Say Whoa! to sunburnt noses. Your horse's unprotected skin is just as tender as yours is. Zinc oxide is known to provide a total sunblock to skin and hair. Our balm helps keep skin soft and supple while protecting from the sun. Rub it on the skin where sun protection is needed and apply as much as you need to create a white surface. Our sunblock will stay on until it is washed or rubbed off.
