Rated 5 out of 5 by from Results in a couple of days blown away ! Coming from someone who's tries and tests every new product and i always end up disappointed.. but this is a miracle in a bottle. My face is smoother brighter skin just looks so much better x

Rated 5 out of 5 by from dull skin is better I have just used the product for a few days but I get a good result. My face skin looks better. Like it! In addition, I really like an eye cream as one of the product sample that I got.

Rated 1 out of 5 by from It just doesn’t work at all I bought this from Malaysia airport duty free shop . It’s feels warm in start when you apply but it is not giving any result I am 34 there are fine lines appearing on my forehead and under the eye too. I was hoping that it will work on my fine lines but it’s sad to say it didn’t work a bit .

Rated 2 out of 5 by from way too expensive for little results I do not normally leave negative feedback but after spending a lot for a product I expect it to work.I have been using this product for over 3 months now and have not noticed any difference.

Rated 2 out of 5 by from Can’t Notice Any Line Reducing Effect This product feels wonderfully warm when it goes on and like it should be doing something marvelous. Unfortunately, I have not noticed any line reducing impact after using over half the bottle, so I can’t recommend it, especially at such an expensive price. In short, it feels lovely but appeared to have no noticeable effect.

Rated 5 out of 5 by from Get the glow! I bought this product a few weeks ago now and am so pleased with the results. My skin is noticeably plumper and rejuvenated with minimal wrinkles. I love the warmth as you put it on your skin, it feels like it’s actually doing something! I tend to use it during the day as I use the night oil in the evening. Another product I highly recommend!

Rated 5 out of 5 by from excellent serum I got this as a sample because we are going on vacation and i was spending more time in the sun. I absolutely love the way my skin feels with just a little more the a pea size amount. it's warming when it goes on and soft. I already ordered more of it.

Rated 1 out of 5 by from Very disappointing I am a big lover of Kiehl's products and I so wanted to love this product as I do my other Kiehl's products but, after two months of consistent use, I have not notice any difference at all. Currently, I am 27 years old and am starting to have a few smile lines. I figured if this was able to be so helpful for older winkles, it should be able to help "fresher" wrinkles more easily but this has not been the case for me. My wrinkles are just as prominent as they were before starting this treatment. I will definitely be searching a new vitamin C product.
Date published: 2019-03-04
Rated 5 out of 5 by from I LOVE the way it feels I love this stuff. I have used the product for a month(?) and have no idea if it is visibly making a difference or not, but I know both vitamin C and hyaluronic acid are really good for my skin. And it feels so good!!! My skin feels so smooth. I do use moisturizer on top of it, plus a hydrating spray. I'm 66 and I need all the moisture I can get. My plan is to buy a bottle for my daughter on her birthday. She's turning 40 this year and we share a lot of skin products with each other.

Rated 1 out of 5 by from Has a warming effect This serum has a warming effect upon application. I applied it daily in the morning and every other night when I didn't use the spot corrector. Used for 6 months, but it didnt really even out my skin tone or brighten my face.

Rated 5 out of 5 by from Very pleased come thru vitamin C! I received a sample of this and tried it. I love the smell and texture of this product. It absorbs very easily into the skin and just smooths out all over your face. The product is a bit pricey! but beauty comes with a price! lol

Rated 1 out of 5 by from Didn’t Work It made no difference to my wrinkles or my dry skin at all. I’m really disappointed after paying such a large sum of money for this product.
Date published: 2019-02-02
Rated 2 out of 5 by from Not working for me I don't get it! I bought the smallest size and have been using it every morning for nearly 4 weeks and I see no effect at all. It's reasonably hydrating so I haven't had to use another moisturizer in the morning but that's it. No reduction in fine lines (I'm 33 and have noticeable fine lines and some deeper worry lines), no difference in tone or texture, no difference for sun spots or light acne scarring. I personally really don't care for the slick silicone texture - it doesn't really absorb, and just sits there feeling silicone-y. I haven't had any irritation or breakouts so it's not having a negative effect, but for the price I am disappointed that I have seen zero improvement.

Rated 3 out of 5 by from Unhappy with customer service I bought this product in Siam Paragon,Thailand. This is my first vitamin c serum. When I opened the bottle at my home, the serum was light yellow. However, since I do not live in the city, I did not go for an exchange. After two months, I did not see much difference so I decided to use a second bottle.I went to Central World, Chidlom and the serum was dark yellow. When I asked the salesperson to give me new ones, he said yellow serums are ok. The batch of serums he had was from August 2017. However, I asked him if I could see the color of other serums he had if he did not have new batch. He told me that I would have to buy it if he showed me. I told him I would not buy if it was yellow. He finally agreed and the serum was yellow and I said I would not buy it as I was given a yellow serum earlier as well and I was not happy about its performance. Finally he said he had one last serum left which was newer. This one was manufactured in Feb 2018 and the serum was white. I hope this time I will see some good results.

