Equiderma Zinc Oxide Paste is a powerful specialty treatment for scratches (pastern dermatitis) and sunburn prevention. Your secret weapon in the battle against Pastern Dermatitis (aka scratches, greasy heel, dew poisoning or mud fever), creates a protective barrier so pasterns stay dry and safe from irritation and infection. Contains many of the same ingredients as Equiderma's popular Skin Lotion, but in a thicker consistency, with added zinc oxide to dry and treat seeping trouble spots. Surprisingly, preventing UV exposure is an important factor when battling pastern problems resulting from ultra violet light sensitivity; the paste provides 100% sunblock so it can also be used to protect your sensitive, newly clipped, or light colored horse from sunburn. Protects and soothes cracked skin resulting from cold weather conditions or prolonged moisture exposure
