I think this is one of those products that everyone ended up buying and has used in there life. This is one of the first mascara I got as kid. It lengthens yours lashes and doesn't smudge throughout the day.
I absolutely loathe this concealer - odd shade range and packaging with a splotchy and uneven coverage that emphasises dryness and lines. I also think $20 is ridiculously expensive for a maybelline product. I definitely hated this.
A concealer is used for coverage. This is more like a foundation in a mini bottle. I think the estee lauder double wear foundation does more coverage than this concealer. Still for its price range, its the best concealer out there.
It is indeed not bad, however I prefer other maybelline products of these, for instance the highlighter that is sold separately is just so lovely and it gives a beautiful glow. For beginners this is great for starters
