So many have asked for me for mascara recommendations, and while they aren't one size fits all, everyone can agree that flaking is a dealbreaker.
This tube (primer on one end, and black mascara on the other) is a weekday staple, as there's nary a flake to be seen by the time I've got the, kids in bed and starting to wind down.
The primer (not critical, but recommended) conditions the lashes, and preps them to build length and thickness without inviting clumps. While buildable, I wouldn't go more than 3 coats total, and the effect is lovely. Long, gently curled lashes that both look natural and hold up throughout the day.
