"To create the illusion of thicker lashes, apply eyeliner to the upper inner rim of the eye. Use a pointed eyeliner brush with a cake eyeliner to apply liner as close to the lash line as possible." -- Chad Hayduk, makeup artist and Co-Founder of Three Custom Color Specialists.

"Finding the right wand is imperative for lengthening lashes -- look for a smaller wand with lots of teeth bound close together. This will reach the lash roots and extend the hair as much as possible to lengthen and separate lashes.

One to try: Lancome Definicils Mascara, $24.

A bigger fluffy wand is best for creating voluptuous lashes. The bendable, pliable teeth hug the lash curves and allow many coats to be applied on top of each other." -- Bettelli

One to try: Benefit BADgal Lash, $19.

"I always, always use at least two different mascaras when I'm doing makeup. I like to use one that really gets the mascara into the roots of the lashes (like Maybelline Lash Discovery, $6.59), and another to lengthen and extend the lashes (like Lancome Virtuose Mascara, $23.50). Having a good amount of mascara at the roots of the lashes makes the lashes look fuller and thicker, without having to rely on eyeliner." -- Makeup Artist Fiona Stiles

"Make top lashes look longer by pushing outer lashes towards the temples, the middle ones up towards the brows, and the inner lashes to the nose. This sunray effect drastically makes lashes look longer. Apply the same technique to lower lashes with the center lashes pointed straight down towards the jaw." -- Bettelli

"Always use the freshest, newest mascara. You�ll never get the results you want with a dried out formula." -- Hayduk

We recommend replacing your mascara every three months.
