For most healthy adults, an LED face mask with red and near-infrared light is low risk when used as directed. The American Academy of Dermatology says that in the short term red light therapy "appears to be safe", and the face trials reported mild, short-lived side effects at most. The real questions are your eyes, light-sensitising medicines and a few health conditions, which is what this guide covers.
If you want the bigger picture first, our guide to red light therapy mask benefits explains what a mask can and can't do for your skin. This article is about safety only.
Key takeaways
- Red and near-infrared LED masks have a good short-term safety record in studies; reported side effects are mild and temporary, such as discomfort, warmth or skin irritation.
- Eyes are the main concern. The published case of retinal injury from an LED face mask involved blue light, and its authors stressed keeping the eyes covered.
- Skip a mask, or ask a doctor first, if you have a light-sensitive condition such as lupus, take a photosensitising medicine, have an eye condition, are pregnant or have light-triggered epilepsy.
- "FDA cleared" means a device was found substantially equivalent to one already on the market. It tells you the device is considered low risk, not that it works for you.
- The Folliq mask is a cosmetic light device for home use. It has built-in opaque eye cups, contact and heat sensors and a 10-minute timer that switches it off.
Are LED face masks safe for your eyes?
An LED face mask is safest for your eyes when the eyes are covered and the light is red or near-infrared rather than blue. A published 2020 case of retinal damage from an LED face mask involved blue light, and its authors advise covering the eyes. Keep your eyes closed, use the eye protection the device provides, and never stare into the lit panel.
That case was published in 2020: a 37-year-old woman sought care for distorted vision a month after using a blue LED face mask, and doctors found damage to the retinal pigment layer near the centre of her vision (Kim et al., 2020). The authors concluded that prolonged blue light exposure can harm the retina and that the eyes should be covered during LED mask use. It is a single case report, so it can't tell you how common this is, but it shows why eye protection is not optional.
Red (around 630 to 660 nm) and near-infrared (around 810 to 850 nm) light carry less energy per photon than blue light, and the face studies with red and near-infrared LEDs reported few or no side effects. That does not make bright red light comfortable to look at. Near-infrared is also invisible, so a panel can be working even when parts of it look dark. The simple rule: use the eye protection the device was designed with, keep your eyes closed, and don't swap it for ordinary sunglasses. The AAD's page on red light therapy covers who should check with a dermatologist first.
On the Folliq Red Light Therapy Face Mask, the eye protection is built in. The opaque eye cups are designed to let through no more than 0.1% of the light, no LED sits within 15 mm of the eye openings, and contact sensors in three zones (forehead and both cheeks) keep the light off until the mask touches your skin. These are design specifications confirmed by our engineer, not lab measurements; production units are going to an independent lab, and we will publish that report on the product page whatever it shows.
What happened with the Neutrogena LED mask recall?
In July 2019, Neutrogena recalled its blue light therapy mask, citing a "theoretical risk of eye injury" for a small group of people with certain eye conditions and for users of medicines that increase the eyes' sensitivity to light. The company described reports of visual effects as rare, mild and transient (ABC 6, 22 July 2019).
The recall is often quoted as proof that all LED masks are dangerous. Read closely, it says something narrower and more useful:
- The light mattered. The recalled mask used blue light. Blue light is the type of light involved in the retinal case report above.
- The person mattered. The risk was described for people with existing eye conditions or on photosensitising medicines, not for everyone.
- Design matters. The same questions apply to any mask you buy: what wavelengths does it use, and how are the eyes shielded?
If you have an eye condition of any kind, ask your eye doctor before using any LED mask, whatever its colours.
What side effects do people report?
The side effects reported with red and near-infrared LED masks are usually mild and short-lived: temporary discomfort, a feeling of warmth or slight skin irritation. The AAD notes that long-term effects have not yet been studied, which is one more reason to keep to the designed session and schedule.
The trials point the same way. A systematic review of 31 randomised controlled trials of LEDs in dermatology noted few adverse events, while also flagging small sample sizes and varied study settings as limits (Jagdeo et al., 2018). In a split-face study of 76 people using 633 and 830 nm LEDs, the light sessions were "well-tolerated by all patients with no adverse effects" (Lee et al., 2007). A 2025 randomised, sham-controlled trial of a home LED mask (630 + 850 nm) in 60 adults also described the mask as safe and well tolerated (Park et al., 2025).
