Solid Product for Price
L-Ascorbic Acid is the most highly-absorbed form of Vitamin C, which is the ingredient in this product. The product is definitely better priced (especially with a frequently-occurring discount) than some similar Vitamin C products. As you apply, it has a slightly sticky feel that is very mild and doesn't bother me. It seems to dry quickly so you can move onto your next skincare step - the sticky feeling doesn't "stick around," pun intended. This product has a slight citrus-scent. My only complaint is sometimes the dropper is messy and I lose a bit of product, so I have to be extra slow and careful to save drops.

Glowing skin
I was skeptical of using the 20% because I have very sensitive skin. Very prone to eczema breakouts with products. This serum has been amazing for my skin! My skin was dull and dehydrated before, and I use top of the line expensive skincare!! This serum has changed my skin. It's hydrated, glowing and so, so soft! This has changed the texture of my skin 100%. I'll always keep using this product!

Great Vitamin C Serum
I've used Obagi vitamin c serums for about a year now and love them. I started at 15% and just tried the 20%. It works well and hasn't caused any irritation.

Love!
Since using the Obaji C Serum 20%, my skin looks so much better. I was skeptical, but it really does make a difference with your skin. Its worth every penny and lasts for quite a while as well.

Obagi Professional-C Serum 20%
I have used the Obagi Professional-C Serum 15% and thought I would give the 20% a try. I have noticed and big difference in my skin tone, elasticity and general overall appearance. My skin tone is so much brighter and more youthful looking. My husband commented that my face glows and looks great. I have fewer wrinkles as well. I hardly ever wear makeup anymore as my face and skin look fabulous and has a natural glow. Thank you Obagi.

Rejuvenating Formula in a Bottle
Just few drops and lets the skin firm, erase fine lines and give a radiant appearance. This is my second bottle! Love Obagi products, specially for my sensitive skin.

Been using Professional C Serum 20% for over 10 yrs. It totally brightens & smoothes my skin. Evens out the texture. Love all Obagi skin care.

my favorite
I've been trying my best to take good care of my skin during quarantine. I have read the benefits of adding vitamin C to my skin care routine. I've tried multiple brands but Obagi is my favorite. I like the way it applies. Not too greasy, not too drying. It has done a good job of evening out my skin tone when I've tried to limit the things that can make my dark spots worse in the sun and heat this summer.

Nice serum
Nice consistency, packaged well. I use this under my sunscreen and it makes my skin look brighter! Only downside is it has fragrance in it which it could have done without.

Best Vitamin C
I started using this serum about six months ago and since then the spots on my face have diminished and I don't even wear my BB Cream anymore. This serum gives you results!

Obagi Professional C-Serum 20%
This is the best C-serum I have used. I am on my third order because I have found that it works!!! I can`t say enough about this product. It is very hydrating, age-defying, decreases the appearance of lines and brightens the skin. I highly recommend it!!!!

The best.
This serum the best thing that happened to me. I have bought many serums from big or famous brands without changes. My face looks radiant with closed pores and the spots have cleared up. Excellent I recommend it.

Best ever!
This was a recommendation from my dermatologist years ago. I have used it ever since. It fades uneven skin tones common with age. I definitely notice a difference when I run out and think, “do I really need this?” Yes !!

Excellent Serum
I have tried many Vitamin C serums and this has got to be the best. It glides on my skin easily and goes well with my Hyaluronic Hydration. I can really tell a difference with the brown spots on my face. They are getting lighter and lighter. I will continue to order this C-Serum because there are very few with 20%.
