Why You Might Want to Think Twice About Using Waterproof Mascara

Plus, other sneaky culprits that could be hurting your delicate eye area

Dark circles under your eyes that even concealer can't hide? The problem could be coming from your sleep habits or from rubbing your eyes—but there are even sneakier culprits you might not know about. Dermatologist Ellen Marmur, M.D., goes all super-sleuth to uncover them.

1. Waterproof Mascara
They often require rubbing to remove, which intensifies rings. Switch to a formula that's not marked long wear.

2. Eyelash Extensions
These faux lashes are applied with glue that many people are allergic to, resulting in irritation and circles around the eye area.

3. Swimming Goggles
They add suction and pressure to the under-eye area. Reach for a pair of open-water goggles—they rest on the outside of the orbital rim.
