Plumping Top Coat is great on top of nail strips. Like the Nail Strengthener, make sure your nails have totally cured, or the bottom layer will never harden. I like to apply Plumping Top Coat OR Nail Strengthener OVER my manicure the day after I do a manicure, assuring total hardening of my nail polish strips.
Many people say you only have to wait about 45 minutes. If that works for you, that is great. But if you feel your nail polish and top coat aren't hardening, then wait longer.
Matte is not my personal favorite look, as I am a gloss girl. But, I can attest that when I put this on, just one coat, a HUGE transformation occurred. It blew my mind. Really, really pretty and works like a dream.
