Obagi Professional-C Serum 20% infuses your skin with L-ascorbic acid, the only form of vitamin C suitable for topical application. Designed to penetrate deep into your skin, this vitamin C serum provides effective antioxidant protection from UV damage as it brightens away hyperpigmentation and encourages the growth of collagen and elastin fibers. Hyaluronic acid binds moisture to your skin to prevent dryness.
Apply 5 to 7 drops of Obagi Professional-C Serum to the face, neck and chest using fingertips. Apply to cleansed skin in the morning before sunscreen and makeup application. A slight tingling may occur in some people, which diminishes with continued use.

The only C serum I buy
It's hard to find a 20% high quality C serum. I've been using it for years and love it.

Delighted with this product. Saw a change in texture of skin within 5 days as well as smoother foundation application

I have been using Obagi C-Serum 20% for about 3 weeks now. As of today, I have not noticed any significant changes in my fine lines and wrinkles yet. I do notice a glow and a smooth skin tone when with this product so that is a plus! I will follow-up with an update in a few months.
Report this reviewBest C Serum on The Market!
I have been using this for years. I have tried other serums but always go back to using this one. I get so many complements on my skin when I am using it and have turned on several family members and friends on to it. I cannot recommend this product enough!!

This is the only product that changes my skin. I’ve tried all the “dupes!”
Report this reviewBest Vitamin C serum
I am a dedicated Skin Medica person BUT I love Obagi C Serum 20% . It smooths my skin, shrinks my pores, and lightens the dark spots. It is my Vitamin C serum.
Report this reviewA must have!
This is a product that I can't go without. No sticky like others I've tried. Pairs well under my make-up. Has made such a difference in my aging skin!
Report this reviewThe GOAT of skin care products
This serum is absolutely the GOAT. If you only used one product, this should be it. It softens and reduces fine lines and wrinkles. Improvement is noticeable after a few days of use. Highly recommend.
