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!

Katy K from Plano TX
I love this serum! I ordered after trying a sample and am very glad I did. I usually use another brand's Vitamin C serum and a separate hyaluronic serum that are twice as expensive. This Kiehl's combination is exceptional and very potent. I love the texture and the warming on my skin. I'll be purchasing this again, I can already see an improvement in my skin texture and color.
Doesn't get absorbed
Teri333 from New York
It sits on top of my skin and feels like a slippery coating all day. My makeup just slides off if I touch my face. Very unimpressed.
The serum changed color
Yomna moussa from Cairo
Got it 5 months ago but didn't use it.. now i can notice the serum it self is turned to be yellow not clear color, is it safe to use it or not? Please help
Vitamin C serum
Jnezelek from undisclosed
This is my first time using any serum but I did my research and purchased this because of all the benefits it has for my skin and because the price point is better. I'm glad I did! I've been using this twice a day for about a week now and I can already see a difference in the overall appearance, my skin looks and feels hydrated and looks plumper! Hopefully it'll help with some fine lines within the next week or two
It really works!
SailingChica22 from Long Island, NY
I don't often write reviews, but felt compelled to write this one after using the Kiehl's Vitamin C Serum for 6 months. I have seen serious improvements in the fine lines on my forehead and the vertical lines in between my eye brows. Honestly, it smoothed out the ones between my eyebrows and for that reason I am hooked! It really worked for me so if you are on the fence I would recommend giving it a try. The bottle lasts pretty long. I use one pump of serum nightly and the bottle has lasted me more than 6 m already.
2 for one!
Megmets from Detroit, MI
This product is a must have in your skincare routine! I initially purchased the smallest bottle to try, then I upgraded to the larger size when I was out. I have never found a product with such a high percentage of vitamin C, plus this formula includes hydraulic acid to seal in moisture so you're really getting 2 products in one! Your skin feels amazing right after you put on and really boosts brightness.
Ssl888 from California
I've been using this product for years, and it really worked.
RK from Ohio
I've been using this (almost) daily for the last ~5 years as part of my morning routine. I should be using it at night too, but I'll be honest, I'm lazy at night to have any sort of skincare routine. Anyway, as I've hit my 30s during the time of using this, I've not develops any of the lines you'd expect to see start during this time. Will continue to use and will recommend to everyone - the benefit justifies the cost to me.
Thick and Goopy
cwc121 from Portsmouth, NH
I always use a serum and was anxious to use this one based on what it is purports to do. When I think of a serum I think of a luxurious feeling oil or liquid that goes on smoothly and penetrates my skin feeling deeply moisturizing and comforting. This is none of those things. It is a very thick, goopy cream that doesn't feel at all moisturizing and doesn't seem to soak in. It is also so thick that I have to drag it across my skin which is not the least bit luxurious or comforting. I don't ever find that any skin products make that much difference in the inevitable aging of my skin, so I want what I use to at least feel good. I don't find that anything about this product feels good on my skin. I wish they would change the formula so this serum goes on smoothly and soaks into the skin.
I love this product!
Cheryl2911 from Misouri
I have been using PSVCS for well over a year and many mornings after I wash my face it is my only "go to" (along with some sun screen) before I hurry outside. I am 70 years old and have been told my skin looks great. I know it is specifically for fine lines but I use it sparingly all over my face and neck...love the way it feels and absorbs.
Thank you, Kiehls!
Feels great, satin finish
CK052020 from Raleigh, NC
I bought this a month or so ago and have been using it every AM/PM under my PCV Copper creams. I love the satin finish and feel like it has done a great job keeping my skin moistured.
Suni from Connecticut
I have been using this serum on daily basis for about an year, I don't see any difference in my forehead fine lines.
Samples work, Ulta!
KitSoCal from SoCal
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.
RBCK from Orlando, FL, USA
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.
Just Not For Me
Very Sensatative from Copperfield, TX
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.
