At Greentoes North in Tucson, Arizona, your well-being is our top priority. Many of our guests have questions about the safety of red light therapy (RLT), and we want you to feel confident and informed. Red light therapy uses gentle, non-invasive low-level red or near-infrared light to support your body’s natural healing processes. Unlike tanning beds or sunlight, RLT has no ultraviolet (UV) rays, so it won’t burn your skin or raise skin cancer risks.
We’ll explore common safety concerns clearly and provide reliable information backed by reputable health sources, helping you use RLT safely and comfortably.
Safety and Side Effects
Is red light therapy safe for everyone?
For most healthy individuals, RLT is safe when used as recommended. Dermatologists frequently recommend RLT for improving skin conditions because it does not contain UV rays, avoiding the risk of skin cancer or burns (American Academy of Dermatology). However, if you have certain medical conditions, such as lupus or other conditions that make your skin sensitive to light, or if you are taking medications like antibiotics that increase light sensitivity, consult your healthcare provider before use.
What are the side effects of red light therapy?
Side effects are typically mild and temporary, including slight redness or warmth on the treated area. Individuals with very sensitive skin may experience minor dryness. Serious side effects, such as burns or blisters, are rare and usually result from misuse, like sessions exceeding recommended times or using damaged equipment. To avoid side effects, always follow the manufacturer’s instructions closely.
Example:
- Safe use: 10-20 minutes per area, 3-5 times weekly.
- Unsafe use: Falling asleep under the device for 30+ minutes.
Can you overdo red light therapy?
Yes. Longer sessions won’t yield faster results and might irritate skin. Treat red light therapy like watering a plant: moderate amounts regularly are ideal; excessive amounts at once cause stress. Follow your device’s recommendations and allow rest days between sessions for best results.
Does red light therapy cause skin burns?
When used correctly, RLT does not cause skin burns. Issues arise from the misuse or damage of equipment. Use reputable FDA-cleared devices, maintain proper distance, and stick to recommended time limits. If your skin feels uncomfortable or overly hot, stop the session immediately.
Contraindications and Medical Conditions
Who should avoid red light therapy?
If you have lupus, a photosensitive condition, or are taking medications that make your skin sensitive to sunlight (such as antibiotics or retinoids), consult your doctor first. People with epilepsy should only use flicker-free devices approved by their neurologist. Individuals with active cancers should never apply RLT to tumor areas without oncology guidance. Finally, avoid RLT during active infections or fevers until you’ve fully recovered.
Is red light therapy safe for cancer patients?
While RLT is used medically to alleviate side effects like chemotherapy-induced mouth sores (MD Anderson Cancer Center), it should never be directly applied to active tumors without an oncologist’s approval. Always seek medical advice before using RLT if you have or have had cancer.
Can people with epilepsy use red light therapy?
Individuals with epilepsy should use caution. Only use flicker-free, medical-grade devices. Before beginning, discuss with your neurologist and start with brief sessions under supervision. Stop if you experience unusual symptoms.
Is red light therapy safe for diabetics?
Yes, RLT is generally safe for individuals with diabetes and may help support circulation and healing. Consult your healthcare provider first if you have diabetic wounds or neuropathy. Never replace prescribed diabetes treatments with RLT.
Special Populations
Is red light therapy safe during pregnancy?
Research to date suggests that RLT is likely safe during pregnancy; however, further studies are needed. Medical experts recommend avoiding direct abdominal treatment. Consult your OB-GYN before treatment.
Can children use red light therapy?
Children can safely use RLT under the supervision of a medical professional. Sessions should be shorter (5-10 minutes), and protective eyewear is essential. Always get pediatrician approval before beginning sessions for minors.
Is red light therapy safe while breastfeeding?
There’s no known risk to breast milk quality or nursing babies but avoid treating the breast directly. Focus on treating other areas and consult your healthcare provider if uncertain.
Eye Health and Vision Safety
Is red light therapy safe for the eyes?
RLT does not contain harmful UV rays, but it’s bright enough to strain your eyes. Protect your eyes by closing them or using goggles during sessions.
Should you wear goggles during red light therapy?
Yes. Goggles specifically designed for RLT protect your eyes effectively. Use them during facial treatments or if your eyes may be exposed to the bright light.
Can red light therapy improve eyesight?
Emerging research suggests controlled use of specific deep-red wavelengths can improve age-related vision decline, but this is experimental. Do not attempt to self-treat eyesight with standard RLT panels. Consult an ophthalmologist if interested.
Does red light therapy damage the retina?
Properly used, RLT does not damage your retina. Direct staring into bright lights could strain your eyes, so always use goggles or close your eyes during sessions.
Myths and Misconceptions
Is red light therapy just a placebo?
Clinical research has demonstrated real physiological benefits beyond placebo effects, such as improved collagen production, hair regrowth, and reduced inflammation (Stanford Medicine). It’s effective but not miraculous.
Does red light therapy cause cancer?
No. RLT uses safe, non-ionizing light incapable of damaging DNA or causing cancer. It’s safely used in medical settings to treat certain side effects of cancer therapy.
Is red light therapy the same as tanning?
Absolutely not. Tanning involves exposure to harmful UV light, which darkens the skin and damages cells. RLT has no UV and promotes healing, not tanning.
Does red light therapy age skin faster?
No. RLT typically improves skin health by boosting collagen and reducing inflammation. Unlike UV rays, it does not accelerate the aging process.
