The Science Behind Red Light Therapy — and How I’m Using Mine for Glowy, Slower-Aging Skin

Giel having a Celluma Red Light Therapy Session

Red light therapy isn’t new, but it’s having a real moment — and for good reason. It’s one of those rituals that feels both relaxing and effective, like a facial and meditation rolled into one.

I started using my Celluma LED red light device a few years ago, mostly out of curiosity. Now it’s become part of my weekly routine — and honestly, I notice a real difference. My skin looks calmer, more even, and just… happier.

So let’s talk about what it actually does, how I use it, and what the science says.

What red light therapy actually is

Red light therapy (also known as low-level light therapy or photobiomodulation) uses specific wavelengths of light — usually between 630–850 nm — to reach below the skin’s surface. These wavelengths stimulate mitochondria, the energy centers in your cells, which can help repair and rejuvenate tissue.

In simple terms: it helps your skin work better from the inside out.

The science in simple terms

Several studies have shown that red light therapy can:

  • Boost collagen production (the protein that keeps skin firm and smooth)

  • Reduce inflammation and redness

  • Support wound healing and tissue repair

  • Improve overall skin tone and elasticity

One review published in the Journal of Clinical and Aesthetic Dermatology found that consistent red light use improved skin texture and reduced fine lines by stimulating fibroblast activity — which is basically how new collagen is made.

So while it sounds high-tech, it’s actually grounded in real, peer-reviewed science.

How I use my Celluma device

I like to think of it as a “me-time” ritual rather than a treatment.

Here’s my go-to setup:

  • Cleanse my face (no makeup or SPF)

  • Apply a light serum — nothing occlusive

  • Use my Celluma red light panel for 20-30 minutes, about 3-4 times a week

  • Follow with moisturizer and a few drops of face oil

Sometimes I’ll listen to music or meditate while it’s on — it’s actually one of the calmest parts of my week.

Why it’s worth it

Red light therapy isn’t an overnight fix — it’s one of those slow-and-steady rituals that really add up.
Think of it like exercise for your skin cells: the more consistently you do it, the more visible the results.

After a few weeks, I noticed:

  • Less redness

  • Softer texture

  • More balanced tone

And even on days I skip it, my skin feels more resilient.

A few tips if you want to try it

  • Be consistent — results come from regular use, not intensity.

  • Always start with clean skin.

  • Skip acids or retinol right before use (it can make skin more sensitive).

  • Don’t stare into the light — close your eyes or wear goggles if you prefer.

  • Make it part of your nighttime wind-down routine for extra relaxation.

This isn’t about chasing perfection — it’s about supporting your skin’s natural rhythm and giving it tools to heal itself.

Whether you’re using a Celluma or another device, red light therapy can be one of the simplest ways to help your skin glow, calm down inflammation, and age a little slower — in the most natural way possible.
