An LED mask rests on your face and lights only that; a red light panel stands 8–50 cm from your skin and can also reach your neck, chest or body. Panel sessions last 10–30 minutes, at most 30 minutes a day on the same area. Smart Series panels measure 132–152 mW/cm² at 15 cm.
What's the difference between an LED mask and a red light panel?
A mask is shaped to fit the face, so what it covers is fixed. What a panel covers depends on its size and how far away you sit. Each LED in a Smart Series panel has a 30° beam, so the light fans out as it travels: step back and the lit area grows; move closer and the light concentrates on a smaller patch. Our article on how to set the right distance explains how to choose yours.
Size does the rest. The Smart Small, 30 cm tall on a table stand, covers the face, neck and shoulders; the Smart Medium, twice as tall, also reaches the back or legs, on a floor stand or wall mount.
How much light reaches your skin from a mask or a panel?
That's irradiance, measured in mW/cm², and it only means something next to the distance it was measured at. The Smart Series figure above is a spectrometer reading at 15 cm; we don't estimate values for other distances.
Check whether a mask comes with such a figure at all. A 2026 study measured four cosmetic LED masks: the makers' documents didn't say how much light the masks emit at each wavelength, and the measured irradiance varied markedly from mask to mask, so similar recommended session lengths delivered very different amounts of light (Baeza-Moyano et al.).
So whichever you choose, ask the seller three things: the measured irradiance, how it was measured, and at what distance. Ask about the wavelengths too. Smart Series panels have two separately controlled channels: red (610, 630 and 660 nm) reaches the layers near the surface of the skin, near-infrared (810, 830 and 850 nm) reaches deeper layers. Our article on near-infrared vs red light explains the difference.
What does research explore about masks and panels?
Research has looked at both face masks and large-area light devices, mostly for the look of the skin. In a 2025 trial, 60 adults used either a home LED mask (630 and 850 nm) or a sham device for 16 weeks; from week 8, independent raters scored the fine lines at the outer corners of the eyes as improved compared with the sham group (Park et al.). In a 2014 controlled trial with 136 volunteers, the groups that used large-area, full-body light devices (polychromatic lamps, not LEDs) twice a week for 30 sessions showed smoother skin and higher collagen density, measured by ultrasound, than the controls (Wunsch & Matuschka).
These are results in the study participants, with the devices each study used, not a promise for any product. A 2018 systematic review of 31 randomised trials of LED light on the skin also noted that some were small (fewer than 20 participants) and that settings varied between them (Jagdeo et al.), one more reason why measured settings matter.
Which is more comfortable to use?
A mask is hands-free: you can sit back or read while it's on. But it touches your face, so it needs regular cleaning, especially after skincare products or sunscreen, and some people find it warm, heavy on the nose or enclosed.
Nothing touches your skin with a panel: you sit or stand in front of it, and the same setup works for your face one day and your back the next. In return, it needs a little more room and a fixed spot.
A mask puts the LEDs right next to your eyes, so follow its maker's instructions. With our panels: Close your eyes or wear the goggles; there's a pair in every box. Our article on whether red light therapy is safe for your eyes goes into more detail.
LED mask or red light panel: which one suits you?
Choose a mask if your routine is about your face only, you have little space, or you want something to take travelling.
Choose a panel if you want more than your face in one session, may want to use it on your back or legs later, or will share it with someone at home.
In our range, price follows size: the larger the panel, the more it lights at once and the higher its price band. You can compare our models in the panel collection. They're made by a partner manufacturer to RedLightMed's specification and European (CE) requirements, and every unit is checked in Hungary.
It isn't recommended for children under 12, while breastfeeding, with epilepsy, with known tumours or metastases, or if you're sensitive to light. During pregnancy, only after talking to your doctor.
