Does Red Light Therapy Make You Tan? What Actually Happens to Skin
It is an easy assumption to make. You stand in front of a glowing panel, the light is warm, and it looks a little like the tanning beds people have used for decades. So it is natural to wonder whether red light therapy will change your skin color the way a tanning session does.
It will not, and the reason it will not is the same reason red light therapy is considered a gentle, supportive tool rather than a skin risk. The whole answer comes down to one thing: the type of light involved. Interestingly, that same difference is why red light is studied for helping the skin cope with the sun rather than damage it.
Quick Answer
No, red light therapy does not make you tan. Tanning is caused by ultraviolet (UV) light, which triggers melanin production as a protective response to skin damage. Red and near-infrared light contain no UV, so they cannot stimulate a tan. In fact, research suggests red light may help support the skin's resilience against UV damage and may support faster recovery from a sunburn, though it is never a substitute for sun protection.
What actually causes a tan
A tan is not a sign of health. It is your skin defending itself. When ultraviolet light hits the skin, it damages skin cells, and in response those cells produce more melanin, the brown pigment that darkens your skin to absorb and block further UV. The tan is the visible result of that protective scramble.
This matters because it tells you exactly what is required to produce a tan: ultraviolet exposure. No UV, no melanin trigger, no tan. Everything else about the light source, how warm it feels, how bright it looks, what color it appears, is beside the point. The only question that determines whether something can tan you is whether it emits UV.
Red light vs UV light
Ultraviolet and red light sit on opposite sides of the visible spectrum, and the gap between them is the whole story. UV is shorter in wavelength and higher in energy than visible light. It is energetic enough to damage skin cells and DNA, which is why it drives both tanning and, with enough exposure, skin aging and cancer risk.
Red and near-infrared light are longer in wavelength and lower in energy, running from roughly 630 to 1060 nanometers. They are non-ionizing, meaning they cannot damage DNA, and they contain no ultraviolet component at all. A quality red light panel is engineered to emit only its target red and near-infrared wavelengths, not the UV that tanning requires. Our wavelengths guide shows exactly where these sit on the spectrum.
UV light damages skin, and the tan is the repair response. Red light supports skin cells without damaging them, so there is no repair response to trigger and no pigment change to produce.
Why people confuse the two
The mix-up is understandable, and it comes from a few directions. Red light panels visually resemble tanning beds, both are bright and warm, and some tanning salons have begun offering red light therapy as an add-on service, which blurs the line further in people's minds.
There is also the warmth. Near-infrared light is felt as gentle heat, and we associate warmth on the skin with sun exposure, which we associate with tanning. But warmth is just heat, not UV. A warm panel is no more capable of tanning you than a warm bath. If a device darkens your skin, it is emitting UV, and a properly built red light therapy panel does not.
What red light does to skin instead
If red light is not changing your pigment, what is it doing? Rather than triggering a damage response, red and near-infrared light are absorbed by the mitochondria in your skin cells, where research suggests they may support cellular energy production. Many users turn to red light therapy to support skin tone, texture, and recovery rather than color.
That is why red light shows up in conversations about wrinkles, rosacea, and general skincare routines, and not in conversations about getting color. The goal is supporting the skin you have, not darkening it.
Red light and sunburn
Here is the part that surprises people. The same qualities that make red light incapable of tanning you are why it is studied for helping skin cope with the sun. Because red and near-infrared light support the skin's own repair machinery rather than damaging it, research suggests red light exposure may help support the skin's resilience to UV and may support faster recovery when you have already been burned.
The proposed mechanism is the familiar one. A sunburn is inflammation and cellular damage from UV, and healing it takes energy, circulation, and controlled inflammation, the same three things red light is studied for supporting. Some users report that red light sessions help calm the redness and discomfort of a burn and shorten how long it lingers. This should be understood as supportive, not proven, and gentle care of already-inflamed skin still applies.
Red light therapy is not sun protection and is not a substitute for sunscreen, shade, or covering up. It does not block UV or prevent sun damage. It is explored as a supportive tool for skin resilience and recovery, not a reason to spend more time unprotected in the sun. Severe or blistering burns should be seen by a healthcare provider.

Frequently Asked Questions
Does red light therapy give you a tan?
No. Tanning requires ultraviolet light, and red light therapy contains no UV. Without UV, there is nothing to trigger the melanin production that darkens skin, so red light therapy cannot produce a tan.
Can red light therapy help with sunburn?
Research suggests red and near-infrared light may support the skin's resilience to UV and may support faster recovery from a sunburn by aiding circulation, cellular energy, and the calming of inflammation. Some users report reduced redness and discomfort. It is supportive, not a cure, and it is not sun protection.
Is red light therapy the same as a tanning bed?
No. Tanning beds emit ultraviolet light specifically to darken skin. Red light panels emit red and near-infrared light with no UV, and are used to support skin and cellular health rather than to change skin color.
Why does red light therapy feel warm if it is not like the sun?
Near-infrared light is felt as gentle heat, which we tend to associate with sun exposure. But warmth is just heat, not ultraviolet light. The warmth has no ability to tan or damage skin on its own.
Can red light therapy replace sunscreen?
No. Red light therapy does not block UV and is not sun protection. It may support skin resilience and recovery, but you still need sunscreen, shade, or clothing to protect against sun damage.
Do I need eye protection even though there is no UV?
Near-infrared light is bright and partly invisible, so goggles are recommended when the panel is aimed at your face. This is about comfort and eye safety around intense light, not about UV. Goggles are included with our panels.
