    Smooth and nice texture

    This serum is so nice on the skin absorbs nicely while quenching the dryness of the Midwest. Light to the touch but supple to the skin.

    Good product

    Love this product and how my skin is feeling

    Love this

    I use this every other night alternating with my Tret rx. I dab my face with water first then smooth on the hyaluronic acid then moisturize. My skin looks so much better and even toned. A dropper goes a long ways. No smell.
