What it does: Lock-It Color Correcting Eyeshadow Primer is the first eye primer to feature five shades that target discoloration and smooth the appearance of imperfections according to your skin tone. Unlike one-shade-fits-all primers, Kat's formula color corrects your specific skin tone to neutralize lids so that you can show off super-saturated, true color payoff. In an easy-to-use twist stick, this primer features 16-hour wear and Multi-Faceted Color Correcting Pigments for a smooth, even canvas that keeps eye looks in place while keeping them vibrant. With this eye primer, eyeshadow applies pure and true, color payoff is intensified, and eye looks stay fade-proof and crease-free for lasting wear.