Two side effects deserve a closer look:
- Warmth. More power means more warmth on your face. A gentle, even warmth is normal; skin that feels hot or stays red is a reason to pause. The Folliq mask runs a fixed 10-minute session and then switches itself off. Its design specification, confirmed by our engineer, is a skin-side temperature at or below 39 °C in normal use; heat sensors lower the power at 41 °C and switch the mask off at 43 °C.
- Dark spots. The AAD notes that people with darker skin tones are more sensitive to visible light, which can cause longer-lasting dark spots, and suggests talking to a dermatologist before using an at-home device. If you have melasma or pigment spots, start with red-only mode and short sessions, and stop if any area darkens.
Stop a session and check with a doctor if you get blurred or distorted vision, eye pain, a headache that keeps coming back, blistering, or a rash that doesn't settle within a few hours.
Who should skip an LED face mask or ask a doctor first?
An LED face mask is not for everyone. People with a light-sensitive condition, a photosensitising medicine, an eye condition, light-triggered epilepsy, pregnancy, or broken or undiagnosed skin on the face should skip it or ask a doctor first. The table below sums up who should pause and why, based on the AAD, FDA and our own product guidance.
| Situation | What to do | Why |
|---|---|---|
| Lupus or another light-sensitive condition | Skip, unless your dermatologist says otherwise | The AAD notes that light-sensitive conditions such as lupus can worsen with red light exposure |
| A medicine that makes you sensitive to light | Ask your pharmacist or doctor first | Many common medicines can cause photosensitivity (see the next section) |
| An eye condition, or a history of retinal problems | Ask your eye doctor first | The 2019 mask recall named people with certain eye conditions as the group at risk |
| Light-triggered (photosensitive) epilepsy | Skip, or ask your neurologist first | Folliq's product guidance lists light-triggered conditions as a reason not to use the mask |
| Pregnancy | Skip for now | There is no research establishing safety in pregnancy, so we would rather not imply an all-clear |
| Melasma, or a tendency to dark spots | Ask a dermatologist; start with red only and short sessions | Visible light can deepen pigmentation, especially in darker skin tones |
| A suspicious mole, an undiagnosed lesion or skin cancer on the face | See a doctor before using any light device | A changing lesion needs a diagnosis first |
| Broken, sunburned or freshly treated skin (peel, laser, injections) | Wait until it has healed, or ask the person who treated you | Irritated skin reacts more easily |
| Children and teenagers | Not for children | Masks are designed and sized for adult faces |
Our safety and contraindications page lists the same rules for every Folliq device, including the hair devices.
Which medicines and skincare make skin sensitive to light?
Photosensitivity is a chemically induced change in the skin that makes it react more strongly to light. According to the FDA, it can be triggered by medicines taken by mouth or injected and by products applied to the skin, and not everyone who takes these medicines will react. If your leaflet mentions sun sensitivity, treat that as a reason to ask before using an LED mask.
The FDA's list of medicine groups that can cause sun sensitivity includes (FDA, The Sun and Your Medicine):
- Some antibiotics: for example doxycycline, tetracycline, ciprofloxacin and trimethoprim.
- Oral retinoids: isotretinoin and acitretin.
- Some diuretics: for example hydrochlorothiazide and furosemide.
- Some anti-inflammatories (NSAIDs): for example ibuprofen, naproxen and ketoprofen.
- Phenothiazines and psoralens, such as chlorpromazine and methoxsalen.
- Some antifungals, antihistamines, statins, diabetes medicines and oral contraceptives or estrogens.
- Alpha-hydroxy acids (AHAs) in cosmetics.
Most of these warnings were written with sunlight in mind, which includes UV. Red and near-infrared LEDs don't emit UV, but there is little research on how each medicine interacts with them, so the cautious step is a quick question to your pharmacist. Never stop a prescribed medicine to make room for a beauty device. Herbal remedies count too: our safety page lists St John's wort among the products to ask about.
How do you use an LED face mask safely?
Use an LED face mask on clean, bare skin, with your eyes closed behind the eye protection, for the full timed session and no more. Start with a short first session, keep to the schedule the device was designed for, and stop if your eyes or skin complain. These steps apply to most masks.
- Read the leaflet first. Check the wavelengths, the session length and the list of who should not use it.
- Do a short first session. On the Folliq mask, try 5 minutes, then check your skin the next day before moving to the full 10 minutes.
