DIY desert wedding makeup

Hi all, I am getting married in the middle of the desert this summer. I used to be quite the makeup connoisseur but swapped that out to get fully into skincare for the last 8 or so years, so I need some help.

I’m looking for advice on best makeup lines or best products for foundation, concealer, and maybe powder that lasts all day and doesn’t melt when I sweat.

I also have the tiniest lashes ever and was considering fake lashes but the glue gets really itchy at the end of the day so if you have alternatives here, I’m open to any and all suggestions!
