Blinc's Fountain of Youthful Color® Eye Shadow Primer allows you to have crease-free shadow all day while providing your skin with anti-aging benefits at the same time. This primer for eyeshadow offers full coverage by concealing and filling existing fine lines, eliminating redness, and providing a smooth lid. Then, any powder shadow can be applied for color that won't crease, fade, smudge or run, even if you sweat or wear it in harsh weather conditions! At the end of the day, Blinc's primer for eyeshadow is easily removed, only when you are ready, with any gentle makeup remover. It's better than waterproof!
