Makeup Setting Sprays

I got my first internship, and I am so excited! However, some days I will have to be outside, and its near the beach so it will be very hot and humid. I don't wear makeup super often, but I would like to make an effort this summer and it helps me feel more confident when I have a little on. Any tips to make it last 10+ hours without creasing or melting off my face would be greatly appreciated! Also any recommendations about what I should wear or styles I should try! I usually just do concealer, blush, mascara and a skin tint if my rosacea is bad or I am breaking out. I don't love heavy makeup on myself because I am not use to how it looks on me and with the weather I think the lighter weight it is the better!
