Make Up For Ever raises the waterproof bar with their new Aqua Liner. Using a super-smooth, buildable formula (the lighter the touch, the more sheer the look) and a pointed sponge applicator, brushing on a seriously precise liquid line is a snap. Really. And here's where things get extra juicy: The liner's formula includes polymers that create a flexible, waterproof film and, part of what makes the Aqua Liner's hues so bold and lasting, is an infusion of essential amino acids from apple juice (yep!). The brand put the Aqua Liner to the test at Mercedes-Benz Fashion Week Swim in Miami, and the liner didn't budge—even under hot lights, heat, or humidity (summer, do your worst!). And if you're not afraid to take some color risks, they come in a slew of bright hues like turquoise, green, purple, fuchsia, and red; and metallics that come in gold, white, and a multi-color black. But everyday colors are covered, too, with shades of navy blue, burgundy, and matte brown, and black.
