Lancome's favourite Définicils mascara provides lash separation. The exclusive eye makeup formula shapes and defines to create longer looking, beautiful lashes from base to tip without clumping. The grooved bristles on the patented brush evenly distribute mascara along the entire lash from root to tip. Separates the look of eye lashes for a natural-looking, even finish every time. How to apply Définicils: Apply mascara from the base of the lashes to the tips using zigzag movements. When you apply mascara this way, you will be able to direct and perfectly distribute the texture of mascara onto the lashes. Apply mascara from the base of lashes to the tips using zigzag movements. Pro tip: Never pump the wand as this will introduce air into the barrel of the mascara which can dry out the product.
