I often use both, layering together for the ultimate nutritive cocktail, though they can also be used alone. I like The Youth Dew for daytime and The Blue Cocoon for evening, indulging in both day and night together when my skin is craving a little extra love (nearly always!). It's hard to summarize succinctly, but I reach for The Youth Dew for graceful aging protection, to help balance oil production and keep skin clear and to load up on antioxidants and vitamins. I reach for The Blue Cocoon because it has literally saved my highly reactive and sensitive skin. For me, it's medicine. It's my first choice for clients struggling with any redness, inflammation, discomfort, allergy, trauma or simply when your skin needs a hug. This said, The Blue Cocoon is magic even for those blessed with perfect angel skin, performing as the world's best facial oil in a pretty blue balm costume.
