I love Joanna Czech. I see her every few months for a facial. She can do no wrong, so if she tells me to use something, I will use it. She is also someone who doesn't like to use products that are not science-backed, so, of course, when she came out with a skincare line, I stood behind it. The C+ Serum is absolutely amazing. It brightens, it evens out the skin, and it really seeps into the skin instead of sitting on the surface.
