For a long time we have been trained to believe that hydrating ingredients like humectants are a necessity for the skin. Common ingredients like glycerin, hylauronic acid, copper pca are thought to be a big drink of water for your skin. However that wonderful humectant included in your moisturizer could be draining the moisture from your face.
Humectants bind water and if there is no humidity in the air the humectants can actually pull water from skin! Beware of plane travel, winter and dry states. If any of those apply to you, you may need to avoid humectants and go with a true moisturizer with an oil or silicone base. Who knew we need change our moisturizer depending on the state we are in?!?
