A keeper

5 stars out of a maximum of 5

I had read that Vitman C serums improved and protected skin. I drug my feet trying it as I had a little sticker shock at the price. I purchased during an Obagi sale and it is a forever staple now in my regimen-several people have commented on  the glow of my skin and I have seen a significant improvement in texture and healthiness of my skin.

Best part of my skin routine

5 stars out of a maximum of 5

I use Obagi Medial Professional-C Serum 20% daily. It is the best part of my skin routine. It keeps my skin plump and bright. If you have never used the 20% strength, I recommend you start with the 10% and then work up to 20%. This is a truly great product that I will not go without.

Favorite Vitamin C

4 stars out of a maximum of 5

I love this formulation. The 20% is strong. If you have dry or sensitive skin you may want to start at a lower concentration.

2nd time purchasing!

5 stars out of a maximum of 5

the 20% is amazing and I will continue to purchase. A bottle lasts about 6 or 7 months which makes the price not feel so bad.
