The Best Under-$25 Sephora Makeup When You Want to Look Like You're Not Wearing Any

IT Cosmetics Tightline ($24) is three-in-one primer, eyeliner, and mascara. It goes on like mascara but begins by adding a little color at the lash line (like a liner) while the biotin, proteins, and hydrolyzed collagen nourish and separate your lashes root to tip. This is more subtle than a regular mascara but, since it comes in black, also does the same thing a primer would do without a noticeable white residue.
