Red vs. Blue Light: Which One Does Your Skin Actually Need?

From acne to fine lines, different wavelengths target different issues. Learn how red and blue light therapy work — and when to use each.

If you’ve ever wondered whether to reach for red or blue light, you’re not alone. These colors do more than set the mood — they set the function. Red light renews from deep within, rebuilding collagen and calming irritation. Blue light clears the surface, targeting the bacteria that trigger breakouts. Understanding the difference is the first step to using light therapy like a pro — and choosing the mode your skin actually needs.

Red Light (660 nm):

Penetrates deeper layers of the skin to stimulate collagen, improve firmness, and reduce fine lines. Ideal for dullness, dryness, and visible aging.

Blue Light (460 nm):

Targets acne-causing bacteria, minimizes inflammation, and soothes redness. Perfect for oily or breakout-prone skin.
