Mermaids are portrayed as beautiful, siren-like creatures with gorgeous, long locks; glowing skin and perfect makeup that never runs. But in real life, we know Ariel's fire-engine red hair wouldn't stand a chance against the sun and water.

What's a mermaid to do? We asked the closest thing to it, members of the Aqualillies, a professional synchronized swimming troupe, who can spend a whole day in the water, and still look gorgeous. Here, their best summer hair, makeup and skin care secrets against which chlorine, sun and surf don't stand a chance.
