During the day, your skin suffers endless environmental aggressions: stress, pollution, tobacco, UV... the list of free radical-inducing factors goes on. It produces waste that it must eliminate to be on top form. If toxins accumulate too much, skin cells start to dysfunction. The result: a dull complexion, dehydrated skin, wrinkles, spots and red patches. It is when we sleep that the skin gets to work to repair the damage done during the day. During this process, the blood circulation to the skin is stronger, in order to provide the nutrients needed to get rid of these toxins. Night creams boost the cells' cleansing system to deep-clean the skin and eliminate the particles that make it dull.
