Best Vitamin C

5 stars out of a maximum of 5

I've used several different vitamin c's and this is by far my favorite. It's so silky on your skin and my skin glows afterwards! I will forever continue to purchase this!

Best Vitamin C

5 stars out of a maximum of 5

This is my favorite vitamin c product! The 20% is strong and delivers results. I've noticed less hyperpigmentation and overall improvement in the texture of my skin. This is a product I never go without!

Never go without

5 stars out of a maximum of 5

This is one of those products in my skincare lineup that i will always repurchase. I believe in medical grade vitamin C and Obagi does it so well. I get nervous everytime I'm nearing the end of a bottle hoping that my next shipment will make in time for me to never go a day with out.

Upgraded from 10 to 15 to 20% now

5 stars out of a maximum of 5

I started with the 10%, then 15% and at 20% to build my skin's tolerance. It is easy to absorb and leaves the skin with a nice glow.

Dermatologist recommended Obagi Professional C serum 20%. I use daily and it takes care of dark spots. Recommend highly.

Love this product.

5 stars out of a maximum of 5

I have used this product for many years and I really like how smooth my skin feels each time. However, Dermstore is very slow with sending products. I have used them for several years and it always takes AT LEAST a week to receive anything. When I eventually receive this particular product (based on the estimated arrival), it will be TWO WEEKS from my order date. So, if you buy from this company, be sure to plan well in advance to receive anything. Other than this issue, the Obagi products are very good. I have used them for ten years.

If I were on a deserted island

5 stars out of a maximum of 5

And I could only bring two skincare products with me. it would be this AMAZING professional-c serum. I've been a loyal customer of Obagi and this serum has maintained high quality ever since. I have combo/dry skin, I'm in my mid 30s and I live in California so I'm in the sun often and skin is important to me. You will love this product if you purchase.
