Wondering how often to use Red Light Therapy? Short answer: 3–5 times a week—just enough to glow without overcooking! Whether you’re using Red Light Therapy Panels or fancy Red Light Therapy Beds, this guide breaks down the perfect routine. Read on to avoid turning into a tomato.

What is Red Light Therapy?
Red light therapy is a non-invasive treatment that uses specific wavelengths of light to stimulate your body's natural healing processes. It’s commonly used to improve skin, ease pain, and boost recovery. You’ll often see it referred to as photobiomodulation.
How RLT Works (Mitochondrial Stimulation, Cellular Repair)
When red or near-infrared light hits your skin, it’s absorbed by the mitochondria in your cells. This boosts energy production and helps the body repair itself faster. The process promotes tissue repair, reduces inflammation, and improves circulation.
Key Wavelengths (Red and Near-Infrared Light)
Red light typically ranges from around six hundred to seven hundred nanometres. Near-infrared light is slightly longer, from around seven hundred to one thousand nanometres. These wavelengths penetrate skin and muscle at different depths, offering distinct therapeutic effects.
The Wide Range of RLT Benefits
Red light therapy is popular for its wide variety of wellness applications. Whether you’re tackling wrinkles or sore knees, there’s likely a setting for you.
Skin Rejuvenation and Anti-Ageing (Collagen Production, Wrinkles, Acne, Scars)
Red light helps stimulate collagen, which firms skin and reduces fine lines. It also supports healing of acne and can fade old scars over time. Many users notice smoother skin and improved tone after regular use.
Pain Relief and Inflammation Reduction (Muscle Soreness, Joint Pain, Arthritis)
RLT can reduce inflammation and improve blood flow, which is key for managing joint pain, muscle stiffness, and general discomfort. It’s often used by athletes and those with chronic conditions like arthritis.
Wound Healing and Tissue Repair
Studies suggest red light supports faster wound healing by speeding up cell regeneration and reducing inflammation in damaged tissues. This includes everything from minor cuts to deeper tissue repair.
Hair Growth Stimulation
By increasing blood flow to the scalp and stimulating follicles, red light may promote healthier hair growth in people with thinning or early-stage hair loss.
Other Potential Benefits (Mood, Sleep, Circulation)
Red light therapy has also been linked to improved mood and better sleep. Some people report feeling calmer and more energised after sessions. It may also help regulate your body clock and boost circulation.
Determining Your Optimal Red Light Therapy Frequency
There isn’t one perfect schedule for everyone. Your ideal red light therapy timetable depends on multiple factors.
The "It Depends" Factor: Why Frequency Varies
Your goals, skin type, and the device you’re using all play a role in how often you should have a session. Some conditions respond quickly, while others require more frequent use over time.
Individual Goals and Conditions (Skin, Pain, Recovery, Hair Growth)
If you're targeting skin improvement or hair growth, you might only need a few sessions per week. For managing pain or aiding recovery, daily sessions may offer quicker relief.
Device Type and Intensity (Professional vs. At-Home Devices, mW/cm²)
Professional-grade red light therapy beds and panels are stronger and cover more surface area. At-home devices work well too but often need longer or more frequent sessions due to lower intensity.
Individual Response and Skin Sensitivity
Some people see benefits fast, while others take longer. Sensitive skin may need shorter sessions or more rest days in between. Listen to your body and adjust accordingly.
General Recommendations for Different Applications
Here’s a general guide based on common goals.
For Skin Rejuvenation & Anti-Ageing
Start with three to five sessions a week. After a month, reduce to one to three times a week for maintenance.
For Pain Relief & Muscle Recovery
Use daily during flare-ups or intense training periods. Then taper down to three to five times a week for upkeep.
For Wound Healing & Chronic Conditions
Daily or near-daily sessions can help kickstart healing. Use five to seven times a week initially, then reduce as symptoms improve.
For Hair Growth
Aim for three to five sessions per week for several months. Consistency is key.
Session Duration: How Long Should Each Session Be?

Time matters, but it’s not all about going longer.
General Guidelines
Ten to twenty minutes per session is usually enough. Short, consistent use tends to beat long, occasional blasts.
Adjusting Duration Based on Device Power and Distance
If your panel or bed has higher irradiance (power output), you might need less time. Always check the manual and keep the right distance from your skin.
Maximising Results and Ensuring Safety
It’s not about blasting yourself with light — it’s about doing it right.
The Importance of Consistency Over Intensity
Sticking to a routine works better than cranking up the power. Your body benefits more from steady support than from sporadic overload.
Avoiding the "Biphasic Dose Response" (Too Much Can Be Detrimental)
Using red light too often or for too long can reduce its effects. More is not always better — balance is key.
Setting Up Your At-Home RLT Schedule
Getting into a rhythm makes it easier to stick with your routine.
Integrating RLT into Your Daily Routine
Try it after a workout, just before bed, or while doing your skincare. Making it a habit helps you stay consistent.
Tips for Staying Consistent
Set reminders or pair it with another daily ritual, like brushing your teeth. Even brief sessions can lead to visible results when done regularly.
Important Safety Considerations and Best Practices
Stay smart while glowing.
Starting Slowly and Monitoring Your Body's Response
Ease in, especially if you’ve never used red light before. Watch for irritation or redness, and scale back if needed.
Following Manufacturer's Guidelines
Read the instructions. Each device varies in strength and settings, so stick to what the maker recommends.
Eye Protection Recommendations
Red and near-infrared light can affect your eyes. Use goggles or keep your eyes closed, especially when using high-powered panels.
When to Consult a Healthcare Professional (Pre-existing Conditions, Medications)
If you have health conditions or take medication, speak to your GP before starting. RLT is generally safe, but it’s best to be cautious.
How Long Until You See Results?
Most people begin noticing changes within a few weeks. Skin may look brighter, and pain may lessen after consistent use.
Expectation Setting for Visible Improvements
For deeper issues like joint pain or hair growth, give it at least two to three months. Regular sessions add up over time — patience pays off.
