As long as you know how to use your RLT devices, there shouldn’t be any trouble in using them. However, there are times when RLT can burn skin or cause irritations, especially when used the wrong way. 

Do you want to know more about the benefits and drawbacks of using RLT? If so, skim through to the end.

In general, red light therapy is quite a safe treatment. However, the effectiveness of the treatment may vary depending on how you use this treatment. 

Not following the instructions, altering the required distance, and overexposure might cause burns and skin damage. Even your best DIY red light therapy might cause burns if you don’t follow the recommendations. 

Can Red Light Therapy Cause Skin Burn? 

When used correctly, RLT is unlikely to cause side effects. Moreover, having the device turned on longer also increases the chances of skin damage. It can cause: 

• Burns
• Blisters
• Vision loss (in rare cases)

So, you should only take RLT sessions with prescribed instructions to ensure your eyes stay protected.

How Does Red Light Therapy Work?

Red light therapy devices emit red light with a low wavelength. This then penetrates deep inside the skin. 

The mitochondria inside the skin cells absorb this light and produce more ATP (the cells’ energy source).

Proponents believe this extra energy helps cells respond better to damage and rejuvenate.

Although early signs confirm the potential benefits of RLT, more evidence is required to state this claim.

Possible Good Sides And Side Effects of Red Light Therapy

Here are some of the good sides and drawbacks linked with red light therapy. 

Good Sides

1. Skin Regeneration and Repair

High-quality red light therapy can help in regenerating and repairing damaged cells. Studies have shown that RLT can enhance skin regeneration by:

• Increasing collagen production, improving skin elasticity
• Boosting fibroblast production, aiding in collagen and tissue fiber generation
• Enhancing blood and tissue cell circulation
• Protecting cells from damage
• Increasing mRNA levels, stimulating cell activity
• Reducing fine lines and severe wrinkles

1. Acne Improvement

Research indicates that RLT can help control acne by affecting the sebaceous glands. These glands produce sebum, which can clog pores and cause acne. 

RLT, often combined with blue light therapy, penetrates the skin to reduce sebum production, irritation, and inflammation.

1. Wound Healing

RLT can accelerate wound healing by:

• Reducing inflammation
• Stimulating new blood vessel formation (angiogenesis)
• Increasing beneficial fibroblasts
• Boosting collagen production

1. Hair Growth

Studies show that RLT can improve hair density and prevent hair loss. Regular therapy with wavelengths of 665 nanometers and 808 nanometers is recommended for better results.

Red Light Therapy Side Effects

1. Eyestrain and Discomfort

Excessive exposure to light therapy can result in eyestrain and discomfort. 

People sensitive to the eyes are advised to wear protective eyewear, like some special glasses.

1. Headaches

In rare cases, an individual may suffer from headaches due to exposure to bright light.

Monitoring the brightness and duration of the sessions can build up a tolerance to light.

1. Nausea

An individual can rarely feel nauseous under or due to light therapy. This can occur when the level of light is too high.

This effect can be reduced by lowering the light intensity and shortening the duration of the session. Continued nausea should be medically investigated for underlying problems.

1. Manic or Hypomanic Issues

In some patients, light therapy can cause manic or hypomanic symptoms. Close medical supervision is necessary, and you may need to pause the treatment in case of manic symptoms. 

5 Ways You Can Prevent Skin Burn From Red Light Therapy

Although RLT is safe to use, sometimes skin burns due to inappropriate use can result in serious discomfort. Here’s how you can prevent your skin burns.

1. Short Sessions

Shorten the initial sessions so your skin gets used to the therapy, then gradually increase as your body gets used to it.

2. Monitor Skin Reactions

Look at how your skin reacts during and right after each session. If you notice redness, irritation, or discomfort, discontinue the treatment and seek the help of a healthcare professional.

3. Protective Eyewear 

The light from RLT devices can cause harm to your eyes, especially if you don’t wear protective eyewear.

So, use only those protective goggles or eyewear that are recommended by your manufacturer or seller.

4. Keeping the Right Distance

Maintain the right distance, as you need to do so to avoid exposing yourself to the light too much. Plus, if you are far away from the RLT device, the light might not penetrate the skin for effective treatment. 

5. Preparing Your Skin

Make sure your skin surface is clean and free of products that enhance sensitivity and make one have reactions to light.
