Summary
Red light therapy – also known as photobiomodulation – is a non-invasive treatment that uses red, infrared, and near-infrared light to support your skin, muscle recovery, and overall sense of wellness. Used consistently, it’s linked to firmer, healthier-looking skin, faster recovery after exercise, and better rest. In this guide, we cover the proven and emerging red light therapy benefits, how the treatment works, and why full-body beds like those available at The Tanning Shop Ireland have the edge over at-home devices.
If you’ve been curious about red light therapy but aren’t sure what it actually does, you’re in good company – it’s one of the questions our team gets asked most. Whether you’re seeking calmer skin, quicker recovery after a workout, or just fifteen minutes to yourself, here’s what the evidence actually says about each benefit and how it could support your wellness routine.
How Does Red Light Therapy Work?
It starts at a cellular level. Mitochondria are the tiny structures inside almost every cell in your body that produce energy – think of them as each cell’s own power plant. When red, infrared, and near-infrared light penetrates the skin, mitochondria absorb the wavelengths and respond by producing more ATP (adenosine triphosphate), the fuel your cells use to repair and regenerate themselves.
That extra energy is what sits behind most of the red light benefits in this guide, from skin rejuvenation to muscle recovery. It’s a gentle, cumulative process rather than an instant one, which is why consistency matters when it comes to red light treatments.
Red Light Therapy for Skin Health
There’s a lot of chat in the beauty and wellness sphere about how red light can make you look younger. And there’s actually strong research to suggest it can. Now, we’re not claiming it can turn back time, but many studies note a visible reduction in wrinkles and firmer, more youthful-looking skin with regular sessions. That’s mainly down to red light’s ability to increase collagen and elastin production – two key factors for keeping skin bouncy and healthy.
With consistent sessions, here are some of the red light therapy skin benefits you could notice:
- Firmer, more elastic-feeling skin – red light encourages fibroblasts (the cells that produce collagen and elastin) to work harder, which helps skin feel firmer and more youthful.
- Fewer fine lines and wrinkles – by boosting collagen and accelerating repair, red and near-infrared wavelengths can noticeably improve fine lines and rough texture after a course of sessions.
- A more even tone – improved circulation may help to reduce redness, blotchiness, and hyperpigmentation with regular use.
- Calmer breakouts – red light is also used by dermatologists as a complementary approach to acne, generally alongside your usual skincare rather than instead of it. It helps soothe active flare-ups and minimise acne scarring.
- Support for skin conditions – red and near-infrared light can calm the kind of inflammation involved in conditions like eczema, psoriasis, and rosacea. If you have a diagnosed skin condition, it’s always worth checking with your dermatologist first and letting our team know before you book.
None of this happens after one visit. Most of the research on skincare benefits comes from multiple sessions a week over around 8-12 weeks, so think of red light therapy as a routine rather than a one-off treat. It’s also worth pairing sessions with skincare products that support the same goals – our red light therapy products are designed to work alongside your sessions to maximise results.
Red Light for Muscle Recovery and Pain Relief
Recovery and pain support is the other area with genuinely strong evidence behind it, and it works through a few connected mechanisms:
- Better circulation – red light is linked to increased blood flow to the treated area, helping deliver oxygen and nutrients where your body needs them most.
- Reduced inflammation – the same anti-inflammatory response that helps skin also applies to sore or overworked muscles and joints.
- Faster healing – that extra cellular energy from the mitochondria response gives muscle tissue a head start on repairing itself. It also helps speed up healing of wounds and surgical scars.
- Eases DOMS – if you’ve ever struggled to walk down stairs the day after a big gym session, that’s delayed onset muscle soreness (DOMS). Many clients use red light therapy specifically to take the edge off it.
This isn’t a treatment reserved for athletes, either. Plenty of our customers use red light therapy simply because their job or routine leaves them stiff and tired, and a session gives their body a chance to catch up. Timing is flexible too: a session before activity can help you feel warmed up and ready to move, while a post-workout treatment gives tired muscles a head start on repair.
Red Light for Relaxation and Sleep
Light is one of the strongest cues your body uses to set its internal clock, and red light behaves very differently to the blue light most of us stare at all evening from our phones, laptops, and TVs. Where blue light suppresses melatonin – the hormone that signals to your body that it’s time to sleep – red light can have the opposite effect.
