Hoping Red Light Therapy will give you a bronzed glow without frying in the sun? Short answer: no, RLT won’t tan your skin because it doesn’t produce UV, but it can make your skin look healthier and brighter. Before you ditch your SPF or book a tanning bed, let’s break down what this treatment actually does, and why so many people confuse its glow with a tan.
The confusion usually begins when people see glossy red light tanning before and after photos online. The “after” shot often looks warmer or more radiant, so it’s easy to assume the skin has tanned. What’s really happening is an increase in circulation and collagen activity, not melanin production. Red Light Therapy works with your cells, while tanning works against them. Different light, different purpose, completely different outcome.
A tan only develops when the skin absorbs UV rays, which push your melanin into action. RLT operates nowhere near the UV range, so there’s nothing in the treatment that can signal your skin to darken. Some salons market “red light therapy tanning,” but what they really offer is tanning and red light therapy together, two separate treatments placed side by side. One darkens the skin; the other repairs it. There is no overlap.
When UVA or UVB rays hit the skin, they cause DNA damage at the cellular level. Your skin reacts by producing melanin, hoping to shield deeper layers from further harm. That bronzed colour many people chase is literally the skin’s attempt to protect itself. It’s clever biology, but not exactly a beauty treatment.
You might think of a tan as a holiday souvenir, but dermatologists view it more like a warning label. A tan means your cells have been stressed enough to trigger a defence response. Repeating that cycle leads to wrinkles, pigmentation issues, and increased cancer risk. There’s no such thing as a “safe” UV tan, only a controlled burn.
Red Light Therapy dives into a completely different part of the spectrum. These wavelengths reach the mitochondria, your skin’s tiny power stations and boost ATP, the fuel cells use for repair. That’s why your skin looks more alive afterward. The glow you see in red light tanning before and after images is circulation and healing, not tanning pigment.
UV triggers inflammation and oxidative stress. RLT calms inflammation and increases cellular repair. Where UV breaks collagen, RLT helps build it. This is why people talk about red light tanning bed benefits even though there’s no tanning involved. They’re really describing the improvements in tone, texture, and overall skin quality.
A tanning bed is designed with one job: to force your skin to darken. A red light panel has an entirely different mission: to improve how your skin behaves. One increases melanin; the other increases ATP. Many salons pair the two services, but that doesn’t change their roles. If UV tanning pushes your skin into defence mode, RLT pulls it back toward balance and recovery.
A typical RLT session feels like stepping into a gentle, comforting warmth, not like standing in direct sun. Your skin won’t burn, tighten, or darken. What you will notice afterward is a soft glow, especially if you’re comparing your own red light therapy tanning progress photos. That glow is simply healthier, better-functioning skin. You’re not getting a tan; you’re getting vitality.
Yes. Because it speeds up cellular turnover and repairs UV-related inflammation, RLT can help your skin return to its natural tone more quickly. It doesn’t bleach the skin, it just helps it heal.
When salons combine tanning and red light therapy together, the treatments are still separate. UV beds create colour; red light improves skin health. They may sit in the same room, but they do completely different jobs.
RLT can strengthen the skin barrier and reduce inflammation, but it cannot prevent sunburn or make tanning safer. You’ll still need sunscreen, shade, and sensible sun habits.
