Stay-Put System 2 is a formula engineered with a special two-layer protection. One layer penetrates deeper into the skin, and the other layer bonds closer to the skin’s surface. Which means, even if the top layer is wiped off, the underlying layer of protection is still effective. System 2 works well even when applied to thin areas of skin that is then exposed to high heat or humidity – making UV rays a non-issue – even in the most extreme conditions.