Some research suggests that evening exposure to red light may actually increase natural melatonin production, helping support better quality, more restful sleep. It’s also connected with regulating your body’s natural circadian rhythm, which helps to align your sleep-wake cycle so you’re not just getting better sleep, but better sleep at the times you need it most.
A lot of our customers treat their session as a proper wind-down: fifteen minutes with nowhere to be and nothing to look at, at the end of a long day. It won’t replace good sleep habits on its own, but as part of an evening routine, it’s a simple way to build in a moment of calm.
Red Light Therapy for Hair Loss and Scalp Health
Now, this one is a growing area of research, but it looks to have some real potential.
The same mechanism that supports skin repair applies to your scalp, too. Better circulation means more oxygen and energy reaching hair follicles, which can stimulate hair growth. Recent studies have linked red light therapy to regrowth and increased hair thickness in people with hormonal and hereditary hair loss.
Though it won’t regrow a full head of hair or cure hair loss, early indicators suggest regular sessions alongside prescribed medications could improve results. If you’re dealing with hair loss, it’s worth talking to your GP or a dermatologist first.
Red Light Therapy for General Well-being
The benefits of red light therapy go beyond skin and muscles. Many of our customers keep coming back because of how the sessions make them feel.
- A noticeable energy lift – less of that dragged-out, flat feeling, and more get-up-and-go through the rest of the day.
- A real sense of calm – red light therapy is linked to lower stress hormones and a lift in the “feel-good” chemicals your body makes naturally, like serotonin and dopamine. Customers often describe walking out feeling noticeably lighter than when they walked in.
- A clearer head – many people find they think more sharply and feel more focused after a session, without the fog that a stressful day can bring on.
Part of that is physical, and part of it is just the value of time that’s entirely yours, in a space in which you can truly unwind and clear your mind.
Red Light Therapy Bed vs At-Home Devices
It’s a fair question: are red light therapy bed benefits actually better than at-home results? A home device is genuinely convenient – no travel, no salon booking, use it whenever suits you. But convenience is really the only place it wins:
- Full-body coverage – our bed treats your entire body in one sitting; the vast majority of home devices are small, designed for targeted application, so you’re left moving a panel or mask around yourself if you want to focus on more than one area.
- More LEDs, wider wavelength range – our advanced bed uses tens of thousands of LEDs across five clinical wavelengths for deeper, more even coverage; most home devices use far fewer LEDs across a narrower range, which is the main reason results can take longer and feel less consistent.
- Time – a full-body salon session is typically quicker overall than working a smaller device across multiple areas one at a time. Because at-home devices aren’t as powerful, they tend to have longer recommended session times as well.
- Consistency and guidance – a booked appointment is harder to skip than a device sitting in a drawer, and our team is on hand to advise on frequency to create a personalised outline that you’ll actually stick to.

FAQs
Does red light therapy actually work?
There’s real, growing evidence behind it, especially for skin appearance and muscle recovery – though, like most wellness treatments, results vary from person to person and build up with regular sessions.
What does red light therapy help with?
The best-supported red light benefits are skin health (firmness, texture, tone, and some support for acne, eczema, and psoriasis), muscle recovery, and general relaxation. Some people also use it for hair and scalp health, support with chronic pain, and post-surgical healing.
How often should I do red light therapy to see results?
Most people see the best results from 3 to 6 sessions a week, particularly in the first few weeks. Once you’re seeing the red light therapy benefits you’re after, we may suggest you drop down to a maintenance routine of one or two sessions a week.
Is red light therapy the same as using a sunbed?
No. Red light therapy uses red and near-infrared light rather than UV light, so it works through a different mechanism and isn’t used for tanning. If you’re also interested in tanning, our team can talk you through the options available at your local salon.
What's the difference between a red light therapy bed and an at-home device?
Our bed treats your whole body in one session, using far more LEDs across a wider wavelength range than most home devices offer, which is why coverage and consistency tend to be better in-salon. Home red light therapy devices are more convenient for day-to-day use but usually cover only one area at a time.
Where can I try red light therapy near me?
Red light therapy is available at selected The Tanning Shop salons across Dublin and County Wicklow, currently Dundrum, Greystones, and Tallaght. Visit our store locator page to find your nearest salon and book a session.
