Protekt Sunscreen is the perfect water/sweat proof barrier to protect you from all the harsh conditions you will face outdoors. From UV rays, to wind burn, to dry climates, our moisturizing formula will keep you covered with a physical barrier of organic zinc oxide. To maximize its effectiveness and your outdoor time we recommend rubbing our products onto your skin in a circular motion as you would a normal lotion.  If you wish to make the product more visible on your skin, you can then finish with a second visible layer.  *Note: the layer of Protekt does not need to be thick – just rubbed on and spread evenly to the areas you want to protect. Zinc is a physical barrier, so even a light coat will go a long way!  We recommend following FDA guidelines and reapplying every 80 minutes for maximum protection.
