modern skincare routines and in-clinic protocols.
Common areas of application include:
Fine lines & loss of firmness Stimulates fibroblasts to increase collagen and elastin, helping soften lines, improve elasticity, and support a firmer look.
Texture & radiance Encourages balanced cell turnover and microcirculation for smoother texture, refined pores, and a healthy glow.
Redness & sensitivity Modulates inflammatory pathways and supports barrier repair to reduce visible redness and reactivity.
Blemish-prone skin Helps calm inflammation around breakouts and supports cleaner recovery without excessive dryness or irritation.
Post-treatment recovery & wound healing Supports faster, cleaner healing after cosmetic procedures (e.g., peels, microneedling) and can improve the appearance of recent scars.
Neck, décolletage & hands Targets commonly exposed areas to improve tone, smoothness, and visible signs of photoaging.
Across these use cases, light therapy acts as a safe, drug-free, and complementary modality that enhances the skin’s natural renewal processes.
Key benefits at a glance
By energizing skin cells and balancing inflammation, light therapy nurtures healthier, more resilient skin from within.
Core benefits include:
Collagen & elastin support Encourages fibroblast activity for firmer, bouncier skin and softened lines.
Improved barrier & hydration Supports barrier lipids and repair—skin feels calmer, looks smoother, and retains moisture better.
Brighter, more even tone Helps reduce visible redness and post-blemish marks; promotes a more uniform complexion.
Soothing anti-inflammatory effect Calms irritated skin and reduces the look of swelling or puffiness.
Gentle & non-invasive No needles, no downtime, and suitable for regular, long-term use.
Together, these mechanisms make light therapy a powerful adjunct to professional treatments and daily skincare, enhancing results while maintaining skin comfort.
Who can benefit?
Light therapy suits anyone seeking smoother texture, improved firmness, calmer skin, and a natural glow. It’s ideal for skincare minimalists and enthusiasts alike, and pairs well with most routines.
How to use it in practice
A typical session lasts 10–20 minutes, 3–5 times per week for 4–8 weeks, followed by a maintenance rhythm. Many users notice enhanced radiance within the first few sessions, with visible improvements in smoothness and firmness over time.
What doctors & professionals say about redtreat®
Dr. med. Wiebke Gruber - Medical specialist in internal medicine
We tested the SolisPanel 3000 in our clinic over several weeks. Some patients with skin problems such as neurodermatitis and severe fatigue underwent regular sessions of 20 minutes 2–3 times a week during this period. After just ten treatments, they reported a significant improvement in their symptoms, either in the form of soothed skin or increased energy in their everyday lives.
MSc, BEng, Dina Holzapfel - Co-Founder red. house of Collagen
When it comes to purchasing red light therapy devices, it’s essential to understand the specifications and to trust that the manufacturer delivers on their promises. That’s why redtreat is my top recommendation in Switzerland. The founders have a deep scientific understanding of the therapeutic principles behind red light therapy and go above and beyond with their customer service and education. I’m very impressed with their expert guidance and ongoing support to ensure you choose the right product for your needs and achieve the results you’re looking for.
Dr. med. Christian Fahe - Specialist in nephrology and internal medicine FMH
We have been using SolisHead for some time now in our clinic for aesthetic treatments. Patients with skin problems such as blemishes, redness, or swelling after procedures have undergone 2–3 sessions per week, each lasting approximately 15–20 minutes. After just a few applications, there was a visible improvement in skin appearance, faster regeneration after aesthetic treatments, and an overall fresher appearance of the skin.
