Frequently Asked Questions
-
Is this product different from the Infinity Waterproof Liquid Liner™ you carried previously?
Based on the feedback we've received from our customers, we wanted to make some changes to our liquid eyeliner for easier application. The Infinity Waterproof Liquid Eyeliner Pen™ comes with a brush tip for a more stable hold, easier application, and feather-free wear.
Which shade works best for my eye color?
While Lauren and Ella can be worn with all eye colors, we recommend Ella (Brown) for those with lighter eyes who want dramatic definition without looking too harsh or overpowering. Ella will give a soft dimension to your eyes while still making them appear rich and intense. Lauren (Black) is a timeless staple that will look pair well with any eye look.
What if I make a mistake when attempting to create a wing liner?
While our Liquid Eyeliner Pen features a bold-pigment formula that dries quickly and won't smudge, it can be easily cleaned up. We have two tips for these instances.
Take a Q-Tip and dampen it with warm water or your favorite makeup remover. Simply glide the dampened end across any places you want to straighten your wing.
Using the Precision Angled Eyeliner Brush™, apply a small amount of Buildable Blur™ Concealer, and follow a straight line at the bottom of your wing.
