Frequently Asked Questions

Red light therapy, also known as photobiomodulation, uses specific wavelengths of red and near-infrared light (typically 660-850nm) to stimulate cellular processes. The light penetrates the skin and is absorbed by mitochondria, leading to increased ATP production, improved cellular function, and various therapeutic benefits.

Red light therapy has been shown to help with skin health (anti-aging, acne, wound healing), pain relief, muscle recovery, improved circulation, better sleep quality, and reduced inflammation. Benefits can vary by individual and specific condition being treated.

For most conditions, 3-5 sessions per week is recommended. Daily use is generally safe for most people. Start with 3 sessions per week and adjust based on your response and goals. Consistency is more important than frequency.

Session length depends on the device power and distance. Typically, 10-20 minutes per session is recommended. Start with shorter sessions (5-10 minutes) and gradually increase. Higher-powered devices may require shorter sessions.

Yes, red light therapy works best on bare skin. Clothing, lotions, and makeup can block or reduce light penetration. Clean, dry skin provides optimal light absorption for maximum benefits.

Red light (660nm) primarily affects surface tissues and is excellent for skin health, while near-infrared light (850nm) penetrates deeper into muscles, joints, and organs. Many devices combine both wavelengths for comprehensive benefits.

Key factors include: wavelengths (660nm and/or 850nm), power density/irradiance, treatment area size, build quality, FDA registration, warranty, and third-party testing. Avoid devices that don't specify wavelengths or power output.

LED panels cover larger treatment areas and are ideal for full-body or large area treatment, while handheld devices are portable and better for targeted spot treatment. Panels typically offer higher power density and are more efficient for regular use.

Not necessarily. While quality components and higher power output often cost more, the most expensive device isn't always the best for your needs. Consider your specific goals, treatment area size, and budget. Many mid-range devices offer excellent value.

Red light therapy is generally considered very safe when used properly. It's non-invasive, doesn't cause burns like UV light, and has minimal side effects. However, you should protect your eyes, start with shorter sessions, and consult a healthcare provider if you have specific medical conditions.

Side effects are rare but may include temporary eye strain if proper eye protection isn't used, mild headaches in sensitive individuals, or temporary skin irritation. Contraindications include pregnancy (without medical supervision), certain medications that increase light sensitivity, and active cancer in the treatment area.

While red light therapy is generally safe, pregnant women should consult with their healthcare provider before use. There isn't extensive research on red light therapy during pregnancy, so medical supervision is recommended.

Yes, eye protection is important. Never look directly at LED lights. Many people close their eyes or use protective eyewear. Some devices come with eye protection, or you can purchase safety glasses designed for red light therapy.

Most devices work best at 6-12 inches from the skin. Closer distances provide higher intensity but cover smaller areas. Follow your device manufacturer's recommendations, as optimal distance varies by device power and design.

Yes, you can use multiple devices to cover larger areas or combine different wavelengths. Just be mindful of total treatment time and don't exceed recommended exposure limits. Some people use panels for body treatment and handheld devices for facial care.

Results vary depending on the condition being treated and individual factors. Some people notice improvements in energy and mood within days, while skin benefits typically become visible after 2-4 weeks of consistent use. For deeper tissue healing and pain relief, it may take 6-12 weeks to see significant improvements.
