This product evens out my skin tone and even cuts the oil. My skin looks great after 2 weeks. —Eric717, kiehls.com

Rated 5 out of 5 by from Absolutely amazing I rarely write reviews but I have never experienced such a difference with a beauty product. I didn't have too many skin issues to start with. I'd say my skin is "normal", although it can look dull and tired. I've also got some post pregnancy spots and uneven skintone. I've been using this for about two months and I'm thrilled with the results. My skin is even in tone, my pores are minimized, and I've got this incredible youthful glow!! I couldn't be happier! Highly recommend this product and I'm looking forward to using it for many years to come.

Rated 4 out of 5 by from Seems to work I replenished this after using a sample I felt was working for my deeper lines...it can sometimes feel greasy but if you get the amount right for your skin it’s smooth and works in nicely to your skin. Note: I decided to buy this because Kiehl’s kept pestering me to use my rewards points - which I know exist. But when I log in to my account I get a blank screen while looking for “my rewards”...and can not access this “expiring” coupon. Why?

Rated 5 out of 5 by from Love this one SO much I have normal skin without any particular problems. I just want something to keep my skin as nice as it is. This product did more then that. I saw visual improvement in my skin. My skin jot brighter and smoother. It felt weird the first time I applied it on the skin because it warms right away. You get used to it. One pump goes a long way. Would definitely recommend this.

Rated 5 out of 5 by from Amazing!! After using it for 12 days, yesterday, I received a comment from someone surprised by how good my skin looked! It's really amazing how effective it is. My question is: How long can it be used? After eight weeks of treatment, can you continue or is it advisable to rest for a while?

Rated 3 out of 5 by from Formula changed I bought my first bottle a few months ago. LOVED it. Within a couple days my face looked better. Moisturized, better texture. THEN I bought a 2nd bottle. The color was different (white, 1st bottle yellow) and it smelled different and felt different on my skin. Returned to store for exchange. Same thing with a new bottle. Just ordered 3rd bottle direct from Kiehl's so will see how this is. Very expensive but was willing to use as I loved results. Not so much anymore.

Rated 3 out of 5 by from No Improvement in fine lines I have fine lines in forehead. I use this serum after toner every morning. It’s been an year and not a bit of improvement in the fine lines. I am very disappointed that it’s working for many people and not for me.

Rated 2 out of 5 by from no visible effects I purchased this at the recommendation of a Kiehls employee who said I should consider it for help managing fine lines and large pores. I've used it with the other Kiehl's products in my normal regimen (ultra facial cleanser and ultra facial moisturizer for oily skin) for the last six weeks and have not seen any impact of using this product.

Rated 1 out of 5 by from Weird!!! I have to join the slew of bad reviews of this product. I bought this serum after receiving a sample. It seemed good but then I noticed my hands smelling really bad. It wouldn't wash off and it lasted for days. The smell was of metal. I went to the doctor. They ran tests and said it has to be something topical. I never in a million years thought it would be this serum. Once I discontinued the use my hands stopped smelling. I started again two weeks later and the smell returned. I know it sounds funny but as I was sitting in my office I could smell my hands and it was driving me nuts!

Rated 1 out of 5 by from Effective but ruined all of my clothes It is an effective serum and I would like to use this on my neck and during nighttime but I can't because it stained all of my clothes (esp shirts with collars) and my pillow cases. Most of the dry cleaners, except for one, were unable to get rid of the orange stain.

Rated 2 out of 5 by from Confused?!? I received this product as a sample and was in love so I decided to make purchase. This product does not seem the same. It continues to leave my hands stained and my hands and face in the morning smell like I have used a gradual tanner. Wish it was performing like it had when I sampled.

Rated 5 out of 5 by from Love this So far I love this product using it regularly I do see wrinkle line reducing slowly happening. Keep away from eyes.

Rated 1 out of 5 by from A dirty bottle with no manufacturer seal I purchase this online and when I received it, there is no manufacturer seal. The bottle is very dirty and it doesn't even seem to be a full bottle. I'm not trusting it. I can't exchange it in store and I need to pay the return shipping fee to return it even if it is not my fault. Worst shopping experience ever. Will never buy anything from Kiehls.com.

