    Nice serum

    A great hydrator my only issue is the short open life of 6 months. But applied to damp skin with the dewy mist it spread and absorbs wonderfully.

    Good price

    Just started using the Inkey Collection so too early to tell if it works but what I can say is I am hopeful and I like the textures of the products so far especially the cleansing oat balm 😍
