Is Red Light Therapy Safe? Let’s Find Out!

Red light therapy (RLT) has gained a lot of attention for its potential benefits, from reducing wrinkles and acne to relieving pain and inflammation. But one big question remains: Is red light therapy actually safe? Let’s break down the science, risks, and safety tips to help you decide if it’s right for you.

What Is Red Light Therapy?

Red light therapy uses low-level wavelengths of red or near-infrared light to stimulate cell repair and improve skin health. It’s commonly used in:

• Skincare (reducing wrinkles, fine lines, and acne)
• Pain relief (helping with muscle recovery and joint pain)
• Healing (speeding up wound and tissue repair)

Unlike UV light, red light doesn’t damage the skin. Instead, it boosts collagen production and reduces inflammation without causing burns or irritation.

Is Red Light Therapy Safe to Use?

1. No Harmful UV Rays

Red light therapy doesn’t emit UV radiation, so there’s no risk of sunburn or skin cancer.

2. Gentle on Skin

Most people tolerate red light therapy well, with little to no side effects. Unlike laser treatments or chemical peels, it’s non-invasive and pain-free.

3. Safe for Most Skin Types

Red light therapy is suitable for all skin tones and types. However, people with light sensitivity or certain medical conditions should consult a doctor before using it.

4. Eye Protection is Recommended

While red light therapy isn’t harmful to the eyes, some people find it uncomfortable. If your device is very bright or emits near-infrared light, wearing protective goggles is a good idea.

5. Overuse Can Cause Minor Side Effects

Using red light therapy too frequently or for too long may lead to temporary redness, irritation, or dryness. Stick to the guidelines to avoid overuse.

Who Should Avoid Red Light Therapy?

While red light therapy is generally safe, certain people should use caution:

• If you have photosensitivity – Some medications and medical conditions make skin more sensitive to light.
• If you have a history of skin cancer – Talk to your doctor before using any light therapy device.
• If you’re pregnant – There’s limited research on red light therapy during pregnancy, so consult a healthcare provider first.

How to Use Red Light Therapy Safely

If you’re ready to try red light therapy, here’s how to do it safely:

1. Choose an Certified Device

Look for red light therapy devices that are certified (Health Canada, FDA, FCC, CE, ROHS, ISO, etc) to ensure they meet safety standards. All Kivo products are certified.

2. Follow the Instructions

Use your device as directed to prevent irritation or overexposure.

3. Wear Eye Protection if Needed

If your device is very bright, wear protective goggles to avoid discomfort.

4. Be Patient with Results

Red light therapy isn’t instant—most people see results after 4–8 weeks of consistent use.
