Barry M’s Matte top coat does exactly what it says on the bottle. It’ll make any polish nice and matte. It costs £2.99 online or from your local stockist.
It’s pretty much perfect because it does what it says it should. Even fake nails will be turned matte with this polish over the top. The chip resistance is good although after a while you can wear it down and it goes a little shiny.
However it’s only £2.99 and really does do the job perfectly.
