Short answer: red light therapy uses gentle red and near-infrared LED light to support the look of calm, even, radiant skin. It's a relaxing, non-invasive at-home step, lovely on its own or as a finish after a salmon DNA (PDRN) serum. Here's the plain-English guide. Browse red light therapy devices.
What is red light therapy?
Red light therapy (also called LED light therapy) uses specific wavelengths of visible red light, typically around 630–660nm, and often near-infrared light around 830nm. At home you'll find it as masks, panels and stands. It's a comfortable, warming-but-not-hot experience: you wear the mask or sit in front of the light for a set time. As a cosmetic step, it's valued for supporting the appearance of calm, even, radiant-looking skin, and for being a genuinely relaxing wind-down.
What people use red light therapy for (cosmetically)
Red light is a gentle, cumulative step rather than an overnight fix. Here's how people tend to value it, all in terms of how skin looks and feels:
- The look of radiance: a fresh, healthy-looking glow with consistent use.
- The look of calm, even skin: a comforting step that supports the appearance of a settled, even-looking complexion.
- A relaxing ritual: 10–20 minutes of warm light is a lovely way to unwind, and an easy habit to keep.
- Better-feeling routine: a gentle finishing step that pairs with the serums and moisturisers you already use.
An honest note: red light therapy is a cosmetic step that supports how your skin looks and feels. It isn't a medical treatment and isn't intended to diagnose, treat or cure any condition. If you have a specific skin concern, check in with a GP or dermatologist.
Red light vs near-infrared: what's the difference?
Visible red light (around 630–660nm) works at the surface and is the classic choice for the look of radiant, even skin. Near-infrared (around 830nm) is a longer, invisible wavelength that reaches a little deeper for a more thorough-feeling session. Many modern devices, like our Dual Near-Infrared & Red Light LED Face Mask, offer both.
How to use red light therapy at home
- Start with clean skin. Cleanse and pat dry; light works best on bare skin.
- Apply a gentle serum (optional). A fragrance-free salmon DNA (PDRN) serum is a lovely base.
- Run your session. Usually 10–20 minutes, following the manufacturer's instructions. Wear any included eye protection.
- Finish with moisturiser (and SPF in the morning).
Consistency matters more than intensity: a few sessions a week, kept up over time, is the way to get the most from it. For a step-by-step beginner walk-through, see our LED red light therapy at home guide.
How often should you use it?
A typical rhythm is three to five sessions a week of 10–20 minutes. More isn't necessarily better, so follow your device's guidance and let consistency do the work over several weeks.
Red light + salmon DNA: a lovely pairing
Many people use red light as the final, relaxing step after a hydrating routine. Apply a gentle PDRN serum, then enjoy your light session, then seal with moisturiser. It's a calm, low-effort way to round out your skincare.
