Obagi Professional-C Serum 20% (1 fl oz)

Love my Obagi. I have used it for years. Even today someone commented on my skin. Derm Silk, delivered in a timely manor. Thanks for being there!!

This serum is amazing. Saved me from acne years ago and since then I used it almost daily. Its realy good and the skin looks great.

I like it so far. This is my first time using vitamin-c serum.
