The science of GlowUp™ LED

Light, explored
Skin, explained

How GlowUp™ LED masks use four wavelengths of light, across six modes, in a 10 minute hands-free ritual.

Four wavelengths

Every color of light
has its own job

Light is measured in nanometers (nm). Shorter blue wavelengths are absorbed near the surface of the skin, while longer red and near-infrared wavelengths travel deeper. GlowUp™ masks combine four of them across six modes.

Red

635 nm

For skin that looks smoother and more radiant.

Red + NIR

635 nm + 850 nm

Red paired with near-infrared, for the look of fine lines.

Infrared

850 nm

Near-infrared light, invisible to the eye and the longest wavelength in the mask.

Blue + Red + NIR

465 + 635 + 850 nm

All three together, for blemish-prone skin and the look of fine lines.

Blue

465 nm

For blemish-prone skin.

Amber

605 nm

For a more even-looking skin tone.

Choose one mode per session. Mode descriptions are cosmetic, and individual results vary.
