Skinceuticals Serum 20 AOX+, 1-Ounce Bottle

This 20% Vitamin C serum with ferulic acid is very effective at keeping my skin youthful looking. This is the only skin care product that I regularly use. I started using it about 12 months ago and am very happy with the results. It is expensive, but when you consider that it only takes 3-4 drops to cover your face, one bottle goes a long way (for me, a bottle lasts 5-6 months of once a day use). I'm a firm believer in antioxidants anyway, eat lots of healthy food, take supplements and exercise, so the fact that I look great for my age is not just the skin care serum, but it does contribute. One thing you should know is that because it is an acid, it tingles a bit when you apply it, and it dries your skin a little because it causes a subtle and gentle chemical peel. The drying is not an issue for me, but it might be for someone who suffers with dry skin. Also, I hesitated to order on Amazon rather than at my salon, but I received exactly the same bottle that my salon sold me for almost $50 more.

I love the product but, sadly, didn't get much time with the product before accidentally knocking over the bottle and watching it break all over my bathroom floor. After spending over $80 for this, my heart sank when I saw the shattered glass. I reordered but opted for the smaller trial size bottles which cost considerably less anyway.The product works as advertised and makes my skin tingle a bit when applying (not in a bad way though). I've only been using it for a few weeks but saw results very quickly (brighter, smoother skin). I wish it had a bit more viscosity (thickness) so it didn't drip down my face as much before I get to rub it in. I'm a big fan and, as mentioned previously, I bought a replacement after breaking the bottle of my first batch.

My spouse has been using this product after a removal of a basal cell carcinoma on her face. Her surgeon recommended the product. The product has worked exceptionally well. If you have this type of issue this product is truly excellent The vendor has also been very good to work with.

This is too harsh for my skin. I have been too busy taking care of my mom and wasn't able to return the item in the time frame it stated. All 3 of the skinceutical products I ordered are way too harsh for my skin.

I have used this product for over 2 years and have always purchased from SkinCeuticals. When purchased from the makers of the product, the serum is light, thin and not gummy. As soon as I opened the bottle, I knew it was old. Over time the serum will darken,however even after 3 mo of having an open product it has NEVER been this dark. The product this company is selling is very old. It arrived in original packaging and sealed. When taking the dropper out the serum was orange and sticky. It is mostly not as effective. I will never buy from here again. I encourage and recommend this product. You will see incredible results to prior environmental damage. It is a great product!! ONLY WHEN PURCHASED FROM THE MANUFACTURE!!

I have been using Skinceuticals Serum 20 and B5 gel for many years, but I have previously bought it from my doctor. I have frequently gotten compliments about my skin. As a recipient of Social Security, I am very pleased by the number of people who are surprised by my age.

I've always loved this serum. I was so happy to find it on Amazon at a good price. If you want a serum that penetrates down into the layers of skn, and undoes the sun-worshippers damage, this is it! I use it on my décolletage as well. Worth every penny.

Love this!! I used this a couple years ago, and am glad I found it again. It brightens my skin, and has helped my dark spots to be less noticeable. I do not use the full 5 drops, so it lasts a tad longer, but I still notice he benefits.

Excellent quality and fast delivery. not a fake

On time and nice product
