The super potent mascara, based on the science of Estée Lauder, instantly gives volume and length while nourishing the lashes. The formula with 100% natural maracuja, argan, and castor oils protects and nourishes the lashes, making them visibly stronger and thicker. The filling ingredients glide lightly on the lashes, and the texture is enriched with microscopic spheres of silica for an instant effect. Offering 12 hours of strength, length, volume, and curl, this is the best Estée Lauder mascara that does not smudge or flake. Self-assessment test conducted on 106 women after one week of use.
