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.

Purchased again!
I have tried many vitamin C serums and this product is by far my favorite. This is the only vitamin C serum where I have noticed a difference in my complexion within a few weeks. Definitely worth the price!

better than Skinceuticals
I was wooed by reviews and tried Skinceuticals CE Ferulic serum for six months, and the results were not nearly as impressive as Obagi's 20% vitamin C serum, which is significantly less expensive! I use 7 drops on my face and neck every day, and my skin has never looked so clear, bright, and smooth. It's impossible to go wrong with this serum; if you're looking for a trusted formulation, this is it.

Not real product!!!
I've been using this serum from Obagi for years and when it's the real thing it's amazing! I've ordered it in the past from dermstore and I had no issues but this time it's not the same. I've been warned of this by dermatologists. The smell and color of the serum is completely different with this last order and even the label color was slightly off. I'll definitely go back to ordering it straight from Obagi as the price was just about the same. So irritated and extremely disappointed!!! Goodbye Dermstore!!

My favorite Vitamin C
I have sensitive and dry skin, which makes finding skin care products harder. I was worried I'd get red around my nose/mouth area when I tried this, but it's very gentle on my skin. I didn't feel any tingling sensation. My face was brighter after wearing for couple of days. This is the only vitamin C I'll wear.

Expensive, but effective
This is loaded with so much vitamin C, so this must work. But, this one has fragrance in it. Maybe it's not for the sensitive skin type.

Alcohol?! No thanks
Alcohol - not the kind that is prefixed with a word ending in -yl and henceforth a hydrating alcohol - is the fourth ingredient. I would never in a million years use this when there are so many other C serum choices that work just as well and don't contain drying, barrier destroying ALCOHOL!!!

great product
I felt a slight tingle during the first dew applications. I use it AM and PM. Overall skin texture has improved. Slight dryness over peri-oral area. Few PIH scars have lightened. Its been two weeks since I started. I have used Image/Epicuren/Skin ceuticals products before with very little difference on skin. Obagi 20% has made a difference to skin.I will be re purchasing this.

Amazing vitamin C!
I've only been using this for two weeks and already notice a significant difference in the brightness of my skin! Goes on smooth and doesn't give the tingle that other vitamin C products do. Highly recommended!
