This is the best tinted moisturizer/foundation I have ever used.No matter what the weather is, this will never slip off your face, settle in your wrinkles or give you pasty face or make you break out.The coverage is light and natural for daytime and build-able for more coverage at night. Team up the tinted moisturizer with the foundation primer and you have a winning duo that lasts all day! I have lived in the Mojave Desert and in Hawaii, extreme temps, and Laura Mercier Oil-Free Tinted Moisturizer worked great. No complaints.
