8. Throwing away your mascara too soon.
Why it’s wrong: We’ve all heard about the horrible things that can grow in your tube of mascara after keeping it around longer than four months, but that doesn’t mean you should toss it when your formula starts getting too thick, says StyleSeat makeup artist Brian Dean. If it’s before the four month mark, your mascara is probably becoming hard from pumping the tube every day.
Quick Fix: If you find your mascara getting a little too clumpy for your liking, Dean suggests putting two or three drops of saline solution in the tube and stirring with your wand. The added moisture refreshes the formula, which means you’ll get a lot more usage out of it and your lashes will be much smoother and a lot less clumpy.
