How to use a red light mask: what to do during the session so it works better
Red light therapy works through blood flow, and a calm body sends more of it to your skin. Five ways to spend a mask session that help the light do its work.
A red light mask session is usually fifteen minutes of lying still while your LED face mask does its work. How you spend that time has a bearing on how much the treatment can do. If you've invested in an Omnilux, CurrentBody, Dr. Dennis Gross, or any other at-home red light therapy device, the state of your nervous system during the session is a variable worth paying attention to, and one that is easy to change.
If you own a red light therapy mask, you know how it goes. The mask goes on, the timer starts, and you lie there for fifteen minutes trying not to check your phone. Most of us end up scrolling Instagram, answering emails or running through tomorrow's to-do list in our heads. There is no harm in any of that, except that it keeps your nervous system in the one state that gives the light less to work with.
The good news is that those minutes are easy to use well, and the five ideas below need nothing you don't already have.
Why scrolling on your phone works against red light therapy
Red light therapy depends on blood flow. The light stimulates cellular activity in the dermis, but the oxygen and nutrients those cells need arrive through the blood. Good circulation to the skin gives the treatment more to work with, while restricted circulation leaves the cells switched on but undersupplied.
Stress narrows the blood vessels in the skin, and this part is well documented. Cortisol makes the vessels more sensitive to constriction, reduces the production of vasodilators like nitric oxide, and tightens the peripheral vessels that supply your face and body. Scrolling social media, reading the news or thinking about work all keep cortisol raised. Your body is lying still, but your nervous system is not resting.
The device is already doing its part. Giving it a calm body to work on is the piece most people have never been told about, and it costs nothing to add.
Five things to do during your red light therapy session
1. Breathwork during red light therapy
Box breathing (four counts in, four counts hold, four counts out, four counts hold) is the simplest way to move from sympathetic to parasympathetic dominance. A few minutes of slow-paced breathing has been shown to reduce cortisol and shift heart rate variability toward parasympathetic activity. There is no app to download and no skill to learn, since all you have to do is count.
2. Body scan meditation with your LED mask
Any guided body scan will do. Moving your attention slowly through your body, from the feet upwards, draws the nervous system into a calm and present state. Most body scans run to about fifteen minutes, which happens to be the length of most red light mask sessions, so the two fit together neatly.
3. Ambient sound or soundscape
Rain, the sea, birdsong or brown noise all work well here. Music with lyrics or a strong structure tends to wake up the thinking brain, so choose something textured and repetitive that your ears can settle into. A soundscape on its own is gentler than the active techniques above, and it is a much better companion than silence if silence makes you fidgety.
4. Deliberate stillness
Lie there with your eyes closed and let your mind wander. The boredom itself does something useful, because your brain drifts into default mode network activity, which is associated with lower cortisol and greater parasympathetic tone. If you feel the urge to pick up your phone, take it as a sign that your nervous system is still a little activated. Noticing the urge and letting it pass, even when it feels uncomfortable, is part of how the calm arrives.
5. A guided frequency routine
This is the most structured option, and the one that reaches the physiology most directly. Specific sound frequencies (binaural beats in the theta range, solfeggio tones at particular pitches) have been linked with measurable reductions in cortisol and increases in parasympathetic activity in several small studies, which are early but point the right way. A timed routine also gives you something to follow without waking the planning and problem-solving parts of your brain. The sound settles your nervous system while the light gets on with stimulating your cells.
I built the Skin Resonance "With skincare" routines for exactly this, with sound frequencies timed around a red light mask session. The free ten-minute routine is a good place to feel how it works.
A simple red light mask routine structure
If you want a plan that needs nothing beyond your LED face mask and a pair of headphones, this one is easy to remember.
Minutes 1 to 3: Put the mask on, close your eyes and take ten slow breaths, each one a little longer than the last. There is nothing to force. Let the exhale lengthen gradually until you feel your shoulders drop.
Minutes 3 to 12: Listen to ambient sound or a guided frequency routine with your eyes closed. If your mind wanders, let it, and don't worry about meditating well. All you are after is a calmer body, and a wandering mind is no obstacle to that.
Minutes 12 to 15: As the mask timer winds down, stay still and notice how your face feels, the warmth from the LEDs, the weight of the mask, the temperature of your hands. This is proprioceptive attention, and it keeps you in the parasympathetic state through the end of the session rather than snapping back to alert mode the moment the timer beeps.
None of this asks for special skills or prior experience. It is simply a decision to spend the session helping the treatment along, and after a few evenings it becomes the natural way to wear the mask.
Why a calm body gets more from red light therapy
Most red light therapy advice is about the device, which wavelength, how many nanometres, how close to hold it and for how many minutes. All of that counts, and it is worth getting right. The variable that gets almost no attention is the state of your body while the light is working. A relaxed body with open blood vessels and low cortisol gives the cellular processes the light triggers a far better environment than a stressed body with constricted vessels and raised cortisol.
Shifting that balance takes nothing complicated. The phone goes down, the breathing slows, and your nervous system gets the same fifteen minutes of care you are already giving your skin. My routines exist to make that easy, but even the breathing on its own will take you a long way.

Frequently asked
What should you do during a red light mask session?+
Breathwork, a body scan meditation, ambient soundscapes, deliberate stillness, or a guided sound frequency routine. All of these support parasympathetic activation, which dilates blood vessels and improves the delivery of oxygen and nutrients to skin cells while the light works. Scrolling your phone keeps cortisol elevated and works against the treatment.
Does using your phone during red light therapy make it less effective?+
It can. Scrolling social media, reading news, or answering emails keeps your nervous system in a sympathetic state, which constricts blood vessels in the skin. Red light therapy depends on blood flow to deliver oxygen and nutrients to the cells the light is stimulating. A stressed body with constricted blood vessels provides a worse environment for the treatment than a relaxed one.
How long should a red light mask session be?+
Most at-home red light masks are designed for 10 to 15 minute sessions. Follow your device manufacturer's recommended time. How you spend those minutes counts for as much as their length. A calm, relaxed body supports better blood flow and cellular response than a stressed, distracted one, so the session gives the light more to work with.
Does blood flow affect red light therapy results?+
Yes. Red light stimulates cellular activity in the dermis, but oxygen and nutrients reach those cells through blood. Cortisol constricts peripheral blood vessels, while parasympathetic activation dilates them. A relaxed body with good circulation provides a better environment for the cellular processes the light triggers than a stressed body with restricted blood flow.
Can you do breathwork during red light therapy?+
Yes, and it's one of the most effective ways to spend the session. Box breathing (four counts in, four hold, four out, four hold) shifts heart rate variability toward parasympathetic activity within minutes. You don't need an app or any prior experience. The breathing supports nervous system calm while the light works on your skin cells.
