I agree, using a decent quality primer is definitely an advantage with these hot days and makeup. Another thing to try is a water resistant foundation which will help your makeup stay put in conjunction with primer use. Lastly, how high up are you putting on your makeup? Don’t go any higher than your eyebrows when applying makeup, I got that tip from a makeup product company owner/artist on TV one day. I find that when I do sweat, most of the perspiration comes off my forehead and there’s no makeup there to worry about. The little bits of “beading” that do occur on the rest of my face I just gently dab with a tissue and if you watch what you are doing then you can get through the day with hardly any touch ups also.
