Good formula
This is my 2nd best fav C serum and a go-to when price is a factor. Obagi definitely nailed one of the top C serums on the market. Feels like it's working from the moment you pat it in.

It's a must in your daily routine!
A doctor recommended Obagi years ago and I have been using the C serum 20% for years now and am so happy with the results!

Vitamin C + great for my mature skin
I'm in the high desert of the Southwest. I use a few drops each morning and evening before moisturizer.

Cannot Be Without It!
Every time I stray from this product to try something new – typically a high-end new release – I come back to this one. And to be honest, I’m usually nervous while using something else. That’s because this one has been such a reliable, effective, integral part of my routine. I’ve used it daily under sunscreen for about five years now. It absorbs quickly and cleanly. It has a slight green apple scent. The other plus for me with this product is that it does not contain Ferulic Acid, which can trigger rosacea. This is just straight up vitamin C as the acid, which is all that’s needed. It’s one of three products that I credit with keeping my skin in exceptional condition. I seriously get compliments a few times each week.

Great product!
I’ve been using this for about a month now! I love it! I’ve had comments on my skin. It blends in well and layers perfectly under my sunscreen and makeup! I will definitely buy again!

It’s Working!
I had been buying a lower percentage of Vitamin C and wanted to up my regimen. The first few tries, my skin felt irritated and red but after 2 solid weeks of using it, everything is going perfectly.

Great Product
Have used Obagi 20% C-Serum for many years and love it. Keeps my skin even and protected. My skin gets lots of sun (use hat and sun screen always) here in AZ plus I walk several miles a day. This products really helps my skin. People think I am 20 years younger than my age. Using good products (like Obagi 20% C-Serum) keeps my skin in great condition. Would not be without it.

Incomparable
Obagi Pro-C Serum 20% is the only brand of Vitamin C I'll use. I've experimented with others, but nothing compares. I'm constantly asked what I use to make my skin look so great and this is the product that does it.

Fantastic Vitamin C Serum that Makes A Difference!
I ordered and have been using this Obagi Vit C product and just love it! I’ve used another high end, popular and more expensive one over the last several years. This is just as effective and maybe even more! Absorbs quickly into the skin and leaves a natural radiance. This will be my new Vitamin C Serum of choice going forward. Try it, you will be happy with the results.

Best Vitamin C product
I have been using the Obagi 20% Vitamin C for years. It gives you a nice healthy glow. I've used other Vitamin C products and they would give you an unnatural yellow/brown look on your face. I use the Obagi one every morning. I love it!

Obagi Professional C
Obagi Professional C Serum 20% is my go-to every day. I love it! It has kept dark spots from appearing and faded others. It has also made deep lines less noticeable. Of course I have been using it for a long time and the results have seemed to build more with time.

On my second bottle…
Purchased first bottle because of reviews and recommendations. Already onto second bottle. There’s something glowy about my skin and now that it’s part of my routine during the day…I’ll keep using it.
