You should actually start using sunscreen in March when the first rays of sun hits your face. Or at least a moisturiser that contains spf. In june you need more protection and for me and my super sensitive and very fair skin that means spf 50 at least. Luckily Chanel hooked me up with their new UV Essentiel that filters out UV rays, free radicals and pollution. It’s lightweight and non greasy. I will keep one in my bag at anytime during summer.
