When you apply your mascara, steer clear of your bottom lashes. "Avoid mascara on the lower lash line because it can easily smudge, bringing more attention to the under eye circles and bags, which tend to get worse as we age," Bass says. Instead, focus your lash-plumping efforts on your upper lash line.

Start with the wand close to the root of the lash and gently wiggle back and forth to get as much product on the base of the lash as possible. Then slightly angle your mascara up and wiggle back and forth up the length of your lashes. Apply two to three layers of mascara. To avoid clumps, Bass recommends running a clean mascara wand through your lashes between coats while the product is still wet.
