The heat is definitely on! It's funny, but I keep getting asked, "What style of makeup should I wear in the heat?" Well, I can relate to both East and West Coast. As, you all know yours truly is from Miami, FL where humidity, heat and rain at times can be unbearable, to LA, where you have the dessert, dry and sunny California environment. There's one key to makeup in the heat: WATERPROOF! Makeup that is water resistant will help you be able to create looks during these high summer temperatures. No smudges throughout the day whether you are on the beach or in the hot muggy city. Depending on the humidity in your city... Try choosing products oil-free, using powder or tinted moisturizers, and this will let your skin perspire naturally.
