It is has consistency that is non-sticky. Dry, sensitive skin is soothed and moisturized by the Hyalu-Cica element of this serum. By revitalizing the skin's surface, niacinamide and adenosine brighten the skin and reduce wrinkles. I really like that it has a pump as it is easier to control the amount of product.
