OBAGI Professional Vitamin C
I have always used the highly sought after competitor Vit C Serum & thought I'd give this a try & I have to say I love it!!! And seems as though it agrees with my skin much better than the other high end brand. I will be purchasing again.
Vitamin C
This is an amazing serum. I am 69 years old and began seeing results within a week. Sun spots were disappearing. After applying to my face I would rub on my hands and now they look younger. Worth the price.
Great serum
I have never believed in vitamin C serums but I have been wrong 😊. Obagi C serum 20% is incredible. In 2 weeks of daily use my skin was softer and fine lines around eyes less visible. Love it and I will continue using it daily, and PM retinol.
A regular reorder item!
Obagi’s 20% vitamin c serum is the absolute best. When combined w other obagi products, like the face cleanser, toner, and 4% hydroquinone (Rx required) my face is smooth and radiant!
Melisco
Love this stuff! My dermatologist asked me what I was using on my skin because it’s the best She’s ever seen it. Definitely leaves a glow on your face.
Wow
I never thought I’d stray from the most popular C serum, but finally decided to try Obagi brand and I am beyond happy with my purchase! This is my new go to C serum!
My Skin Looks Great!
I started with a lower strength and really liked what it did so I moved up to a stronger strength. Love what is has done for my face. I also add it to the backs of my hands to fade age spots.
Love this!
Vitamin C serum a must! It really boosts skin to next level more than just a moisturizer can do - especially for dryer and aging skin! This is a quality brand and I love the 20% strength!
You need this in your life
Best product out there. Everyone needs to be using this especially if you are in your 40's (I am 47). I started out with the 10%, and then went straight to the 20%. and never looked back . My skin looks amazing and glows. This product evens out your skintone so you don't have to wear so much makeup! I wear Colorscience makeup. The smell takes some time getting used to but once you layer your moisturizer it's gone.
Obagi 20%
I have used 20% Obagi for years and love my results.! It has helped the overall appearance of my skin.
