The earlier you add a vitamin C product to your routine, the longer your complexion will remain youthful and radiant. Obagi Professional C Serum 20 is a concentrated serum with 20% vitamin C that provides multiple benefits for the complexion. This ingredient neutralizes free radicals that break down collagen and elastin causing damage, leading to fine lines, wrinkles and dark spots. Vitamin C also promotes collagen production which plumps skin and reduces the look of wrinkles. The formula is ideal for most skin types and it absorbs quickly without leaving the complexion greasy or oily.

Obagi C serum
I don't go a day without my serum and this is my go to. I have been using it for 20+ years. I gifted one to my friend to get her started on a good regime.
Great product
Excellent product which helps maintain humidity and diminish wrinkles
Excellent product
I’ve been using this product for over 10 years. I started with 10% and bumped up to 20% to let my skin get used to it. I use on my eyelids! It’s a great anti age product and staple in my routine
Great product!
I have used this product for over 10 years. I even use it on my eye area after I built up using the 10%. It’s been a foundation and staple in my skin care, and takes care of making my skin even toned and exfoliated. Love it!
Obagi C serum 20%
I have been using Obagi products for years. I am constantly complemented on my facial skin. The investment in the Obagi regime is well worth it
Look out for oxidation
My bottle came yesterday with a slight tint of yellow. Isn't it just heart breaking to pay so much for this little bottle, just to see it's already on its way to oxidation? I won't question the freshness of skincarerx stock, but my order took over a week to arrive. Obagi vit C is said to oxidize quickly, and this summer heat definitely has helped it out. Something for potential customers to consider. Next time, I'll consider a better shipping option.
Obagi C serum 20%
I have used this for quite some time. I would not be without it. It has really helped my skin with dark spots and roscea.
Obagi 20% Vitamin C
This product seems to be working well. I'm new to Obagi, but like it thus far. The scent is strong at first, but does not linger long. Overall, a good product.
Spot remover
Love this product!had an age spot on my cheek. Could hAve tried to have it removed with a laser, but I tried this instead. It lightened the spot up to the point where it is barely visible!
