EVY’s patented formula has several unique features that give you superior protection. It forms a protective barrier that enhances your skin’s natural defenses. The mousse spreads throughout the top layer of skin, instead of staying on the surface which many creams do, and it doesn’t rub off, whether you swim, sweat, or dry yourself with a towel. This means you get very long-lasting protection against both UVA and UVB rays. Our products also protect your skin from heat, wind and water stress as well as skin irritants such as chlorinated or salty water, algae, or soap.
