Description
Obagi Professional-C® Serum 20% provides ultimate antioxidant protection and instant radiance. Suitable for normal to oily skin.
Obagi Professional-C® Serum 20% is the highest concentrated Vitamin C serum in the Obagi Professional-C® range.
A strong and powerful formula, Obagi Professional-C® Serum 20% helps reduce the appearance of fine lines and wrinkles, evens skin tone and retains skin moisture, giving you a brighter, healthy-looking complexion.
With 20% L-ascorbic acid (the most potent form of Vitamin C) to help calm and brighten skin, as well as retain moisture, this facial serum gives you an instant glow without leaving skin feeling greasy. Best suited to normal to oily skin types.
Did you know? Free radicals break down your skin’s collagen and elastin which results in premature skin ageing – the cause of fine lines, wrinkles and dark spots. Vitamin C stimulates new collagen production, reduces fine lines and wrinkles and protects your skin from harmful free radicals and UV exposure.

It took a little bit to get used to this serum, but I see great results from it. My skin is a lot firmer and glowing. It’s great for finer lines, and I could see an improvement after a month of using it.

This is hands down my favorite vitamin C. After trying numerous others, starting with 15%, and then working to 20% I’ve finally landed on this as a keeper. Great price point as the bottle lasts forever.

I got this for myself because I have very oily skin, and other serums I tried before didn’t really do anything for me. I am a happy customer with this serum, my skin absorbs it quickly, and my expression lines are smoother. My sister tried for a couple of days but her skin is dry, so it’s not good for her; I bought the 10% for her, and she is also very happy.
