Luminesce Cellular Rejuvination Serum by Jeunesse is the flagship product of their skin care line. To maximize usage, lightly spray your face with water before applying the Serum. Apply to your face, then your neck, and then spritz your hands with water and use the remaining Serum on your fingers and palms to rub into the backs of your Hands. I have had a severe sensativity to any products I have tried over the past two years since developing Atopic Dermatitis. Luminesce is the first product I have been able to use without having any Problems at all.
