After seeing some tips on Pinterest about making your own matte nail polish with cornstarch, there was no link on how to do it, so I had to go ahead and experiment on my own.
I started with some clear nail polish and some cornstarch.
Add cornstarch, a little at a time, and shake it up to mix well until the polish is nice and white.
I quickly painted a couple nails with this purple polish that is always very glossy.
This is how the polish looks when it is dry.
After topping it with a coat of the cornstarch polish, this is how it looked. Definitely toned down! I think the more corn starch you add to the polish, the more matte it will appear.
