I have the isntree Hyaluronic toner, the essence and also this Toosowong ampoule. And I find it really easy to incorporate Hyaluronic Acid into my skincare regime. When i use the toner as a first step, i pack on the blithe hydrating essence toner on top. When i want to use a light hydrating toner, I'll use the isntree Hyaluronic essence as a second step. Lastly when i want to use Hyaluronic Acid as a middle step after packed in hydrating toners and essences, I'll use this Hyaluronic ampoule and i kid you not they're all so good and work wonderfully for my currently dehydrated skin. I think I've finally reached a point of normal skin but i have to continue using these products for the winter months. Love this product, it soaks in really well and immediately and also works really well if you add a layer of the Toosowong propolis ampoule on top. Would highly recommend.
