If you’ve been researching red light panels, laser lipo pads or sculpting domes, you’ve probably come across terms like 532nm, 635nm, or 850nm — and let me guess: you’ve either nodded along or gone totally cross-eyed wondering what it all means. 😵💫
So let's clear it up once and for all — because 2025 is the year of low-level laser therapy (LLLT), and knowing your wavelengths could change the way you treat clients (or yourself!).
👇 First — What does “nm” mean?
“nm” = nanometres, the unit of light wavelength.
Different wavelengths = different effects on the body.
Think of them like layers:
Some lights work on the surface (bye bye fluid retention),
Others go deep into fat cells (hello inch loss),
And some go right down to muscle level (hello recovery and healing).
🔬 The 3 Powerhouse Wavelengths in Body Contouring
🟢 532nm – Green Light
✨ Lymphatic Booster | Surface-Level Targeting
This light targets the top layers of skin and tissue and is known for supporting:
Lymphatic drainage
Water retention
Fluid bloat
Stagnant results
🔋 Bonus? Your eyes respond 8x more to green than red light — so it feels more intense, even if the energy is lighter.
👉 Use this for clients who feel “stuck,” puffy, or not shifting as expected. Green light clears the way.
🔴 635nm–650nm – Red Light
🔥 Fat Cell Activation | Collagen Production | Skin Tightening
This is the star of fat loss wavelengths — and it’s found in:
=ContourIQ™ fat loss pads
=Laser lipo belts
=Most pro-grade sculpting machines
What it does:
=Penetrates deeper to stimulate fat cells (adipocytes)
=Triggers fat cells to release fatty acids
=Boosts ATP (energy production)
=Helps build collagen + improve skin elasticity
💡 It’s your go-to for targeted inch loss, and works beautifully with cavitation or RF skin tightening.
⚫ 850nm – Near Infrared Light
💪 Deep Tissue Support | Recovery | Inflammation Control
This one goes way down deep.
Found mostly in red light therapy panels, especially full-body ones, it’s all about:
=Reducing inflammation
=Improving circulation
=Muscle repair
=Post-EMS recovery
=Pain management
👀 You won’t see this light (it’s invisible to the naked eye), but it works hard behind the scenes for recovery and rejuvenation.
🧠 “So Which One Should I Use?”
Here’s the truth: They all do different things — so if you’re in the body contouring world, you’ll probably want a mix of devices and wavelengths. Here's how we use them at Bodi Slim:

🌟 Perfect for clients who want fast, full-area results AND support their lymphatic flow.
✅ Wrap Up: What You Really Need to Know
Light Wavelength (nm) Main Use Power Results
🟢 Green 532nm Lymphatic & Bloat Surface Debloats, clears stagnation
🔴 Red 635–650nm Fat loss & Collagen Medium Inch loss, skin firming
⚫ Infrared 850nm Recovery & Healing Deep Pain relief, cell repair
If you’re a salon owner, student, or body sculpting queen wanting to level up your treatment results, understanding light therapy isn’t just smart — it’s essential.