Rated 5 out of 5 by from Tried a Sample - Now Love It!! I have sensitive skin so I'm reluctant to try new skin products. However, this has been wonderful to my skin. Since I started using it I get numerous comments on how smooth my skin looks! Keep in mind to use as directed to get the full benefits. I was using it intermittently and when I used it as directed that's when I saw an immediate change and received (and continue to receive) nice comments about my skin :)

Rated 5 out of 5 by from Fine Lines Gone I’m a 54 year old male and I have to say that this product really gets rid of the fine wrinkle lines with regular use. It goes on matte which I like. Highly recommend if you want to dial back the clock to about 7 years or more.
Date published: 2019-01-19
Rated 5 out of 5 by from Dark spots GONE!! I have oily/ Acne prone skin and this product is the best I've ever used. As a Licensed Master Esthetian, I would recommend this product to anyone having dark spots issues. Been using this since early 2018 and I'm still in love with the results I've seen in just 1 week! Just remember to apply moisturizer (according to your skin type) after apply this product, morning and night. Lastly, always apply SPF 30+ or higher (Mineral/ Physical SPF is best). As for apply this products, a little the size of a pea is enough to cover the entire face.

Rated 4 out of 5 by from Felt the change The first time I used this product I was so happy with it, I suggested it to all my 30+ friends complaining about their skin and bought it as gifts! Now on my third bottle, I am not getting the same benefits I'd felt before. Is this because we've reached a limit as to what can be fixed? Or has Kiehl's changed the formula as suggested by other reviews I've read in astonishment here. My ratings are a bit mixed precisely because of this, I would have rated 5 hearts on all but value (I always feel these products could be a little more affordable). Now, however, I'm not happy with the texture at all -- it's less smooth and more greasy, the performance is dwindling and the effects are not as visibly felt as before.
Date published: 2018-12-19
Rated 3 out of 5 by from It's okay... I have sensitive skin, didn't get a reaction to this product. I feel like this dries way to quick when you put it on your skin. I have been using it for a month, haven't really noticed a difference. Not sure that I would order this again. I'm kind of disappointed.
Date published: 2018-12-19
Rated 1 out of 5 by from Not the same formula I've ordered this product 3 times now. I love it that much! But my last bottle did not performance as good as my other bottles I've purchased in the past, which was about 4-5 years ago. I had a feeling they might've changed their formula and after reading other people's reviews, my suspicions were confirmed true. I would like to purchase again but only if they go back to their old formula.

Rated 5 out of 5 by from Love this product I absolutely love this product. I have been using it for 3 months now. I love what it does to my skin. Less lines and a much brighter complexion. I have had lots of compliments on how great my skin looks, I even go to work with no make up on now. I am still going on the same 50ml bottle. This product will definitely be staying firmly put in my skincare routine for many years to come

Rated 5 out of 5 by from this product changed my skin I highly recommend it because I use it for 1 month and I have already realized important improvements in my face. My skin looks more bright and soft.
Date published: 2018-11-12
Rated 1 out of 5 by from Please bring back the old formula! While this new version is effective, the texture is harsh and grainy. It smells awful and tastes terrible. Since it is used for deep lines, like those often found near nose and mouth, aesthetics matter! Please bring back the old formula!
Date published: 2018-10-30
Rated 5 out of 5 by from My all time favorite serum in the world :-) I've been using this serum for many months now and I am in love with it. Generally, I take care of my skin very well but ever since I started using this particular serum, I noticed considerable changes on my face. It makes my face hydrated and at times I notice a glow. Love the texture and smell. Definitely erased fine lines on my forehead and around my lips after a continuous use of this serum. Kudos Kiehls!! :-)))
Date published: 2018-10-03
Rated 1 out of 5 by from Old formula was amazing - new one does not work!! The old formula had a very visible and stunning effect on mine and many others' skin. However, the new formula does not work at all. It doesn't even have the tell-tale 'warming sensation' of the old formula! Something's not right with this new one. This one with the hyaluronic acid is slightly more moisturizing, but the radiance effects and the line reducer does not work. I compared and found the last package of the old formula and it works wonder. This new one is horrible! Please give us a choice of the two, maybe one more moisturizing this new one, or the previous one. We want the old one back!! Will have to go searching for a new product as this one simply doesn't work since you changed it. Now can no longer trust this company to keep the good products around. I have 2 friends that also purchased within weeks of my purchase and they also had no choice but to use this one since they couldn't find the old one anymore, but they too noticed ZERO difference on their skin. This was my holy grail go-to product and now I can't use.

Rated 5 out of 5 by from Best skin care ever Ive got a very dry and sensitive skin. After using midnight recovery concentrate for years, i decided to try this product. It makes my skin hydrate, smooth and brighten just after a week using it. Best skin care ive ever used, highly recommended!

Can you please advice me when you go back to original formula?

Your original was top notch. I would see almost immediate results,which was amazing. I do not know why companies always have to mess up a good thing. With the negative comments I have been reading & hearing lately, I will not be purchasing any time soon. You lost here a long time customer.
Asked by: imqt

Serum texture

Just wondering what I am supposed to expect as far as the texture of this serum. I just got this one in the tube and have been using it for about 4 nights. Every time I apply it, the texture has a slight grittiness to it. I am just not used to serums having any texture other than silky. If this serum truly does has a slight grit or exfoliating property then I really just wanted to make sure I don’t have a defective product.
