Airbrush Makeup Tip?

We are getting married in New Orleans on August! Photos are outside, 5 hours before the wedding. Are any of you makeup artists? I need tips for how to touch up makeup after photos in the heat! Do we blot the sweat and then apply a translucent powder? If so, what specific brands and or products do I need to have on hand? Also ant lipsticks and lip glosses do you love? And specific colors? Bridesmaids are mostly fair skinned blondes, one olive complexion brunette, and a medium/brownish skin with black hair.
I have asked the makeup artist and she isn’t answering this question.
