The iconic Diorshow Maximizer 4D lash primer-serum improves mascara performance with a four-in-one formula that lengthens, volumizes, curls and defines, for lashes that appear oversized, immediately and for 24h*. The floral extract infused formula coats lashes and improves lash appearance day after day. Lashes appear visibly longer, nourished, smoother and suppler. Diorshow Maximizer 4D can also be applied on its own at night as a lash conditioner. The oblique brush delivers just the right amount of product to create fuller, curled and fanned lashes for a spectacular wide-eyed look. * Instrumental test on 25 subjects."
