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