I made an experiment on my Etude House Matte Nail polish in muddy grey.
(I don't know the real name of this shade so I just wanna call it muddy grey, okay? LOL. :p
You'll see the label below.)
I tried applying top coat / clear polish over the matte one and you'll see what it deed to my nails.
Here's how it looks like with base coat and 2 coats of matte polish.
Now I applied my favorite nail tip design using Bobbie's Electrified.
And applied 1 coat of clear polish / top coat.
After application, nothing's changed except for the color.
It looks a little bit yellow than it's original shade.
But, after 5 hours or less I noticed something on my thumb and pinky finger.
It looked damaged. Cracked to be exact.
Here's a closer look on my thumb.
I didn't do anything that might cause this. Maybe it's a chemical reaction.
I tried using my other Etude House matte polish with a clear top coat but it's okay.
Maybe this grey-ish matte polish has something that other polishes doesn't have eh?
Now I'm thinking of combining the two (top coat and matte polish),
I might just end up creating crackle polish. LOL.
Here are the things I've used.