Rated 5 out of 5 by from Loyal Fan I have been using PSLRC for almost 8 years now in conjunction with many other Kiehl's products. Ever since I began using Kiehl's, my skin has become smoother, calmer and breakout free. I believe consistency in using the products and patience is the key. I never thought I would have "good" skin. In the past, my skin was very oily and prone to embarrassing breakouts. Now, women ask me who my facialist is! I just tell them "Kiehls". I even feel confident not wearing foundation on lazy days. Never thought that would happen. Love letting PSLRC soak in before my next step of oil. The only negative I can say is not the product but the packaging. When it gets to the bottom of the bottle, the pump is no longer effective. I then need to scrape out the remainder which is a substantial amount - enough for 2+ weeks worth.

Rated 1 out of 5 by from Warning - Stains Fabrics! Used this product for 3-4 weeks before realizing that it was the cause of mysterious orange stains on my pillow cases and shirt collars (that cannot be laundered out). I'm a big fan of many other Kiehl's products. But this one has ruined two sets of sheets and about a dozen dress shirts. Be warned...

Rated 5 out of 5 by from In love! I'm on my second bottle. My first bottle was last year and I fell in love with the texture and results. I'm in my early 40's. I don't have very visual wrinkles but I do like to take care of my skin before anything drastic happens. I love the way it left my skin after weeks of use. My skin did looked more youthful. The pours minimized and it toned my skin. My comments/question is and I would like a reply back on this, the texture on the first bottle was a little raspy. When gliding through my skin it felt like a scrub feel. I didn't mind it at all. It left my skin super smooth. But on this second bottle I just bought last week, the raspy texture is not there anymore. What changed? Will it affect the outcome of this product? My skin in normal, a little dry in the winter. The serum does not leave my face oily or shiny. It absorbs quickly. I do use a gentle scrub so maybe you should add that to your routine in order for this product to work the way it should. I love this product and I wish it was a bit less expensive but I will continue to use.

Rated 5 out of 5 by from Wonderful ! Totally in love with it ! This is the most lovely product that I have used ! I will use it for my whole life . I love the texture , the smell and the effects over all. It works great on my skin , left a good feeling on it . I use it 2 times a day and it absolutely has changed my skin , it's soft like a baby skin . The price is unconsidered with the effects . Definitely worth the price and definitely is the best product followed by Ultra Facial Cream . Thank you Kiehl's . I love all the products !

Rated 5 out of 5 by from Did you get botox!!! I used Too much of sample of this product. Its a bit deceiving as it looks like a cream but its consistency is more oily- going a long way. Because i used too much by how it came out, i waited to go to bed- not wanting to stain my pillow. At work the next day my coworker made me “ wrinkle my forehead “ to prove i hadnt received botox. The effects of this product were so good. I ordered it and am using it now. I still use it generously and let it sit for 1-2 hours before going to bed. I have dry skin& am in my 50’s and need it generously. Love the warming sensation when putting it on. It a ts like a mask that you dont wash off. It will be completely absorbed in the morning.

Rated 5 out of 5 by from Great face serum! Tried a sample and then switched to this from the Age Defender serum. Much more effective. Really kind of revealed the underlying and fresh skin. I’m apply twice a day followed by Facial Fuel over it. Only been using for a couple of weeks now but very impressed so far. Best Kiehls product that I’ve used to date.

Rated 1 out of 5 by from Nothing changed, waste of money. 30 days later I saw zero change. I’m so tired of false claims I took a pic before then again 30 days later. It does not work at all. Too pricey at any cost for zero results. what I’d love to see is a 55-60 year old model! I didn’t have even fine lines at 45 and you’re using someone who’s “almost” 40, this is a joke. I have pretty good skin but not even a change in the finest of lines. No thank you!

Rated 2 out of 5 by from Initial Thoughts I will have to wait a few weeks to see the long term results. However, it is quite hard to wear from first impressions. The citrus smell is quite strong and slow to dissipate. It leaves a shiny and silky residue when you first put it on that doesn't really disappear, which is quite annoying because it brings out the wrinkles and texture in your skin.

Rated 5 out of 5 by from Really impressed I really like this product and have been using this for many months now (on my 3rd bottle now I think?). I use it morning and night after cleansing. A little goes a long way (1-2 pumps). I find all products like this work best when you also regularly exfoliate which I do about 3 times a week. This product leaves my skin very smooth and has had a significant improvement impact on fine lines and wrinkles. I plan on continuing to use this for a long time. Thanks Kiehl’s!

Rated 2 out of 5 by from Bottle #2 Being a new custom to kiehl's i was very excited to try the products and really like some of the other products. I have to agree 100% with some of the other reviews on this line reducing concentrate changed..I was so impressed with my first bottle and saw such a difference in forehead lines reducing and now my second bottle not the same and is not working and now the lines seem to be returning

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.
