HERITAGE HIGHLIGHT

HERITAGE HIGHLIGHT

Kiehl’s chemists stabilized 10.5% Pure Vitamin C in a water-free formula more than 13 years ago and became pioneers in Vitamin C skincare products. Now, our formula includes 12.5% Vitamin C and Hyaluronic Acid.

Powerful-Strength Line-Reducing Concentrate is rated 4.6 out of 5 by 597.
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!
Date published: 2018-10-02
Rated 1 out of 5 by from Old formula was much better I wish you would bring back old formula, keep this one if you want, but give us the choice. I, like many other reviewers here, saw results with the old formula but not this one. The new texture is also sub par. The old texture was velvety and left a nice surface for make up. The new texture is sticky and thicker. I had just found the old formula and only had a sample size to enjoy and it was enough to see results. I went in to buy a bottle but it had been discontinued so I tried new formula. I've been using it for over two months and not even the slightest difference. Looks like my search for a good Vit C is back on :(

Rated 5 out of 5 by from Can't Live Without! I have been using this serum for a few years now, starting with the old formula (10% vitamin c) and then swtiching to the new formula (12.5% vitamin c) when it came out last summer. When i started using this product I was approaching my mid 20s and had problems with acne, the start of forehead wrinkles and a general dulling of my skin that was the result of many sleepless party nights in my teens and early 20s finally catching up with me. This product has drastically changed my skin and it has continued to improve over time. My skin is now smooth, plump and radiant. Any wrinkles I thought were starting to form are now long gone. I rarely ever breakout and have completely stopped using foundation. I am constantly getting compliments on how beautiful my skin looks, when little do they know just a few years ago my skin was a dull acne ridden disaster. This is my number one must have product that I can't live without. I use daily morning and night with the rosa aratica eye cream under either a day time moisturizer with spf or a night cream/kiehls ultra facial cream at night. The product may seem pricey but each bottle lasts a few months and the results are definitely worth it. Highly highly recommend!!

Rated 5 out of 5 by from Incredible results I have been an avid midnight serum user for many years, but recently got to try this out when I won a keihls bundle in a Facebook competition. Out of all the products I chose I cannot believe I only took one of these - it is incredible. I had a few weddings over summer so started using it about 2 weeks before. The results are flawless, bright and scar-free skin. My skin is glowing to the extent that people have been asking me what I’m doing. Coupled with a solid cleaning and prepping regime, this product is definitely one I’m going to buy when it runs out. Love, love, love it!

Rated 5 out of 5 by from Amazing Results I have been this daily for 6 months. I bought it to help reduce 2 frown lines between my eyebrows that were annoying me so much that I was considering getting botox! But not wishng to go down that road I decided to give this a try after seeing before & after photos. I cannot believe the difference this has made, firstly my 2 frown lines which were quite deep are now reduced to faint lines and the rest of my face feels plumped and smooth.

Rated 5 out of 5 by from My favorite! I started using this serum a little over two years ago–I've always loved it! I've been looking for other alternatives, though, but haven't had any luck. I like to try out different products just to see if I can find something more effective and/or that offers better value–but I always come back to this one. I love the texture and how it makes my skin feel and look after application!

Rated 2 out of 5 by from Bring Back the OLD Formula I have been a faithful user of this Serum for many years. When my old bottle (10% VitC ) ran out I went to my local Kiehls dispensary to restock. I felt the new 12% on my hand and it does feel nice.I went ahead and gave it a shot. Well after 6 weeks of 0 results. I finally returned it last night. Why did they reformulate? It was probably cheaper to make this one than the old version. But do not be fooled this new one has silicone way up on the ingredients list . I still have my old box so I noticed a significant change in the ingredients list from the prior formula. The only good thing I can say is it didn't break me out which usually happens when brands reformulate products on me. Do not waste your money. Kiehls is slowly becoming so much less special than it once was.

Rated 5 out of 5 by from The best so far I have always used kiehls products but this is a first trying anything for wrinkles/lines. I love this stuff! It took me weeks of deciding which Kiehls face product I wanted to try, reading reviews mostly. So glad I went with this one! Love the texture & the way it makes my skin feel. Saw results almost instantly & I have some pretty heavy lines in my forehead. I also got some really cool samples which is how I also pick what to purchase, the samples are smart because I always end up buying one of them. My lip balm tube was pretty much empty though which is really weird, couldn’t squeeze anything out.

