"The most important part of your beauty routine everyday after removing impurities is to put a protective, plumping barrier layer of moisture against your skin. This helps the skin protect itself from environmental damage, prevent too much moisture loss through evaporation and keeps surface cells translucent, keeping that glow of youth shining through when light hits your skin." Say, Dr. Jessica Krant, assistant clinical professor of dermatology at SUNY Downstate Medical Center New York.
