The Smudge Proof Eyeshadow Base forms an invisible base for your eye make-up and makes the colours look as brilliant all day long as if you had just applied them - this is ensured by polymers and the Mineral Powder Blend. "Deep Sea" extract, known for its anti-inflammatory properties, and extract from rice bran, a powerful antioxidant that nourishes, smooths and protects the skin, enhance the formula. NARS Eye Shadow Primer absorbs quickly and leaves a matte finish; eye makeup is now effortless to apply, won't settle into fine lines, and inspires with hours of hold. Application: Apply a small amount to the eyelid and blend with the fingertip from the base of the lashes to the brows. Ideal in combination with - Instant Line & Pore Perfector - Dual-Intensity Eyeshadow - Larger Than Life Long-Wear Eyeliner.
