I'm sure everyone has their favorite type of concealer. As for me, my favorite type of concealer would me mineral concealer. First of all, I don't need heavy coverage under my eyes, it doesn't have any harmful chemicals and it has some ingredients that help shield our skin from UV rays. Unfortunately, it also has a big downside: you have to apply it in very thin layers, or else it will cake. I honestly don't have the patience to do this every morning, so I apply my concealer in a different way. I combine it with my eye cream.
I just tap a little mineral concealer at the back of my hand, and then mix a small amount of eye cream with it. I end up with a sort of liquid-y concealer.
I find that this method works with most kinds of eye creams. This way, applying concealer becomes a breeze and I don't have to worry about caking. I can control the coverage with the amount of concealer I mix with my eye cream. Plus, I find that mineral concealer stays on me the whole day!
