Thérapie par la lumière rouge (RLT) is usually thought of as a safe, non-invasive and painless treatment, but it still needs to be used correctly to avoid potential risks.
【Safety Precautions】
1. Wear something to protect your eyes.
You must wear goggles: Feu rouge (especially near-infrared light) may damage the retina, and even closing your eyes cannot completely block strong light.
Avoid looking directly at the light source: Do not look directly at the LED panel with your eyes open during treatment.
2. Problems with the skin and photosensitivity
Medicines and skin care products that react to light Some medicines, like antibiotics (tetracyclines), retinoic acid and some antidepressants, can make your skin more sensitive to light. Donc, you should speak to your doctor about this.
This product should be used carefully by patients with skin diseases, such as lupus erythematosus or photosensitive dermatitis, as it may make their symptoms worse.
3. How often and for how long you should be treated
Avoid overuse: You should try one treatment, which will take 10-20 minutes, and you should do it 2-5 fois par semaine. Using too much of this product can make your skin dry or red.
Adjust the settings to match the strength of the device: The energy of home devices and medical-grade phototherapy beds is different, so you need to follow the instructions.
4. People in some groups need to be careful.
If you are pregnant, please read this. There is not enough research yet, so it is better not to use abdominal irradiation.
Epilepsy patients: If you see a bright flash of light, you could have a seizure. If you do, you should see a doctor.
Cancer patients: Try not to use radiation on the area where the tumour is, as this may change how the cells work.
[Possible side effects] Red light therapy has few side effects, but some people may experience the following:
1. Slight skin reactions
Short-term redness or dryness: It’s like a mild sunburn, but it will get better after a few hours. Just make sure you moisturise more.
Itching or tingling: If you are sensitive to light or have a skin condition, you may need to stop your treatment.
2. Do you get headaches or feel tired eyes?
The problem could be caused by goggles that don’t fit, or by the light being too strong. It is recommended that you adjust the light intensity and rest.
3. Pigmentation (this is a rare condition).
If people with dark skin use it for a long time and in large amounts, it can make pigmentation worse, so they need to use it less often.
[Safety recommendations]
✅ Test before first use: Put a small bit of skin from an arm or something like that under water for 24 hours to see how it reacts.
Make sure your skin is clean and dry. Avoid cosmetics, perfumes and similar products that affect light absorption.
Choose standard equipment. Avoid low-quality, ineffective LED lights. Look for FDA or CE certification to make sure that the lights are good quality.
Summary
Red light therapy is very safe, and side effects are mostly mild and short-lived. If you use it correctly, the risk is very low, but some people (like pregnant women and people with skin conditions that make them sensitive to light) should speak to a doctor before use. If it still bothers you after a while, stop using it and see your doctor.
