Rated 4 out of 5 by from WOW It really works I tried some at an Ulta beauty shop and couldn’t believe within a couple minutes the lines under my eyes and forehead were 75% gone. I’ve tried many products and nothing has ever worked like this to get rid of wrinkles instantly. As far as the consistency I found it a little greasy but I would put up with that especially like the price value. My only complaint is the second ingredient is dimethicone and according to things I have read it puts a coating over your skin not allowing it to breathe. Why does Kiehls use this and not more natural ingredients in their products? I will stick with Anthony products because of the reason above. Otherwise I would’ve switched. I may decide to use it during the day and Anthony at night

Rated 1 out of 5 by from Not up to expectactions I was really looking forward to this product after reading so much good reviews. I've been using it for two days -- so I cannot comment at all on the long term effect of the product. There was no immediate effect. The feeling after putting the serum on my face is just bad. It feels like a thick coating layer that doesn't soak in, my skin doesn't feel like my skin but with something on top that is sticky, strong and as if it doesnt let my skin breath. I just have an urge to wash it out. I dont know if it is the silicone which is super high in the ingredient list, or another ingredient, but its not comfortable and I dont think I will continue using it, but search for another vitamin C based serum. Sorry :(

Rated 5 out of 5 by from Life Changing!!! I developed fine lines on my forehead early (around 19-20 yrs old), probably due to my face expressions/drinking a lot in college. I was very insecure about them. About 1.5 years ago, I bought this line-reducing concentrate after much research. The concentrate worked wonders!!! and the bottle lasted awhile. I will now only see faint forehead lines if I'm super dehydrated while talking a lot. (weird observation but I'm very self-aware!)

Rated 5 out of 5 by from Love this I am a 43 year old male with oily skin. This product evens out my skin tone and even cuts the oil. My skin looks great after 2 weeks. I will keep using. I use it twice a day after clensing, then toning, this product, then when it dries a moisturizer.

Rated 5 out of 5 by from Love this product! Using my second bottle now. Continued use has definitely reduced my wrinkles and plumped the skin. I'm about a year out from quitting smoking and this has really helped bring my skin back. It does work better to use alone as the only serum under moisturizer, I find. If I add a second they can pill.

Rated 2 out of 5 by from Fourth bottle now - prefer the old formula I loved the velvety texture from the old formula, and I genuinely felt it made an impact on my fine lines. I am now in my early thirties and need more than just moisturizing, and this serum was what kept bringing me back to Kiehl’s. This new formula, as others have mentioned, feels sticky upon application and does not seem to affect my fine lines whatsoever. I have finished the large size of the new formula, and I am unimpressed and can’t say I will be purchasing another bottle.

Rated 5 out of 5 by from Amazing! I’m hooked Got this in a sample form & once I tried it I knew I needed to have it in my life. It goes on a little oily but dries down to perfection, I feel younger after using this and I’ll be back for more! Thank you Kiehls for this magic product <3

Rated 2 out of 5 by from Less effective I've been using this Kiehl's formula for more than 5 years. It has always worked well but lately the product seems to turn orange quickly. I have really liked this product in the past but I'm concerned that it may not last as long or be as effective as before (i.e. thus the orange tint). Did the formula change result in decreased product longevity? Please fix it as I really value this product.

Rated 1 out of 5 by from Please bring back old formula Just purchased a new bottle after absolutely loving what this product has done for my skin however the formula has been changed and this is not at all the same product as before. I appreciate that you have increased the percentage of of vitamin c however that is not the game changer here. The old formula went on smooth and blended well into the skin without being oily. It had a slightly yellow color at first glance and seemed to be slightly tinted when applying to skin which was great. This also helped to enhance the “blurring” effect over fine lines which in my opinion was the primary reason I fel in love with the product. An unspecified sum of money later, the new formula is white/not tinted, leaves skin looking and feeling noticeably oily, and I hate to say feels as if I smeared generic body lotion on my face. There is absolutely no blur effect as before and the only noticeable difference after applying is that I look sweaty or greasy. I am sorry to leave a negative review however this is absolutely the one and only product that has made me a repeat customer. Unfortunately if the old formula is not brought back then I will sadly be on the hunt for an alternative. Sadly I do not think I will ever find a product equal in immediate visible benefits as your old formula. See photo for comparison of new formula v old formula.

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 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 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.

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 Excellent I really love this product! It has an inmediet brightning effect. Great to use in the morning and look fresh and with a healthy skin. Its a pitty its so expensive!

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 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.

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.
Date published: 2018-12-06
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!

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!! :-)))
