I was so excited when I found out OPI makes a matte top coat! I love the look of matte nails and the top coat allows you to give any of the polishes you already own a matte finish! It works very well and looks amazing for the first couple of days. However, it does begin to wear off after a few days and your polish just begins to look a little shiny.
I've been told to avoid using hand sanitizer while you have it on as it wears the matte finish off quicker.
