Blue and red light often get discussed as separate options, yet they sit at opposite ends of the visible spectrum and do very different jobs. Using them together is where things get interesting. Here is how blue light works in skincare, and three benefits of pairing it with red.
How blue light works
Blue light, around 415 nm, is absorbed near the skin's surface. It is commonly used to help keep blemish-prone skin looking clearer and calmer. Red light, around 633 nm, goes a little deeper and is widely used to support a smoother, more radiant look.
1. Clearer-looking skin that still looks healthy
Blemish-focused routines can leave skin feeling tight or dull. Adding red light may help support a fresher, more comfortable complexion alongside the clarifying role of blue, so you are not trading glow for clarity.
2. Support for tone and texture at the same time
Because the two wavelengths work at different depths, a combined session can address surface concerns and overall skin appearance in one go. Over time, that may support a more even-looking tone and smoother-feeling texture, though results vary.
3. A simpler routine
Instead of switching between devices, one multi-wavelength product lets you blend colours in a single sitting. That is a real advantage for consistency, which matters most with light therapy. The Luyors Equinox™ Pro offers 415, 590, 633 and 830 nm across 6 modes, with 10-minute sessions, so you can run blue, red or a combination depending on the day.
Using them well
- Start with clean skin: remove makeup and sunscreen first.
- Be regular: several sessions a week for a few weeks before judging results.
- Keep your basics: moisturiser and daily sunscreen remain essential.
- Listen to your skin: if it feels irritated, reduce frequency.
LED light is a gentle, supportive step rather than a cure for any skin condition. If you have a skin concern, are pregnant, or use photosensitising products or medication, speak with a professional before beginning.
