Key Ingredients
Vitamin C Glucoside
Vitamin Cg, or Ascorbyl Glucoside, is a Vitamin C derivative that activates once absorbed into the upper layers of the skin’s surface. With antioxidant benefits, this form of Vitamin C is frequently used in anti-wrinkle skincare products to help reduce facial lines over time.

Fragmented Hyaluronic Acid
This fast-absorbing form of Hyaluronic Acid is known for its ability to hold up to 1,000 times its weight in water. Acting like a sponge, it draws moisture into skin’s surface layers and expands as it absorbs. Hyaluronic Acid is known to help smooth and plump and is commonly used in skincare products intended to visibly reduce facial lines and refine texture.

The Kiehls Line Reducing Concentrate is a modest powerhouse. I purchased it out of growing discontent with my deep nasolabial folds, a byproduct of years of being underweight and sleeping on my side. I wanted my smile lines to be a bit less apparent, especially under makeup. Though I had heard great things about this product, I was honestly very skeptical, even a few days after initial use. About a week after I began using it, I still wasn't sure if it was doing anything. Upon studying my reflection in the mirror, though, I realized my lines actually did look significantly less deep, even when I smiled! I was amazed and am definitely a believer now.

One noteworthy detail about this product is that when you apply it to the skin, it gets quite warm- it's initially uncomfortable and may feel like a bad reaction, but it's all part of the process. Once rubbed in, the consistency sort of feels like putty or gum, and it doesn't seem to fully sink into the skin. It doesn't seem to have any hydrating properties, either: this product is exactly what it claims to be, nothing more or less.

On a final note, my favorite thing about this product is that whilst being effective, it doesn't irritate my extremely sensitive skin! My skin is highly reactive and usually hates anything containing Vitamin C, but this concentrate has not resulted in any breakouts or irritation whatsoever and seems pretty skin-safe in terms of ingredients.

I had high expectations for this product and was severely disappointed. I received a sample of this from the Kiehl's website, and was super excited to give it a try specially because as 30 creeps around I have noticed crows feet. Well, I used this for almost a week, and didn't even give it a chance to see any results because it irritated my eyes so much. I didn't get any in my eyes, but it seemed like my skin just did not want to absorb any of this at all. It made me a little more oily, and made my eyes water, and itch so so bad. I thought maybe it was my allergies, or pollen but the minute I stopped using this product that problem immediately went away. I still haven't picked it back up to retry, and still haven't had that issue since I stopped using it. Unfortunately I think I'll try something else.

Received 4 sample packets from Kiehls. I've tried it for the last week and I thought my skin would get use to this product, unfortunately it hasn't. I really wanted to love the cream because the kiehls brand is amazing. However, my sensitive skin cannot tolerate it!
1.) when I first put the cream on, it gets really warm on my skin. Then I get a tinging, somewhat burning sensation. I thought these symptoms would subside after using it for a week, but it didn't.
2.) the scent lingers on my fingers, even after I wash my hands.
Overall, I have sensitive skin and this product had too many negative sensations that I could not deal with.

I got samples of this in the mail, and I felt like it just made me more oily! It says instant brightening effect, but when I was on the way to work, my skin was so oily as if I just finished ten hours of work!! Keep in mind I work as a dental assistant, so I’m always active and am bound to sweat lol.

Application wise; the smell doesn’t bother me. It’s so thick, and it doesn’t absorb into the skin all the way. I only used half of one sample package for the daytime too. I’ll try it again, but so far, I am not loving it!

This stuff is AMAZING!!! received a sample from the company in the mail ( actually 6 samples ). U have to try it, smells great, my skin felt supple and hydrated for hours after applying. No sticky residue left behind. Expensive, so I dunno if I will buy, but FABULOUS product that really works on diminishing fine lines and wrinkles QUICKLY.

This product has changed my skin for the better. I have struggled with acne for a few years now and I have a few acne scars on both cheeks. I've tried everything to get rid of them but nothing has helped as much as this product did. 
My skin is clear and it looks so much healthier! My acne scars aren't completely gone, but the rest of face is so healthy that I don't even notice my scars anymore. I've been wearing less makeup because of it. I haven't felt this good about my skin in ages!

I was really excited to try this because I love vitamin C serums. It's great for fading acne scars/dark spots. It didn't irritate my skin when I first put it on. I applied sunscreen and the rest of my make up. I noticed throughout the day that my skin felt a little tighter than usual. That night, I noticed I had a couple red bumps on my skin. The only new product I had used that day was this concentrate, so attributed it to that.

I wanted to love this product because I heard such great things about it and Kiehl's in general. The consistency was quite thick and greasy which I didn't like. I stupidly didn't do a patch test and slashed it on my chest and face. The next day I woke up with tiny red bumps all over the areas I applied it. I have sensitive acne prone skin but have never experienced this reaction to a product. Very disappointed. Overhyped /over priced

Love this stuff. Definitely results with the worry line. Skin is immediately more smooth and brighter over time. It's powerful but after slowly adding it into my routine my sensitive skin seems to tolerate it. I do use this as more of a target area fix vs. an all over treatment. It may have caused a few irritation bumps on the apples of my cheeks but they are gone now that I only spot treat. Fragrance free, natural ingredients.

This really did not sit well with my skin. Not sure what it is about Kiehl's products, but I had A TON of small white heads all over my face after using this one day. The consistency is similar to CEO Sunday Riley and I haven't found either of these to layer very well. I added a Protini moisturizer on top and then sunscreen and makeup, and by 11 AM I was looking super greasy already.

I guess I just prefer my Vitamin C to be my base layer, so it must be very very thin. This was just much too thick and oily. Returned the next day.

Just bought this over the weekend...how often should it be applied? Morning and night or just one or the other?

I have read a few good reviews about this. I am on the fence about getting it. I am 30 years old, have normal skin with a little hyper pigmentation. Since I entered 30s, I have noticed some fine lines appearing around my smile lines and forehead. Should I go for it?

Should this be used after serum, before moisturizer? I thought it would be a serum, but it's much too thick.

I recently shared this sample with my mom, who is looking for an anti-aging product to fight marionette lines. She wants something with Vitamin C & is allergic to Tocopherol. Kiehl's Line-Reducing Concentrate seems to fit the bill so far... Have you noticed measurable results? After how long? Are there other products you like better? Thanks!!
