Understanding potential side effects, safety considerations, and when to stop using LED light therapy.
LED light therapy can be beneficial for various skin concerns when used correctly.
Key takeaways:
LED face masks are generally considered safe for most people when used as directed, but some users may experience mild side effects like temporary redness, dryness, or eye sensitivity. Serious side effects are rare, but it's important to understand potential risks and when to stop use.
Some people experience mild redness immediately after a session, which typically fades within 30 minutes to a few hours. This is usually normal and indicates increased blood flow to the area.
When to be concerned: If redness persists for more than 24 hours, becomes painful, or is accompanied by swelling, stop use and consult a dermatologist.
LED light therapy can sometimes cause temporary dryness, especially if you're using the mask frequently or have naturally dry skin. This usually resolves with proper moisturising.
Prevention: Always moisturise after LED sessions, and consider reducing frequency if dryness persists.
Bright LED lights can cause eye strain or sensitivity, particularly with blue light wavelengths. This is why most masks include eye protection or recommend keeping eyes closed.
Prevention: Always use eye protection (goggles or keep eyes closed), and avoid looking directly at the LEDs.
Some people may become more sensitive to sunlight after LED sessions, though this is less common than with UV light therapy. If you notice increased sun sensitivity, reduce frequency or avoid sun exposure immediately after sessions.
Bright lights can trigger headaches or migraines in sensitive individuals. If you have a history of migraines, start with shorter sessions and monitor your response.
Rarely, some people may develop irritation, rash, or allergic reactions. This could be due to:
Action: Stop use immediately if you develop a rash or persistent irritation.
Stop using your LED mask and consult a healthcare provider if you experience:
If you're taking medications that increase photosensitivity (e.g., certain antibiotics, acne medications like isotretinoin, or some antidepressants), consult your doctor before using LED masks. These medications can increase your risk of adverse reactions.
If you have active eczema, rosacea flare-ups, or other inflammatory skin conditions, LED therapy may help some people but worsen others. Start cautiously and monitor your skin's response.
If you have eye conditions or have had recent eye surgery, consult an ophthalmologist before using LED masks, especially those with blue light.
Current evidence suggests LED light therapy is safe for long-term use when used appropriately (2–3x/week). However, there's limited research on very long-term use (years), so it's wise to take periodic breaks and monitor your skin.
LED masks use non-ionising light (unlike UV light) and are not associated with skin cancer risk. However, if you have a history of skin cancer or are at high risk, consult your dermatologist before use.
Brief exposure is unlikely to cause permanent damage, but you may experience temporary eye strain or sensitivity. If you experience persistent eye discomfort or vision changes, consult an eye care professional.
In rare cases, LED masks can cause irritation that temporarily worsens acne. This is more likely with overuse or if you have very sensitive skin. If your acne worsens, reduce frequency or stop use and consult a dermatologist.
