Omg! The Good Molecules B5 Hydrating Body Serum is a must-have! It is a moisturizing body serum with B5 Panthenol, Polyglutamic Acid, and Beta Glucan. Refine tone and improve texture all over! Perfect for keeping your skin hydrated all Summer! It is so lightweight and my skin always feels so smooth and hydrated after using it . I usually mix it in with the lotion I use or use it on its own. I highly recommend it! Love, Cristina
