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.

C serum

This is my favorite C serum. I have been using this product for a few months. I use it before moisturizer. I like the way it softens my skin.

Love this product!

I do love this product and have used it for years. I'm 73 and most folks guess that I'm in my early 60's. I use this almost daily. I like that you are offering it in a smaller container, which is perfect for travel. I've used Obagi products for many years now because my dermatologist recommended it. It leaves your skin feeling smooth and brightens over time.

Amazing!

The Obagi Professional-C Serum 20% works wonderfully! Helps with acne scars and really brightens my skin. I have also gifted my mother, who really notices a difference in the clarity and brightness of her skin. I love that Obagi has sales on their amazing products.

My very favorite

This vitamin C is one of my favorites. It’s been a part of my skin care ritual now for fifteen years and my skin has reaped the benefits.

Great product, great results

I have been using the Obagi Professional-C Serum 20% for a few weeks now. The 20% is higher than the previous C product I used. I am noticing a difference in my skin clarity and a reduction in the fine lines and wrinkles, especially around my mouth and eyes. If I'd known how great this product is, I would have switched a long time ago!

Obagi Progessional-C Serum 20%

I had been using another VitC serum for over 25 years and was gifted by a friend the Obagi Pro-C 20 this past year. To my surprise, this is a really, really super product. I even purchased it instead of my tried and true. Thanks!

Great product!

I've been using this product for several years now. I am 64 and try to use the best products available. I think this serum is wonderful. I definitely have noticed improvement in my skin over the years. It really helps with fine lines and pours! Highly recommend!

Vitamin C

I have been using vitamin C for years and I thought my brand was good until I tried Obagi. This is a game changer. I have had more compliments on my skin then I have ever had.

Great vitamin C

I’ve been using different brands to test the quality and results of the. The first time I tried this one was about 6 years ago, from there I have been changing or trying others, the ones on trend, cheaper, more expensive, easy to find on Amazon… you named it. But every time I come back to obagi C serum 20%. My skin feels smoother and looks brighter. I don’t know if I’m going to keep testing other brands but for sure I will always come back to obagi.
