Mascara - Products Knowledge

generally comes in three formulas:

Thickening mascara coast each individual lash from root to tip with particles that add black to the lashes and help them to look thick and full.

Lengthening mascara contains plastic polymers that cling just to the tips of the lashes, making them appear longer.

Defining mascara coats the individual lashes, keeping them separated and defined. Defining mascara usually appears the most natural.

Most mascara is also available in a wateproof formula. However, unless you're susceptible to allergies that make your eyes water, you might not want a waterproof mascara because it's harder to remove and can damage delicate lashes. Also, women with sensitive eyes might want to stay away from waterproof because it is the most irritating of all formulas.
Most women don't relize that the mascara wand is just as important to the finished result of your lashes as the mascara formula.
