A moisturizer in which there is a greater concentration of hydrating ingredients than typically used in day creams. There are two reasons why a night cream is important 1) TEWL (trans epidermal water loss) is greatest at night. A night cream can prevent that kind of dehydration. 2) the body’s cell are replenished with nutrients and are being regenerated at night, so this is the time to optimize the delivery of the raw materials the skin needs.
