The use of nutraceuticals to improve skin properties and decelerate skin aging has been gaining attention among dermatologists, over the last years. In this article, we are presenting the theoretical scientific support for Yuliv TM Collagen Drink, a liquid supplement containing bovine type I collagen peptides, ascorbic acid and Camellia sinensis (green tea) extract and its benefits on the skin. The available literature shows that the ingredients contained in the supplement have the potential to improve of skin hydration, dermis collagen density, and decrease the fragmentation of the dermal collagen network—and therefore reduce wrinkles and sagging and improving elasticity. Additionally, other health benefits could also be observed, such as protection against oxidative stress, contribution to the normal function of the immune system and reducing tiredness and fatigue, and reduction of skin inflammation, improvement of elasticity and prevention of oxidation. For those benefits to be visible, it is likely that continuous use of at least 4 weeks is needed.
