Facial Sunscreen - Shiseido SPF 50 face sunscreen is my life savor. My face is extremely susceptible to sunburn and this product protects it. Beware though it is very thick and if you put to much on your face will be white as a ghost!
BB Cream or a Water Based Foundation - Lately i've been using Dr. Jart+ Black Label Detox BB cream and although its a mouthful, I really love this product. It is very light and doesn't make my skin feel oily throughout the hot days of summer. My favorite water based foundation is the Chanel Perfection Lumiere. Again it is a super light product with a little more coverage than a BB cream.
Translucent Powder - Completely obsessed with the Tarte Amazonian Clay Finishing Powder.
Cream Eyeshadow - This is a quick and easy step to brighten your eyes in summer. I use a bronzy metallic shade of Benefit called r.s.v.p but honestly any brand will do.
Clear Mascara - Going swimming but still want to give those lashes a boost? Use clear mascara! You can get a really cheap bottle from NYX or use any clear brow gel you already have.
Tinted Lip Balm - Keep those lips moisturized while adding a hint of color. I really like The Balm ever since I got a full size free at an event. It has a light shimmer and keeps my lips form cracking.
