Dry skin can be caused by various factors, including age-related thinning skin, which can lead to increased transepidermal water loss; environmental factors such as cold, dry air, smoking, sun damage; and certain medications, according to Ryan Turner, MD, a board-certified NYC dermatologist and co-founder of TRNR Skin.

This thing is a paradox: super rich but not heavy. My skin is dry—so dry that the last time I went to get a facial (through work), the esthetician was surprised my skin drank all the massage cream and she needed to reapply. :P This is the best moisturizer I’ve tried (and I’ve tried so many in the past year). Not greasy, not oily, but incredibly moisturizing.
