This is my second order of these products. I started off with just the Vitamin C serum. It really made a difference, both to the texture of my skin and to small discolouration due to the odd spot. It sinks in easily and didn’t leave my skin feeling overwhelmed with product. I’ve now added the Ferulic Acid and Hydra B5 serum to my routine. I’m a month in and my skin feels and looks wonderful. Everything absorbs quickly and is light on my skin. Im delighted with all the products.
