In this blog post, we're answering your most common questions about LED therapy, from session duration to expected outcomes. Let's dive in!


LED Therapy FAQs: Answering Common Questions

1. What Is LED Therapy?

LED therapy (also known as light therapy or phototherapy) uses different wavelengths of light to target specific concerns in the body.

These wavelengths penetrate the skin and trigger cellular responses such as collagen production, inflammation reduction, and increased circulation.

2.  Does red light therapy work?

Yes, red light therapy (RLT) is effective for various applications, including pain relief, enhanced circulation, and skin rejuvenation.

Its effectiveness can depend on the specific condition being treated, the parameters used (wavelength, intensity, duration), and individual responses.

Studies have shown that RLT can help with reducing wrinkles, improving skin texture, and accelerating wound healing​

3.  What does red light therapy do?

Red light therapy works by stimulating cellular activity through the promotion of ATP production, enhancing cellular functions and repair.

This can lead to improved skin tone and texture, reduced inflammation, and pain relief for conditions like arthritis and muscle soreness.

The therapy boosts collagen production and increases blood flow, which contributes to its rejuvenating effects​.


4. What Are the Different Colors of LED Light?

Different colors of LED light have specific benefits:

  • Red light: Stimulates collagen production, aids in wound healing, and improves skin elasticity.
  • Blue light: Targets acne-causing bacteria and reduces inflammation.
  • Green light: Helps with hyperpigmentation and uneven skin tone.
  • Yellow light: Reduces redness and soothes sensitive skin.
  • Purple light: Combines red and blue light for anti-aging and acne-fighting benefits.
  • Orange light: Promotes skin revitalization and energy production.
  • Infrared light: Penetrates deep into the skin and muscle tissue, aiding in pain relief and tissue repair.

5. How long does a red light therapy session last?

LED therapy sessions are relatively quick, typically lasting between 10 and 30 minutes. The duration may vary depending on the specific treatment and the area being targeted.

6. How often should I use red light therapy?

The recommended frequency of LED therapy sessions varies depending on the treatment goals.

For most concerns, starting with 2-3 sessions per week is common, and then adjusting the frequency based on your progress.

7. Is LED & red light therapy safe?

Red light therapy is generally considered safe, non-invasive, and has minimal side effects. The side effects, if any, are usually minor and temporary, such as skin redness. It offers a cost-effective alternative to more invasive treatments and is suitable for all skin types and tones​

8. What can I expect during a session?

During an LED therapy session, you'll relax while the light is applied to the targeted area. Most people find the experience pleasant and relaxing.

The light itself is gentle and does not cause discomfort. Some people may feel a slight warming sensation depending on the treatment.

9. What Results Can I Expect?

The results of LED therapy can vary depending on the treatment goals. For skin concerns like acne and aging, you may start to notice improvements after a few sessions.

For more significant changes, such as scar reduction, it may take several weeks to see noticeable results. Consistency is key for optimal outcomes.

10. Can I Combine LED Therapy with Other Treatments?

Absolutely! LED therapy can be combined with treatments like facials, chemical peels, microneedling, and more to enhance results.

For example, red light therapy can boost collagen production after microneedling, while blue light can complement acne treatments.

11.  What is the difference between red light therapy and infrared therapy?

Red light therapy and infrared therapy differ primarily in their wavelengths and depth of penetration. Red light therapy typically uses wavelengths between 620-700 nm, which are effective for surface-level treatments such as skin issues and inflammation. Infrared therapy uses longer wavelengths (700-1000 nm) that penetrate deeper into tissues, making it suitable for treating deeper-seated conditions like chronic pain and muscle recovery​

12. What should I do before and after a red light therapy session?

Before a session, make sure your skin is clean and free of makeup or other products.

It's also important to use sunscreen daily, as LED therapy can make your skin more sensitive to the sun.



13. Is red light therapy the same as infrared saunas?

No, red light therapy and infrared saunas are different treatments. Red light therapy uses specific wavelengths of light to achieve therapeutic effects, while infrared saunas use infrared heat to warm the body, promoting relaxation and detoxification through sweating.

Each serves unique purposes and can complement each other when used in conjunction.

14. Does red light therapy work for pain?

Yes, red light therapy can be effective for alleviating pain by improving circulation and reducing inflammation. It has been used successfully to treat various types of pain, including musculoskeletal and joint pain, helping to accelerate healing and reduce discomfort​.

The red light lab has an array of devices for pain and targeted treatments, including a knee/elbow pad, neck brace, headband, hand glove and more. 

15. How to use red light therapy at home?

Using red light therapy at home involves selecting a reliable device, placing it near the targeted area, and following the manufacturer’s instructions. Typically, this involves 20-minute sessions with direct skin exposure for optimal results. Consistent use is key to achieving the best outcomes

There are many at-home LED therapy devices available for purchase.Our devices will provide benefits when used consistently. Be sure to follow the instructions for safe and effective use.
