Most Helpful Positive Review Finally...Something that does what it says!!
I received the Line reducing concentrate as a gift and I must say, its one of my most treasured beauty products. After the first few days the tone and texture of my skin had a noticeable improvement. I have some discoloration on my forehead, right at the hairline, from sun worship that has faded dramatically. I am extremely pleased with this product and I will never give it up.
A couple complaints I have heard on this product page are that the price is way to high and that it doesn't moisturize well enough. Let me start by saying that nowhere in the product description does it say that this product is a moisturizer. As a matter of fact if the label/directions had been read it distinctly states to wear it under you normal moisturizer.
As far as price goes, it is not cheap when you first go to make the purchase, but the fact that you will have this bottle in your skin care bag for 2 - 3 months (some may have it longer) makes this product no more expensive than some drug store brand you pick up one a month at your local drug store; of which rarely works so you end up actually wasting money on those products in the long run.
I would rather spend $60 on a product that lasts 2-3 months (or longer) that $10-20 one a month on a product that doesn't work nearly as well. Kiehls is a well established leader in the skin care community with a proven rack record. This is a wonderful product that I personally love (btw, my skin has been trouble since I was 9, so I have tons of skincare product experience) and I won;t have a problem dishing out $60 wen the time comes.
Thank You Kiehls!!!!
Most Helpful Critical Review BEWARE OF THE NEW 3.4 OZ SIZE BOTTLE
I am a devoted fan of this serum. It has saved my skin! I recently stopped into my local Kiehl's for yet another bottle and the salesperson immediately directed me to their new 3.4 oz bottle (for $100). I was delighted at the thought of more product for less dough! HOWEVER, I got it home and after plenty of shaking etc (and I'm REALLY familiar with this product), no matter what I did, this serum went on differently. It's almost chalky, not the usual light oily texture that soaks in nicely. It dries strangely and sometimes it even clumps, so I wind up with white smears all over my face! It's not the least bit moisturizing, either. In fact, it almost leaves my skin dry and less elastic. And it's funny, after selling me this, the salesperson said I really need to try their "new moisturizer to go along with it" and he handed me a couple of samples! Hmmmmmmmmmm......So, I'm guessing that the formula has changed and now they are trying to hawk another product to go along with it!?!? If that's the case, then Kiehl's please give me the good stuff or you've lost a very devoted and previously happy customer! I truly hope I just got a bad batch! I would love to know what Kiehl's has to say about this and I hope they address my review! Thanks!

I get a billion samples with orders, and this vitamin c packet was one of them. I slathered it on one night instead of my usual (The Ordinary's Ascorbic Acid 8% + Alpha Arbutin 2%). Noted it's creamy texture - instead of greasy - and layered my usual La Mer cream on top. The next morning I faced the bathroom mirror, and said "Whooooa!!!!" Very few products give me a double-take. My skin was plump with hydration, glowing and smooth. I bought a bottle of this miracle immediately. Now I just use in the morning with a summertime lotion (Belif's Aqua Bomb) on top, since I read that vitamin C products should be used as morning protectors against the elements of the day.

I like the facial effect of this serum, and a small amount goes a long way. I have very sensitive skin and found this to be too strong for use on my neck. I developed a burn-like rash after trying it on my neck. No problem using it on just my face.
Not a miracle
AdaC from OC, CA
I purchased this product during a 40% off sale. I was so excited. The ratings and reviews had been glowing on this product. I received it on 05/15/20 and began to use it immediately. I've been using it every night since, for a little over 6 weeks now. I have not noticed a difference in my skin. There is a nice chart in the product description/results, and my skin has not experienced any of the results. I will continue to use it, but as of now I think it's just a bit of an overpriced moisturizer and not anything special.
My face looks smoother than ever
HanaK from Alaska
I have struggled with acne and large pores for my whole life. I have never had smoother looking skin since using this product. I don't know what kind of magic is in this bottle, but I am never going back.
I still get occasional pimples, but my overall skin texture looks so much smoother, my pores look smaller, and my scarring has decreased a ton. I love the results.
Honey Bunny from Copperfield,TX
I had used before and saw a visible difference in my skin. But I had a rash after use. Also very gritty and smells different.
I like Khiels 1851 products and have always found them to be safe and effective on my sensative
skin. I'm also a chemo patient not sure if this why reaction happened.

