I have used this product for 5-6 years. It was recommended to me by a dermatologist. I will not go without it. Drugstore.com has the best deal. It seems to be more expensive at physician's office.

Having use The Serum 15 for over a year with great results, I thought I would try this as I had heard fab reviews. Im late 30s very few lines and not a sensitive skin type. After about a week of using this my skin became incredibly dry felt sunburnt and totally irritated, I really cannot reccomend this product as my skin looks worse than ever and I cant use anything apart from Hydrating B5 at the moment as Im so sensitized by this so called wonder product!!!

noticeable results after about a week of daily use. A little odd to use-a dropper to dispense- I use four drops a day. Totally evened out my skin tone and smoothed fine lines! This will be a product I use forever!

Here is the story with the red bumps some people complain about: I get these a day or two before my monthly facial at the derm's office. I think if you are getting these, you are in need of exfoliation, deep cleaning, etc. Otherwise the red bumps do not happen. I love this product, it has helped my melasma and makes my skin clear, smooth, protected and lovely. Been using it for about a year. use with other skinceutical products for best results.

I bought this due to the overwelming good reviews; however, I did not find this product helpful at all. I am in my mid-30s and have fine lines. My skin got dried out and looked more aged after a month of using this product. I am very disappointed. I switched to a different product and my skin started improving - at least back to where I started. It's a nightmare to buy something to help stop aging skin, only to have it accelerate it. I would not recommend this to anyone with a normal to dry skin type.

I use it everyday I love the way it makes my skin look and feel

I'M 43 YRS OLD - HAVE BEEN USING SKINCEUTICAL SINCE I WAS APPROX 36 YRS OLD - HAVE TRIED ALL THE EXPENSIVE BRANDS.. THIS IS THE ONLY PRODUCT LINE THAT IS TRULY WORTH IT. I WAS INTRODUCED TO THIS PRODUCT BY A LICENSED ESTHESTICIAN - YOU TRULY GET RESULTS WITH THIS PRODUCT.. I LOOK MUCH YOUNGER THAN MY STATED AGE - AM TOLD THIS BY MANY - HAVE TRIED OTHER PRODUCTS TO SEE IF THEY WORKED OUT OF CURIOSITY, NEVER EVER CAN THEY COMPARE - THIS PRODUCT IS WORTH THE $$ - REALLY!!

Highly recommended by dermatologists, this is a top quality vitamin C facial serum. With the addition of Feurulic, this serum helps to better protect the skin from sun damage.

I use the product on the recommendation of my skin specialist. It has made a difference in just three months. I use it on my face, throat, decollate, and the backs of my hands and wrists every morning. Yes, it goes faster this way but a little bit goes a long way. I have noticed a decrease in wrinkles overall and a definite decrease in the depths of the deeper wrinkles. There is a definite odor to it, but it dissipates quickly and is not noticable by the time I put my facial lotion on over it. Overall, I highly recommend this product.

Absorbs into skin quickly , feels great. Pricy but haven't found anything comparably effective. Lasts about 3-4 months.
