Best Vitamin C
Love this product and it does not seem to irritate or break out my acne prone skin. I definitely feel like my skin is brighter when I am consistently using this product.

Love the Blair Vitamin C
I have been using this daily for over a year and love what it does for my skin and how it makes my face feel. I use it first thing every morning after a gentle face wash. It does not dry out or irritate my skin and is a great base before my moisturizer. Cannot be without it.

Simply the Best (as Tina sang it)
I’ve used Obagi, Sunday Riley, and now Blair’s Vitamin C. I love Blair’s the best. The combo of the 2 derivatives plus the extras make this truly remarkable. My skin soaks it in, it is moisturizing and most of all, effective. Thank you!
Love,
A Tonic, Ret+ and now Vit C fan. 🥰
