A light moisturizer is a must when you are overheating every day. While you don’t need to carry it with you, make sure you moisturize every evening. Your hands and face are particularly important, as they bear the brunt of the sun each day. Apply a little in the morning under your primer to ensure your skin is protected throughout the day. Select a light lotion that will be absorbed rapidly into the skin. Tinted moisturizer eliminates the need for foundation and can simplify your makeup routine.
