I've always liked the matte look for some subtle nails, and think that when you add a matte topcoat it makes the polish instantly classier. I've tried a whole heap of matte top coates, including sally hansen and OPI. This one works amazingly, definitely same 'matteness' if not better. It's quite thin so applies smoothly and dries out super fast. And once it's dried it's a got absolutely no shine at all.
Very reliable and handy to have, and it'll 'upgrade' any nail polish in your collection. And you can always reapply a couple days later if your nails start to look shiny again. Decent amount in this bottle too, mine has lasted me 8 months so far and still has at least half left!
This was the first top coat I have ever purchased and I fell in love in first use which means I haven't gone to try any other matte top coat yet! As soon as I put it on, I can tell straight away that it works because you start seeing the matte look even if it hasn't dried. A plus to this is that it also dries really quickly, by the time you finish applying it to your second hand the first hand is dry already!
Tips: use thin layers and layer more on top to get an even more intense matte look
