Best Vitamin C Serum!

5 stars out of a maximum of 5

This is a great serum to apply in the morning to a fresh face under moisturizer and sunscreen. It adds an extra layer of protection from UV damage and has definitely improved my skin tone, especially improving hyperpigmentation from years of sun damage. A must for your skin regimen!

Professional-C Serum 20 by Obagi

5 stars out of a maximum of 5

Love the product! Have purchased it multiple times. The bottle does turn over very easily as the base is super small so do be careful our your serum can end up all over the bathroom counter!

Best vitamin C serum

Has really helped shrink my pores and gotten rid of my melasma. I can feel it working when I put it on, in a good way!

Love Obagi's Vit C serum!

5 stars out of a maximum of 5

I've been using the 15% Vitamin C serum and have gotten so many compliments on how much brighter my skin is looking. Excited to start using 20% now that my skin tolerates it well!

Decently priced compared to competitive alternatives, and noticeable results within months. Not sticky like other vitamin c serums I've tried

Holy Grail Product

5 stars out of a maximum of 5

This is my can't-do-without product. I use it every couple of days and it noticeably minimizes my pores and prevents breakouts. I am so so happy that this product was recommended to me.

Good product

3 stars out of a maximum of 5

THis is a good product, but not worth such a big price tag. I used the whole bottle and really didn't notice a difference.

My dermatologist suggested I get a top grade vitamin C serum and recommended Obagi and it has not disappointed! It feels great going on and I've seen a positive change in my complexion! Highly recommend!

This serum is outstanding, and helps with keeping my skins smooth, less wrinkles, and overall age-defying. I wear it every day under my moisturizer. Love love love it!