- Start with bare skin and closed eyes. No makeup, sunscreen or serum under the mask, and keep your eyes closed behind the eye cups for the whole session.
- Let the timer decide. Don't run sessions back to back. Light research describes a biphasic response, meaning more light past a certain point adds no benefit and can reduce it (Huang et al., 2009). On the Folliq mask, one 10-minute session per sitting is the whole routine, and by design specification, confirmed by our engineer, the controller allows at most one full session every 6 hours.
- Keep to the weekly rhythm. For the Folliq mask that is three evenings a week; our guide on how often to use an LED face mask explains why daily use isn't needed.
- Stop if something feels wrong. Eye strain, a headache, burning or a rash that lasts are reasons to stop and ask a doctor.
Does FDA clearance mean an LED mask is safe?
FDA clearance means the FDA accepted a 510(k) submission showing the device is substantially equivalent to a device already legally on the market. The AAD explains that "FDA-cleared" means the FDA considers the device low risk, but says nothing about how well it works. Clearance is a useful safety signal. It doesn't replace checking wavelengths, eye protection and heat limits yourself.
In a 510(k), the maker compares the new device with one or more "predicate" devices and supports that comparison with data such as bench testing, electrical safety and software checks, and sometimes clinical data (FDA, Premarket Notification 510(k)). The AAD adds that the FDA clears these devices rather than approving or certifying them, so the word to look for is "cleared", together with a 510(k) number you can check in the FDA's database.
As for our own product, the Folliq mask is a cosmetic light device for home use, and what we publish is a written specification: 633 nm red and 830 nm near-infrared light, a design irradiance of 12 mW/cm² averaged across the face, 7.2 J/cm² per 10-minute session, opaque eye cups, contact sensors in three zones, heat cut-offs at 41 °C (lower power) and 43 °C (switch-off), and an automatic 10-minute switch-off. Production units will be tested by an independent lab for irradiance, eye safety and surface temperature; IEC 62471 is the international standard for the photobiological safety of lamps and lamp systems, LEDs included (IEC). We will publish that report on the product page whatever it shows, and we won't claim compliance before it exists.
Whatever mask you consider, check these five points: stated wavelengths in nanometres, no blue light near uncovered eyes, built-in eye protection or goggles in the box, an automatic timer and heat cut-off, and a return window long enough to judge it. Our guide on how to choose an LED face mask goes through every spec, and our red light face care range shows how Folliq answers each one.
FAQ
Do I need to close my eyes when using an LED mask?
Yes. Keep your eyes closed for the whole session, even when the mask has built-in eye cups. Closed eyelids plus eye protection is the safest combination, and covering the eyes is what the authors of the 2020 retinal case report recommended.
Is red light therapy bad for your eyes?
Red and near-infrared light carry less energy than blue light, and the face studies using them reported few or no side effects. Bright light of any colour is still uncomfortable to stare into, so use the eye protection your mask provides and ask an eye doctor first if you have an eye condition.
Can I use an LED face mask every day?
Follow the schedule your mask was designed for. The Folliq mask is designed for 10 minutes, three evenings a week. More light past a certain point does not add benefit, so daily or back-to-back sessions are not needed.
Are LED face masks safe for darker skin?
Red and near-infrared masks can be used on all skin tones, but the AAD notes that darker skin is more sensitive to visible light, which can cause longer-lasting dark spots. Talk to a dermatologist first if you are prone to pigmentation, start with short red-only sessions, and stop if any area darkens.
Can I use an LED mask while pregnant?
We advise against it. There is no evidence of harm, but there is also no research establishing safety in pregnancy, so Folliq lists pregnancy as a reason not to use the mask.
Is the Folliq mask a medical device?
No. It is a cosmetic light device for how skin looks. It has built-in eye cups, contact and heat sensors and a 10-minute timer, and you can try it at home for 90 days, even if used.
Try it at home, with the eye protection built in
The Folliq Red Light Therapy Face Mask uses only 633 nm red and 830 nm near-infrared light, with opaque eye cups built into the mask and a 10-minute timer. It costs $249 with free tracked shipping, a 2-year warranty and a 90-day home trial, even if used, so you can see how your skin and eyes feel with it before you decide.
The Folliq Red Light Therapy Face Mask is a cosmetic device, not a medical device, and is not intended to diagnose, treat, cure or prevent any disease. This article is general information, not medical advice. If you have a medical or eye condition, or take regular medication, ask your doctor or pharmacist before using any light device.
