The texture of this serum is light and just slightly more viscous than water. This product combines the power of niacinamide and vitamin C in one sensitive skin-friendly formula. Sea buckthorn is not only rich in vitamin C, it also has vitamin A, vitamins B1, B2, and B6, vitamin E, omega 3, 6, 9 and 7. It is incredibly nourishing to the skin. On top of that, it also helps regulate oil production and has antibacterial properties. I really love the formation or this product.
