Frequently Asked Questions

Red light therapy, also known as photobiomodulation (PBM), is a non-invasive treatment that uses specific wavelengths of red and near-infrared light (typically 630-1060nm) to stimulate cellular function. When these wavelengths penetrate your skin, they are absorbed by mitochondria, triggering increased ATP (cellular energy) production, reduced inflammation, and enhanced tissue repair.

Red light therapy works at the cellular level. Photons of red and near-infrared light are absorbed by cytochrome c oxidase, a photoacceptor in your mitochondria. This absorption displaces nitric oxide, allowing oxygen to bind more efficiently and accelerating the electron transport chain. The result is up to 150% increase in ATP production, which powers cellular repair, regeneration, and optimal function throughout your body.

Yes, red light therapy is considered very safe when used as directed. Unlike UV light, red and near-infrared wavelengths do not damage skin or cause burns. Verso Light devices are FDA 510(k) cleared as Class II medical devices, meaning they have undergone rigorous safety testing. The most common side effect is temporary eye strain if used without eye protection, which is why we recommend closing your eyes or using protective goggles during facial treatments.

Red light therapy is safe for most adults. However, certain individuals should consult their healthcare provider first: those who are pregnant, have active cancer, are taking photosensitizing medications, have epilepsy, or have thyroid conditions (when treating the neck area). Children should only use red light therapy under medical supervision.

For optimal results, we recommend using red light therapy 3-5 times per week. Many users see benefits with daily use, especially during the first 4-8 weeks. Consistency is more important than duration - regular shorter sessions are more effective than occasional longer ones. After achieving your initial goals, maintenance sessions of 2-3 times per week are typically sufficient.

Session length depends on your device's irradiance (power output) and your treatment goals. With Verso Light panels delivering 180+ mW/cm² at 6 inches, typical sessions range from 10-20 minutes per treatment area. For general wellness, 10-15 minutes is sufficient. For targeted concerns like muscle recovery or skin rejuvenation, 15-20 minutes may be more beneficial. Always follow your device's specific guidelines.

The optimal distance is typically 6-12 inches from the device. At 6 inches, you receive maximum irradiance (power) for concentrated treatment. At 12-18 inches, the light spreads over a larger area at lower intensity, which is useful for full-body sessions. Verso Light panels are calibrated and tested at 6 inches, delivering 180+ mW/cm² at this distance.

Red light therapy can be used any time of day, as it does not contain the blue wavelengths that disrupt circadian rhythm. Many users prefer morning sessions to energize their day, while others use it in the evening for recovery and relaxation. The best time is whenever you can maintain consistency. Note: We exclude blue light from our panels specifically to ensure circadian safety.

Yes, daily use is safe and often beneficial, especially when starting out. Your cells can effectively utilize the energy from red light therapy each day. Some users prefer an "on-off" schedule (5 days on, 2 days off) to allow for cellular adaptation, but there is no harm in daily use. Listen to your body and adjust based on your response.

The most researched and effective wavelengths are 630nm and 660nm (visible red) for surface-level benefits, and 810nm, 830nm, and 850nm (near-infrared) for deeper tissue penetration. Verso Light panels include all six therapeutic wavelengths (630nm, 660nm, 810nm, 830nm, 850nm, and 1060nm) to provide comprehensive coverage from skin surface to deep tissue.

Red light (630-700nm) is visible and penetrates 1-3mm into the skin, making it ideal for skin health, collagen production, and surface-level healing. Near-infrared light (700-1100nm) is invisible and penetrates 4-6cm into tissue, reaching muscles, joints, and organs. For comprehensive benefits, devices should include both ranges. Our panels combine both for full therapeutic coverage.

Irradiance measures the power density of light, expressed in milliwatts per square centimeter (mW/cm²). Higher irradiance means more light energy reaches your cells in less time. Clinical studies typically use 30-100 mW/cm², while Verso Light panels deliver 180+ mW/cm² at 6 inches - placing them in the optimal therapeutic range for efficient, effective treatments.

EMF (electromagnetic field) is produced by electrical devices. Some red light panels using AC drivers produce elevated EMF levels. Verso Light panels use DC drivers that produce 0.0 µT (microTesla) at treatment distance, eliminating EMF exposure entirely. This is verified through independent third-party testing.

Flicker occurs when lights rapidly turn on and off, often imperceptible but potentially causing eye strain, headaches, and fatigue. Many LED panels use PWM (pulse width modulation) dimming that creates flicker. Verso Light panels use constant-current DC drivers that provide true 0% flicker output for comfortable, strain-free treatments.

Red light therapy has been studied for numerous benefits including: skin rejuvenation and collagen production, muscle recovery and performance, joint pain and inflammation reduction, wound healing, hair growth stimulation, mood and sleep improvement, and cellular energy enhancement. Benefits are backed by over 4,000 peer-reviewed studies. Results vary by individual and condition.

Results timeline varies by goal. Many users notice improved energy and mood within 1-2 weeks. Skin improvements typically appear within 4-8 weeks of consistent use. Muscle recovery benefits are often felt immediately. Joint and pain relief may take 2-4 weeks. For chronic conditions, 8-12 weeks of consistent use is recommended before evaluating results.

Yes, red light therapy is one of the most well-researched treatments for skin rejuvenation. Studies show it stimulates fibroblast activity, increasing collagen and elastin production. The 630nm and 660nm wavelengths are particularly effective for reducing fine lines, improving skin texture, and enhancing overall skin tone. Most users see visible improvements within 4-12 weeks.

Yes, red light therapy is widely used by athletes for muscle recovery. Near-infrared wavelengths (810-850nm) penetrate deep into muscle tissue, reducing inflammation, decreasing delayed onset muscle soreness (DOMS), and accelerating repair. Studies show up to 50% faster recovery times when used before and after exercise.

Red light therapy has demonstrated significant benefits for various types of pain. It reduces inflammation, increases blood flow, and promotes tissue repair. Clinical studies show effectiveness for joint pain, arthritis, back pain, and neuropathy. The near-infrared wavelengths (810-1060nm) are particularly effective for deep tissue pain relief.

Yes, Verso Light devices are FDA 510(k) cleared as Class II medical devices for general wellness and pain management applications. This clearance means our devices have undergone rigorous testing for safety and efficacy. You can verify our clearance through the FDA's 510(k) database.

All Verso Light panels come with a comprehensive 3-year warranty covering manufacturing defects and component failures. This is one of the longest warranties in the industry. Our warranty includes advance replacement - if an issue arises, we ship your replacement before you return the defective unit.

We offer a 60-day risk-free home trial on all Verso Light panels. Use your device for a full 60 days - if you're not completely satisfied with the results, return it for a full refund. There are no restocking fees, and we cover return shipping. We believe in our products and want you to experience the benefits firsthand.

Yes, every Verso Light panel ships with protective goggles. While red and near-infrared light is not harmful to eyes like UV light, direct exposure to high-intensity LEDs can cause temporary discomfort. We recommend using the included goggles or simply closing your eyes during facial treatments.

Verso Light panels require minimal maintenance. Wipe the LED surface gently with a soft, dry microfiber cloth to remove dust. Do not use liquids, chemicals, or abrasive materials on the LEDs. Keep the panel in a dry environment and store it in the included protective cover when not in use. The LEDs are rated for 50,000+ hours of use.
