Supreme Products Highlighter Gloss. The Supreme Products Highlighter Gloss is used to produce a glistening finish and enhance your horses’ natural pigment colour when additional preparations are not required or allowed. The Highlighter Gloss is lighter in texture then the gel yet still provides a fabulous finish on the eyes, nose and dock area. A UV sun protection filter has now been added to help prevent sun burn and will become more glisteny as the horses natural body temperature warms it up. For additional results, Highlighter Gloss can be used over the top of Supreme Products Make Up to achieve a glossy finish!
