The difference between the way your skin acts when you wake up and around the time you go to bed is somewhat like that between night and day, and it's important to observe these disparities when selecting the thickness of the cream you wear.
According to ELLE.com, it's not the best idea to use super rich moisturizers during the day time in the summer, but heavy night creams are definitely well-advised.
"Heavy creams can create a barrier on the surface of your face and keep your skin from absorbing moisture," the news source explains. However, "there's evidence that skin-cell regeneration is slightly faster at night than during the day, so take advantage of your skin's receptiveness and don't skimp on overnight hydration."
Of course, this goes for the rest of your body as well. To really maximize on the power of beauty rest, lather yourself in a rich body lotion before going to bed.
