If you need an alternative to fly masks for your horses with pink skin, I highly recommend KineticVet’s EquiShield SB! Willy requires 24/7 turnout at this point in his life and is very prone to sunburn and blistering. For several reasons, his fly masks were no longer an option. After just one week of using EquiShield SB (applied daily for 3 days,then every other day for 4 days due to rainy weather) the scabs and blisters are gone and he has a nice healing, pink nose. This is a great product.
