I would give 6 stars if I could on all the Equiderma products I've used thus far! Most recently, the zinc oxide paste has been super helpful to help protect my horse's face from the searing sun! And I've also been using it to protect the tender tissue of the incision on a client's horse who had kissing spine surgery in June. Protecting that tender skin from the relentless sun so that it can properly heal has been a big priority...& as this horse transitions back to more turnout, I can rest easy knowing that the zinc oxide paste does not melt easily & stays in place while being impressively effective! thank you!
