Where Lasers Fall on the Spectrum

If lasers are all about precision, then knowing where each one falls on the electromagnetic spectrum is your roadmap to getting the exact right treatment for your skin concern.

Every laser has a wavelength — measured in nanometers (nm) — that determines how deep it goes into the skin and what it targets. Some are surface-level snipers, others dive deep to hit collagen, pigment, or vascular structures.

There’s a full-spectrum breakdown of the most-used wavelengths and brands you might have heard before on the next page!

Why This Matters

• Safety: Deeper skin tones do better with longer wavelengths like 1064 nm, which bypass melanin.
• Precision: Need pigment removal? Shorter wavelengths target melanin with surgical accuracy.
• Depth: Want collagen stimulation? Longer wavelengths or water-targeting lasers are your go-to.

Whether you’re looking to soften lines, fade pigment, zap vessels, or jumpstart collagen — there’s a laser wavelength for that. The magic happens when the right laser, right settings, and right skin type come together.
