Highlighter (makeup) help!

Ellie

I've recently discovered that I love using highlighter on my cheekbones and the tip of my nose, and I'm practicing my makeup look for a meet and greet I'm going to in a few days. I will be taking a picture with shawn mendes and I want to make sure my highlighter doesn't make me look greasy. Will it look shimmery or greasy? And any tips to prevent it from making me too shiny?
