Green Light Fusion Sheet Mask (Canada and USA only)

Targets all three steps of the melanogenesis pathway, not just one. Most brightening products address a single step in pigment biology — this mask is formulated around the full sequence: CoQ10 and antioxidants neutralize the upstream oxidative triggers, alpha-arbutin inhibits the enzyme that starts pigment production, and niacinamide slows pigment transfer to the surface.

Pairs with 525nm green light from the ETERNO. Melanin's job is to absorb light — 525nm green sits in the wavelength range studied for its interaction with melanin in the skin. The mask addresses how your skin produces and moves pigment; the light interacts with the pigment that's already there. Both at once, on the same biological process.

Science-backed ingredient stack for uneven skin tone. Niacinamide, alpha-arbutin, CoQ10, green tea, sea buckthorn, purslane, and rosemary — each targeting a different point in the pigmentation cycle through different biological pathways, all formulated to work synergistically with green light.
