20% Vitamin C Night Repair Serum (0.5 ounce) - Vitamin C Serum for Dry Skin with Alpha Lipoic Acid, Hyaluronic Acid, DMAE, and Green Tea EGCG

I'm on my 3rd bottle. A 1/2 pipette goes along way. Use product before moisturizer

I have only been using this product for about a week, so it is too soon to see any results. But, I did want to review what my general impression is ofKate Ryan products. I am a big researcher. I really like to study ingredients and understand what they do. When I decided that I wanted to start treating the creepiness around my eyes, I began my homework. I read many, many labels of all brands of eye products. Most of them were very pricey and well known. I just figured that these would be better. After a getting a bit of understanding on the specific ingredients, I knew better what I needed for my eyes and face. I was just about ready to give up because even the well known pricey products did not get as good reviews as I wanted to see and they did not contain the specific ingredients that I wanted for myself. I accidentally stumbled across Kate's line. What I like about her products are: I got immediate delivery. That tells me she really is on top of her game and wants to please. Her products are manufacture in the USA. I also appreciated her prices. They were reasonable. I could afford them and I didn't wince like I would have if I had gotten some other brand. The ingredients in the two products that I purchased were exactly what I was looking for. This first order, I got the vitamin c night repair serum and dmae serum. My only complaint is the pump bottle that the dmae comes in. I don't like that. Too much squirts out, it is not controllable with the pump. So, I unscrew it and just dab the end of the pump tube onto the tip of my finer. I will most likely purchase from her again.

I came to the age when the wrinkles want sneakily start invading my face. I need to have a good defense against that! I tried many things and found that 20-25 percent vatimin C is one of the best fighters. Before I found this serum i used to make my own solution but that was painful (getting stuff, measuring, making it fresh every few days). Then I found this serum. Thank God,! Works very well and lasts long time without C going ‘bad’. I am on my second bottle and planning on buying it over and over. I also use good high concentration retinol serum and these two together are the best defense against wrinkles! A week ago I had diner with a group of people that I haven’t seen for over a year and they told me that I am aging backwards. The best justification for the product. Also I would like to mention that the service, packaging, attention to the details, and shipping speed are outstanding.

It seemed to work for about one month, I did notice a brighter complexion and undereye circles lightened up, it does go on oilier than I prefer and caused breakouts on my forehead although I do have combination or T zone type skin. But I believe that because of the bottling of this formula or the quality of dropper used I noticed an oxidation of the formula because my skin no longer had the glow I was seeing, it just stopped working after the second month. The rubber top on the dropper began to give off a bad rubbery odor and black substance was coming off like the rubber melted into the formula! The rubbery odor infused the entire formula and I had no choice but to throw it out. it was a waste...

Love this serum! I've always used a vitamin C serum with ferric acid and phloretin during the day (I've just used up my bottle of that Skinceuticals product and now will use the Kate Ryan C serum for day starting in the Spring), but wanted something more hydrating for my dry skin in the fall and winter. This is perfect not just for night time but I love it during the day underneath my sunscreen and BB cream. It's not too oily as it sinks in beautifully and gives my skin a subtle glow. It's also wonderful to know that it is protecting my skin from free radicals caused by sun, pollution, etc. I will not be without this product!

Fantastic Vit. C!! I got a wicked burn scar on my nose a few years ago. I tried prescription scar treatments, cosmetic surgeon treatments, and a landfill of ineffective products. Nothing helped. I purchased the KR Vit. C Nightime Serum, and it's done more to eliminate the scars than anything I've tried - and that's about everything! I've been VERY happy with all the Kate Ryan products, and customer service is absolutely unparalleled! LOVE IT!! Give it a go! You won't regret it!

It’s a good product but needs to come in roll on like the sample. Hard to get it applied evenly because it soaks in too fast Loved the sample product. Disappointed that I placed a larger order over 100.00 with no samples sent this time. I really liked the roll on sample of this product.

This Product was recommended to me by my aunt. She is 45 but looks about 28 so needless to say I gladly took her advice ;). And I love it so much!!! I have exceptionally temperamental skin ( irritation, easily clogged pores ) but not only does this product feel good on my skin, every morning my skin looks great! Moisturized, small pores, dewy and pleasantly plump. I highly recommend it as a nighttime moisturizer that is light and refreshing.
