Zinc Sunblock is a water free formulation designed for high moisture and complete water immersion environments.  A firm paste that softens once on your warm fingers.  Rub a little between your hands then pat and blend over the face, chest, shoulders or area you are wanting to protect from the sun.  This sunblock contains no essential oils, emulsifiers or water soluble compounds making it very stable and compatible with the skin or eyes.  If you perspire heavily when in hot work environments this sunblock will not sting the eyes if it follows perspiration down your face. Provides a full broad spectrum protection that will only decline with physical removal of the product from the skin through clothing friction or frequent wiping of the face or body while swimming or laying on the beach.  We recommend hourly reapplication. This Zinc Sunblock is completely clear and does not leave the skin with an opaque look.
