Sunspots, fine lines, or skin that looks just a little less radiant after summer… sound familiar? Sometimes it seems as though your skin needs weeks to recover from all that sunlight. Red light therapy is often mentioned as a gentle way to support that recovery. You can read how exactly it works below.

What exactly is sun damage?
We all know that the sun feels good, but your skin sometimes sees things differently. UV radiation can cause considerable damage, often without you noticing it right away.
Common signs of sun damage include:
- fine lines and wrinkles
- pigmentation spots or dark patches
- redness and irritation
- dull, rough, or leathery skin
- loss of elasticity
- visible blood vessels
- and of course… sunburn
UV radiation damages the DNA in your skin cells, breaks down collagen and elastin, and can even increase the risk of skin cancer in the long term. UVA (which penetrates deeper into the skin) and UVB (which causes superficial burns) play a major role in this.
How does red light therapy work for sun damage?
It may sound contradictory: using light to repair light damage. But red light works completely differently from UV.
Red light (around 630–700 nm) and near-infrared light (up to approximately 850 nm) have longer wavelengths that penetrate deeper into the skin. They activate the mitochondria, the energy factories of your cells, giving your skin literally more energy to repair itself.
What happens then:
- More collagen & elastin: your skin becomes firmer and smoother.
- Less inflammation: redness and irritation decrease.
- Better circulation: more oxygen and nutrients for your skin.
- Faster recovery: damaged cells are replaced more efficiently.
- Support for sunburn: red light may help soothe the inflammatory response following UVB damage.
What is red light used for?
Red Light Therapy is often used for various skin and recovery processes, including:
- Support for sun damage (such as hyperpigmentation, redness, and fine lines)
- Stimulating collagen and elastin for firmer, smoother skin
- Reducing inflammation and soothing irritated skin
- Improving circulation and oxygen supply to the skin
- Accelerating cell repair after damage or irritation
- Support for wound healing and skin regeneration
- Improving the skin barrier and hydration
- Support for redness or sensitivity after sun exposure or other triggers
- General skin rejuvenation and improvement of tone and texture

What does the science say?
Red Light Therapy is being studied more extensively, but not everything has been 100% proven yet. What we do see in various studies is that red light has interesting effects on skin recovery, including when sun damage is present.
- Support for DNA repair & reduced inflammation: A study shows that red light may help clear certain forms of UVB-related DNA damage more quickly and reduce inflammatory responses.
- More collagen & improved skin structure: Research shows that red light stimulates collagen production and improves skin texture. This is important because UV radiation breaks down collagen.
- Faster cell recovery & regeneration: Another study shows that red light activates the mitochondria, giving cells more energy to recover. This speeds up wound healing and reduces inflammation.
How do you use Red Light Therapy lamps?
Want to get started yourself? These guidelines can help:
- Frequency: 2 to 5 times a week works well for most people.
- Duration: 10 to 20 minutes per session.
- Distance: approximately 15 to 30 cm from the skin.
- Consistency: short, regular sessions are better than very long sessions every now and then.
- Listen to your skin: Does your skin feel calmer, less warm, or simply more comfortable? Then you're on the right track.
You don't need to do anything special: no creams, no heat, no complicated steps. Just sit for a moment, relax, and let the light do its work.
Conclusion
Red Light Therapy can certainly support your skin as it recovers from sun damage. It helps calm redness, stimulates collagen production, and gives your skin extra energy to recover. It does not replace medical treatment, but it can be a pleasant, gentle, and effective addition to your routine.
