Better than others
This C-serum does not darken as quickly with age as others. It is very powerful and works well for removing puffiness under eyes.

best on the market
I have used different brands of C-serums over the years and found with my sensitive skin Obagi works the best with no problems and i do see results.

Protects with antioxidants
C-Serum is part of the best home skin renewal program ever, because it takes place deep below skins surface. I keep mine in a cool, dark place to help keep it stable and active to the last drop.

Great product
I ran out of this about a month ago and thought I'd see how things went without it . . . I definitely missed it, and can absolutely see a difference in my skin when I use it. My face feels a little tight, (but in a good way!)when applied, and by the next morning I have increased smoothness in my skin texture. Over just a short amount of time, the difference is quite visible. It's a must in every skin care regimine!

Amazing
This is my first time using the Obagi Professional C-Serum 20%. It's been about 3 weeks now of usage and I see a difference in my skin. Any Obagi product is worth its weight in gold.

There are alot of C-Serums
There are a lot of C-Serums out there but there is only one I would rate as the best "Obagi Professional C-Serum 20%", after trying at least half a dozen since the first Announcement of the benefits of Vitamin C my skin burned itched and my Chin would always brake out. After one of my Microbrasions I was given a sample of Obagi C-Serum and have had no problems with the product even with my sensitive skin I had no break outs or itching as other Vitamin C Serums in the pass.

Love the C-Serum
Even though my skin is very sensetive, I use this twice a day all over including my neck area. I love the feel and look of my skin after ten years of usage with all of the Obagi products.

For Ance
I have been using this for more than 6 months. I used to use the less% of this series but wasn't satisfied and still had some acnes. Since I started using this, my acne has been getting less and less! Especially, under neck acnes!!! Of course, I am using other products for acne with this too. If you are suffering from terrible acne and spots, it worth to try this highest % Vit.C serum!

This is a great serum
This is well worth the investment. I could see the difference in my skin in a matter of a few days. Goes on nicely and absorbs into your skin without a residue feeling. You only need a few drops so a little goes a long way.
