Liquid Glass Primer

What it is: A nontoxic nail primer that helps smooth the surface of your nails, filling ridges and increasing color adhesion, too.

What it does: This primer helps your polish last for up to 10 days without chipping. It's formulated with rosehip, which promotes nail growth, coconut oil, which nourishes dry, brittle nails and green tea, which helps makes your nails stronger.

How to use: Begin by cleansing your nails with soap and water, then dry thoroughly. Apply a generous amount of primer to your nails. Follow with two coats of lacquer. Seal with a top coat to help prevent chipping. Be sure to shake well before using and let each layer dry before applying the next.