I had an allergic reaction, but also had Chemo recently....... however I have used other
Khiels 1851 Products and very happy with results.
It makes a huge difference
Melissa from Waterford, Michigan
I love the way my make up looks if I use this product to prep my skin.
Pistachio from Arizona, USA
Reduces the magnitude and appearance of small superficial blemishes.
Certainly it has yielded an improved appearance of my facial skin texture and also produces a brightening/healthy look.
Very easy to apply, nonirritating, and does not impart a greasy feeling.
This is an excellent product which I have used for years and it continues to offer pleasing/beneficial results.
Visible difference right away
Whycantiusemyname from Miami, Fl
Ive been using a free sample for about a week now. Since the very first night there was a visible difference in my dark/tired under eyes! After just one week my face looks a lot brighter as a whole because of it! I don't even feel the need to wear as much concealer, such a nice feeling! I will be purchasing and I highly recommend.
MelissaAnn from Southern California
I'm 30 years old, I don't have fine lines or wrinkles yet, but I purchased this product to help refine my pores and rejuvenate my skin. I apply it only in the morning (I use the Midnight Recovery Oil at night and don't want to pack my skin with layers of products) and have used it for only a week, and I've already noticed a HUGE difference! The product is doing exactly what I hoped for. My pores are more refined, and my skin looks so much healthier and youthful! My skin doesn't look dull anymore, but looks refreshed everytime I look in the mirror. I LOVE this product and will continue to use it in my daily routine!
I thought I had found the one!
Steppy from undisclosed
Then they changed the formula. It literally hurts my skin to put it on, the texture is so granulated (and I don't have very sensitive skin). I loved this moisturizer for years, but sadly it seems that they are not responding to the multitude of reviews concerning the change, so I will be looking elsewhere once again.
Originally got as a gift came back and bought more
SarAhhhhh from Jax FL
Make sure to use it morning and night
Margs from MA
I have been using the Powerful-Strength Line-Reducing Concentrate for a few years and usually love the product. Bought a new bottle at the end of February and the serum has already oxidized with only a quarter of the bottle being used and kept away from direct sun and heat in my bedroom. This is the first time the product will not absorb into my skin and pills with layering moisturizers no matter what cleanser, toner or scrub combination I use. Highly disappointed and hoping this is a one off bad batch/bottle.
Penetrated my wallet not my skin
Chandler from Humid Texas
This was very topical in the sense that I didn?t find that it soaked into the layers of my skin whatsoever. It was very mask like and so that?s the way I chose to apply it at night as a sleeping mask. In the morning, my skin was left uneven, patchy and a tad dry. I think this is because of the (lack of) stability of vitamin C in general and not necessarily the formulation. Overall I didn?t find the product to brighten my skin and I won?t repurchase or recommend.
Sample sold me!
Amanda from Indiana
I use a lot of Kiehls products, and received this as a sample. I love it. The vitamin c concentration is perfect but doesn't leave that gross smell behind that other vitamin c serums do. Aside from that my acne red marks have drastically lightened and my skin feels very smooth. I use this after exfoliating a few times a week. Will always continue to purchase
Bad Break Outs!
LindZ from Austin
I use other Vitamin C serum brands, and thought I'd try this less expensive product. After weeks of use, my usually clear, clean skin began breaking out and developing blackheads across my cheeks and chin! I cleared up after discontinuing this product. I had to throw this away!
Elvina from undisclosed
one of my favorite vitamin C serum. non comedon and not make my skin yellow)
I would purchase this again
Msg Smith from Macon Georgia
After cleansing my my face I apply by pressing all over. Keep my face looking soft and smooth.
cmcgoo417 from Washington, DC
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.
Love this one SO much
Keshet from Israel
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.
10/10 would purchase again
Makeup for the ordinary from Oregon
I love that it wakes my skin up. It is reducing fine lines. It is a bit expensive.
Youth in a bottle. Absolutely love and will use for life
Rachael from Las Vegas
This serum is EVERYTHING. Immediately saw and felt a difference in my skin. Youth in a bottle. Will use for life
A little too thick
dandksmommy from Clovis, CA
I am searching for a Vit C product to add to my daily routine so I tried this one first and next I will try Lancôme's product since I have read such great things about it. This product itself is made of a white creamy weird texture formula. It feels like it has silicone in it. It has a super light fragrance which I cannot handle fragrance on my face, however this scent is truly light and non-irritating. I do think it's a bit pricey for the amount you get in the tube. Lastly, I have seen zero results. No lightening, no glow, no increased hydration. I will finish it up and move on to Lancôme & PTR.
Love this product!
Leezle from RI
I am Thoroughly Impressed with this product! Absolutely is my new Favorite and will be purchasing Again and Again!
Alfajor from FLORIDA
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?
