    Love

    I’m so happy I made the switch to Blair Skincare. I currently use the Tonic and Vitamin C 20% Serum. I absolutely love both products. My face is glowing.

    Favorite vit C serum!

    I was using another medical grade vitamin C serum that had a formula change. The new formula broke me out so I decided to give Blair’s formula a try. I’m so glad I did! This serum is acne safe and leaves my skin more radiant.

    I have tried so many vitamin C's in all my years on earth and this is by far the best! I love every single thing about it. Especially the way my skin glows.
