I have been using this sample for a few weeks now, and have absolutely loved the results. I adore the Silymarin CF, and with aging combination skin I was a little worried that I may end up shiny by the end of the day. There was absolutely no need to worry. The CE Ferulic brightened and evened my skin tone, and my skin looked hydrated throughout the day, but without the shine of excess oil. It sat wonderfully under my makeup, and I am so pleased with how healthy my skin looks and feels. 💫 Also thank you SkinCeuticals for a really good sized sample. I was able to wear for three weeks, to not only see the instant benefits to my skin, but also the cumulative effect of everyday use 💫
