The Benefits of Red Light Therapy
Red Light Therapy: What It Is, the Different LED Colors, and How They Benefit Your Skin
If you’ve been hearing all the buzz about red light therapy lately, you’re not alone. This science-backed skin treatment is making waves for its ability to improve skin health, boost collagen, and even help with inflammation—all without downtime or harsh side effects.
But not all LED light colors are the same. Each wavelength (color) penetrates the skin at different depths and has unique benefits. Let’s break down what each one does so you know exactly what’s going on when you flip the switch on your device.
What Is Red Light Therapy?
Red light therapy uses specific wavelengths of light (measured in nanometers) to stimulate your skin’s natural healing processes. Unlike UV light, which can damage skin, red and near-infrared light work at a cellular level to:
Boost collagen and elastin production
Reduce inflammation and redness
Speed up repair and recovery
Improve skin texture and tone
The process works through photobiomodulation—light energy absorbed by your cells’ mitochondria, the "power plants" inside your cells. This energy gives your skin cells the boost they need to repair and rejuvenate themselves.
The Different LED Colors & What They Do
While “red light therapy” often refers to the visible red spectrum, high-quality devices also include other colors to target different skin concerns. Here’s a quick guide:
🔴 Red Light (around 630–660 nm)
Best for: Boosting collagen, reducing fine lines, improving skin texture
How it works: Penetrates the top layers of skin to energize cells and stimulate collagen and elastin
Results: Firmer, smoother skin over time
🔴 Near-Infrared Light (around 810–850 nm)
Best for: Deep tissue repair, inflammation, pain relief
How it works: Penetrates deeper into the skin and muscles, encouraging healing and reducing swelling
Results: Improved skin health plus relief from aches, joint pain, and inflammation
🔵 Blue Light (around 415–450 nm)
Best for: Acne and breakouts
How it works: Targets and destroys acne-causing bacteria (P. acnes)
Results: Clearer skin and reduced active breakouts
🟢 Green Light (around 520–550 nm)
Best for: Hyperpigmentation, sun spots, skin redness
How it works: Helps regulate melanin production and calms irritation
Results: More even skin tone and reduced redness
How Often Should You Use Red Light Therapy?
For at-home devices like those from Bon Charge, here’s the general guideline for best results:
Frequency: 3–5 times per week
Session length: 10–20 minutes per area
Distance from device: Typically 6–12 inches away (follow your device manual)
Duration for results: Many users notice improvements in skin texture, tone, and fine lines within 4–8 weeks of consistent use
💡 Pro tip: Consistency is key. Think of red light therapy like going to the gym for your skin—results build over time, and stopping treatments can gradually reverse your progress.

Bottom line:
Red light therapy isn’t just a beauty trend—it’s a science-supported way to boost your skin’s natural renewal process, slow the signs of aging, and support overall skin health. With the right device (like Bon Charge) and a consistent routine of 3–5 sessions a week for 10–20 minutes each, you can bring spa-quality treatments into your own home and enjoy glowing results year-round