Rated 5 out of 5 by from Worth it I read some of the negative reviews and realize we are all different; ages, ethnic, life style, etc.....but this serum works for this former beach bum who is now in her 6o’s. Love it and will use it for years to come.

Rated 3 out of 5 by from absort fast but donot see line has been reduced or skin texture has been improved I have to say this product is absorbed fast by my skin but does not see wrinkle or line has been reduced or skin texture has been improved..kind of expensive for the price itself.
Date published: 2018-07-17
Rated 5 out of 5 by from Amazing I bought this almost two weeks ago and I’ve used it daily in combination with the midnight recovery and my skin has never looked better, it’s glowing. I’m still quite young so I don’t really have much in the way of wrinkles but I have noticed that the small crease I noticed forming on my forehead is nonexistent now. I would definitely recommend trying it.
Date published: 2018-07-17
Rated 2 out of 5 by from I have used this product faithfully, twice a day, for the past 4.5 weeks and I have yet to experience any of the positive effects described here. On the bright side, it doesn't seem to clog my pores which surprising since I just found out this product has a pretty high silicone content. It does make my skin appear dewy after applying but that doesn't last very long. After nearly 5 weeks, I would have liked to see some improvement in my lines and texture but, unfortunately, I have not. I also think this smells like DHA (the stuff that makes sunless tanners stink). Not very thrilled with spending this much money on something that doesn't do what it claims to do.

Rated 1 out of 5 by from Questioning Sterility I've tried almost all Kiehl's products available. Many helped to enhance my skin texture and appearance, and I always recommended them to my friends and family. This one in particular though, didn't really work well with my skin. However, when I tried a sample of the updated one, I had to get it! I ordered a full size online. When I opened the box, I saw a thick stain of eyeshadow on my bottle. There was even fingerprint stains all over it. I'm afraid Kiehl's recycle their used content? I feel uncertain about using it now...
Date published: 2018-07-04
Rated 3 out of 5 by from Stinging feeling I requested a sample but found is was stinging my face.Therefore I feel if you have sensitive skin may not be ideal as Im sure it wasn't supposed to have that effect.

Rated 1 out of 5 by from Had High Hopes Been using this serum morning and night for over two months now. I have fine lines on my forehead that just bother me and it was recommend by a Kiehls specialist that I try this stuff. I was super optimistic and tried to be patient as I waited for the lines on my forehead to soften. After using both in the morning and night for 1 month, I decided that maybe I needed to give it another month to experience the transformation. Unfortunately I’m now over two months in and have yet to experience any changes to my creases and have actually started to see more creases appearing. Also the serum stains my pillow case. It washes out but it doesn’t look pretty in the meantime. Was super excited about this product but the results were very disappointing.
Date published: 2018-06-28
Rated 5 out of 5 by from Wowww Living in Florida, I became more concerned about the creases developing across my forehead. I’m in my early thirties and tried multiple pricey products. I put it on my forehead at night and the difference is noticeaable. I’ve been using every night for two weeks and the creases continue to fade. The cream is light weight and blends in immediately. No greasy feeling, absorbs immediately. Almost feels silky when blended in

Rated 4 out of 5 by from Not quite right I have to say I really liked the product, but it's difficult for me to give it 5 stars. I cannot believe reading all the reviews that nobody has mentioned staining on the bed linen, especially pillows. It was so bad that unless I literally changed my bed every day I had to avoid using it at night which is probably when I really want to use it. The staining on my palms was equally disappointing. I'm just really baffled that nobody else has commented on this. It is a shame as I really did like the product.
Date published: 2018-06-22
Rated 5 out of 5 by from Buy it. This product turned out to be such a surprise for me. The work it does from first application of plumping even deep wrinkles, just knocked me out of my chair. I've only had it about a week so I can't speak to long time result. But even if it doesn't do another thing what it does immediately makes it worth every penny. If you're over 50 you can't afford to be without it. I understand people who don't like a lot of steps but this is the best line filler I have ever tried.

