Healthy, vibrant-looking skin reflects balanced cellular activity and effective self-regulation. Over time, the skin’s ability to renew itself naturally slows—cellular energy production decreases, and collagen and elastin fibers lose structure. Red and near-infrared light therapy offer a gentle, science-informed approach to support skin vitality as part of cosmetic and wellness routines.
How does light therapy work?
Red and near-infrared light interact with the skin at a cellular level through a mechanism known as photobiomodulation (PBM). Light at specific wavelengths—commonly 630 nm, 660 nm, 810 nm, 830 nm, and 850 nm—can be absorbed by components within the mitochondria, influencing cellular energy metabolism (ATP production) and contributing to a more balanced cell environment.
This process has been investigated in cosmetic and basic research for its potential to:
Encourage fibroblast activity involved in collagen organization
Support local circulation and oxygen exchange
Reduce oxidative stress in skin cells exposed to environmental factors
A controlled study using 630 nm LED light reported improvements in skin smoothness and elasticity after a 12-week program (Couturaudet al., 2023). Another trial combining 630 nm and 850 nm demonstrated positive outcomes in skin texture and tone in a non-invasive rejuvenation setting (Hyun et al., 2025).
Applications for skin vitality
Light therapy is designed to complement aesthetic care, supporting the appearance of smoothness, radiance, and firmness through gentle, non-contact use. The technique can be integrated into professional and at-home routines.
Common areas of application include:
Facial care: Sessions using 630–660 nm and 810–850 nm ranges to support even texture and tone.
Neck & décolleté: Regular use to maintain a refined, cared-for appearance.
Hands: Gentle light exposure for comfort and uniform tone.
Post-routine balance: After non-invasive skincare steps such as cleansing or mask use.
A study investigating 633 nm and 830 nm light found increased fibroblast activity and improved skin tone with regular exposure (Lee, S. et al. (2007, reviewed 2024).
Key benefits at a glance
Cosmetic light therapy aims to enhance skin comfort and appearance through routine, non-invasive sessions.
At-a-glance advantages:
Supports the skin’s natural regenerative rhythm
Encourages smooth, luminous texture
Non-invasive, comfortable, and contact-free
Complements everyday skincare habits
Suitable for different skin types and lifestyles
Research exploring 810 nm and 1060 nm light absorption in skin tissue also provides insight into how these wavelengths interact with deeper layers, potentially supporting balanced cellular processes (Frontiers in Photonics, 2024).
Who can benefit?
Light therapy is suitable for individuals looking to maintain a fresh, radiant, and balanced-looking complexion through non-invasive, light-based care. It can be used as part of wellness routines, beauty protocols, or aesthetic practices focused on skin appearance and self-care.
How to use it in practice
Face: 10–20 minutes of red or near-infrared light exposure, 3–5 times per week.
Neck & décolleté: 10 minutes per area, 2–3 times per week.
Hands: 5–10 minutes, 2–3 times per week.
Consistency matters more than intensity. Sessions can be easily integrated into existing skincare or relaxation routines.
Scientific context
The foundation of redtreat technology is aligned with the growing body of research exploring light–tissue interaction. A comprehensive review on red and near-infrared light in dermatology summarizes evidence on mitochondrial stimulation, oxidative balance, and collagen-related mechanisms in cosmetic contexts (Hernandez-Bule et al., 2023).
These studies provide contextual insight into how specific light wavelengths are investigated in relation to skin health and vitality—without implying therapeutic or clinical outcomes for redtreat devices.

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.

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.
