Solid product, but a bit too strong for my skin. I found the 15% to be better suited for me.
Love this Obagi product. The people at the store even waited so I could pick it up same day.
Definitely one of my favorite vitamin c products. I did not find it hard at all to transfer to the 20% level. 7 drops covers my face and neck. I love pressing it into my skin! It definitely gives me brightness and glow. Well worth the price and it lasts a long time. There is no adverse smell like with some other vitamin c products.
I use this Vitamin C because of its price point. I notice a change in my skin when I use it. However, the dropper is pure crap. I’m on my 3rd bottle and on everyone, the black rubber top comes out. Not good but yet I keep repurchasing. Again, fantastic serum but terrible packaging. Hope they fix this!
This is a really good Vitamin C product with 20% L--ascorbic acid. It needs to be kept in a cool dark place so that it doesn't oxidize too fast. The dropper is good, though sometimes I find it doesn't seal well. I would repurchase, however, my skin likes Tetrahexyldecyl Ascorbate better.