Rated 5 out of 5 by from The Best Vitamin C Serum!! Soft to the touch on the first contact with my skin! Instant boost of hydration. Smooths my skin out and freshens it. Don't let it hesitate you when it claims only to help wrinkle problems. I'm 21 and acne-prone skin with some acne spots. I bought it because I was looking for some good Vitamin C to help brighten the spots. This serum doesn't only excel at my need, it also smooths my skin out and gives it a boost of energy. Big plus, this Vitamin C serum doesn't break my skin out or clog the pores like tons of other Vitamin C serums I've tried. In fact, I feel like this serum helps other products I put on afterwards absorb faster. Will be repurchasing!!

Rated 4 out of 5 by from okay This product smells good, but it tingles my skin a litter bit. Speaking of effect, it does not show very obvious effect but there may be several influences. Btw I do not have much lines. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great Product I needed a product to improve my skin texture and reduce the appearance of my wrinkles. A store associate recommended that I try this serum and it was a great recommendation. After using the serum once a day I started getting compliments on my skin without makeup. I've been using the serum twice a day for a month and I am pleased with the results. I prefer not to wear makeup and this product has helped me love my natural skin again.
Date published: 2018-05-20
Rated 1 out of 5 by from So disappointed! I bought this after reading the great reviews and it’s pretty much ruined my skin. The product has a nice smell and texture, but it’s way too oily leaving my skin really bumpy and spotty, I assumed it needed a “purge” period, but nearly a month down the line and my sensitive/combo skin is an absolute mess!
Date published: 2018-05-12
Rated 2 out of 5 by from Not worth the money spent This is my first time using a Kiehl's facial product but longtime lotion fan and I was super excited when I read the reviews about this serum. This product was on the pricey side for me but I decided I would give it a try. When you apply it the texture is wonderful and a tingling on your skin does happen, in a good way and makes you think something is happening ........but it doesn't and has not happened yet. I have been using it for almost a month now and disappointed because i had high hopes. Its's too bad becuase Kiehl's is a great product they just didn't deliver the results they said it would in this bottle.
Date published: 2018-05-10
Rated 5 out of 5 by from Love this! I have been using this product daily (sometimes twice a day) for about a month now, and while I haven't seen a significant change in fine lines and wrinkles, I have noticed a dramatic change in the brightness of my skin. I have less discoloration and a subtle glow. I am hoping with more use I will see more improvements with wrinkles, but I am very pleased.
Date published: 2018-05-08
Rated 3 out of 5 by from Shame on Kiehl's for putting such a great product in cheap packaging I love this product, and have used it for years. The new formula is much better than the old one, which is not something you can often say about reformulated products. My only gripe with this is the packaging. Unfortunately, it's a cheap plastic bottle with a pump. For the money, one would expect a higher grade of packaging, and in this day and age not to use a more sustainable glass bottle is irresponsible. The pump, while convenient and designed to minimize air flow in the product, isn't air tight and allows the unstable ingredients like vitamin C to get exposed to air which can reduce its effectiveness. Do yourself a favor and buy the smaller package so that you stand a better chance using up the product for air exposure makes it lose its effectiveness.

Rated 5 out of 5 by from Amazing! I received the Powerful-Strength Line-Reducing Concentrate as a 4 pack sample. I’m 42 years old and have desperately been trying to find a product that works for repairing my uneven skin tone and reducing lines, wrinkles and dark spots. The first thing I noticed was how warm and smooth it felt when applying it. A little bit really went a long way, so I was able to use 1 packet for two days, because I only applied at night after I showered. Within a few days, I could already tell it was helping to fade my red spots from healing acne, which normally takes more than a week to disappear on their own. In only 8 nights of use, my skin looked and felt more youthful & radiant and the fine lines around my eyes and mouth seemed to be less noticeable. I was sad to have ran out of the product samples, but I definitely plan on ordering soon!

I do not use this on neck or chest. It won't hurt to use it, but you may not see the results you are looking for. See if Kiehls has neck/chest treatment. The neck and chest requires different treatment than face in my opinion.

Do you use this serum in conjunction with the midnight recovery serum. And if so which one goes on first?

Asked by: Grier
While I use the Midnight recovery every night, I put on the line-reducing concentrate every other night. Just a personal preference and it's all up to you to use them together every night. And I usually put on the line-reducing first, then leave the oil on after. I think it works better that way as the midnight oil can get sticky and it's hard to apply another layer on top.
