Rated 5 out of 5 by from Visibly improved skin I started seeing results in the quality and texture of my skin about 2 weeks into using. I use day and night and skin looks firmer, skin tone more even, and texture feels more smooth. It has a high price tag, but so worth it!

Rated 5 out of 5 by from Another great product to add to my routine I purchased this product a month or so ago, despite reading a review that indicated it had a very unpleasant smell. I am extremely sensitive to smells and it almost kept me from purchasing the serum. I decided, in any event, to give it a try, knowing that Kiehls would have accepted the return if indeed the product really did have a bad smell. I waited to review the serum to see if it really did make a difference in my overall skin condition. I have to say, first off, the fragrance in this product is not at all offensive, it is rather pleasant. second, I have noticed an improvement in my skin condition overall. To begin with, I have been using a mix of Kiehl's products for many years now and have zero complaints with the look of my skin, so I was not expecting much really, but I do feel it looks better. I am going on 76 next month and when I tell that to people, there reaction is always, "you have to be kidding, you look like you are in your 60's." Is that the products, genetics, nutrition, general health. I am sure it is the combination of all of those things, but I have also recommended the products I use to many other younger women who have thanked me profusely and raved about the improvement in their skin. This serum, I give 5 stars to because it warrants it.

Rated 5 out of 5 by from Consistency is key! When I first tried it, I have to admit that I was being stingey and was only using it once a day. I wasn't seeing that much of a difference until I caved and started using it morning and night. I have noticed that my skin is now supple and smooth! I have dry skin so this has helped to retain moisture better and has helped the texture of my skin.

Rated 5 out of 5 by from Good choice!! Im using this almost one month so i satisfied. When i using this a week i got some compliment about my skin :) only worst thing is smell but I've gotten used to it. Also i used vitamin c serum before and i remembered it was good so need time to decide which one i choose but new one is nice choice. It makes my face tone light and silky.

Rated 5 out of 5 by from I received a large sample of this from a retail store and I absolutely notice a difference in the appearance of my skin after using for two weeks. I was noticing how dull my skin was starting to appear and decided to commit to using this sample—my skin look brighter and I look younger. So much so that a couple of my friends have asked what I changed in my skincare routine. I’m so excited to add this to my routine permanently!

Rated 5 out of 5 by from Love it! Lightweight and wakens up the skin! I recently purchased this product for the first time and absolutely love it. It's light weight and I feel like it's "medicinal" with a light tingle similar to the Vitamin C Powerful Line Reducing Concentrate. I feel like it's brightened my skin! I use it for both my morning and night routine as the first step before using my hydro plumping serum (which I have also been a fan of for years!).

Rated 5 out of 5 by from Bye Bye Fine Lines My skin has a few fine lines under the eyes and around my mouth, along with some uneven skin tones. I have been using this product for 2 weeks and already noticed a difference in the look and feel of my skin. My lines are a lot softer and I can barely see the discoloration on my cheeks. The serum is very light and easily absorbed into my skin with no greasy feel. I use this mostly at night for hydration, and occasionally if my skin feels a bit dry (you can use it in the AM/PM). The smell is also light and refreshing - the product holds well under foundation if using with makeup.Kiehl's Vital Skin-Strengthening Super Serum

Rated 5 out of 5 by from visible difference! I started using this product every night a week and a half ago, and I cant already tell around my lips and forehead that my laugh lines are less visible! Im 28, but have a VERY expressive face, so the need for early age-prevention is real! The smell is great, a little goes a long way, and results are visible.

Rated 1 out of 5 by from It had no visible effect on my skin and seems like pointless product. I am a really loyal Kiehls user, almost 3 decades now, and so frequently I will try something new even though I have my favourite products, I gave this serum about 2-3 weeks. The consistency is a bit watery and the smell is overly floral. If the serum worked I could get past both, however, it did absolutely nothing for me so I returned it. In fairness, I have been using 3-4 Kiehls products daily for decades. My skin looks really great for a 57-year-old so maybe I have maxed out on returns from a skin product. If you are looking for a serum for ageing skin, you cannot go wrong with Powerful Strength Vitamin C Serum. It is one of the best things Kiehls makes in my opinion.

Rated 2 out of 5 by from Bad Smell This fast absorbing serum strengthens skin from within its deep surface layer. Helps resist signs of premature aging. Replenishes skin barrier for improved texture. I couldn't get past the smell. Then after using it left my skin looking worse than before using. I picked it up because I had good luck with several other Kiehl's products. This just didn't work for me.

Rated 5 out of 5 by from Absolutely Amazing There is no product like this one. I typically have loose skin and bags under my eyes and after using this every night, they're practically gone. A little goes a long way so the product will last a long time. I would 100% buy this again. Kiehl's Vital Skin-Strengthening Super Serum

Rated 4 out of 5 by from Skin best friend This Serum is a game changer for me, definitely a great product. I could see a big difference since the first time I used it. I like it

Rated 4 out of 5 by from Good Hydrating Serum I have oily skin but if I don't moisture enough then it feels dry within minutes after washing and throughout the day. This helped in adding moisture in my night time routine. Ended up not needing a rich night cream. The only thing is my skin feels super oily in the morning, not sure if it's due to this or the night recovery oil. I have used it for about two weeks, if any changes I will update my review

Rated 3 out of 5 by from This serum is fine. I didnt see much of a difference in my skin from using this product. I also didnt love the strong smell it has.
Date published: 2020-07-15
Rated 4 out of 5 by from Nice Serum This serum feels very nice upon application. It has a botanical scent to me, which I find pleasant. It layers well under moisturizer. The price is pretty fair for how long the product lasts. The main thing about it for me personally is that I would not be able to use this in my daily routine. I would probably use it just 2-3 times a week, as it does leave my skin feeling sort of greasy after regular use. I wouldnt say it feels greasy with one use, though. Its just my skins reaction to it over time. It feels supple, but that turns into just oil buildup if used too often.

Rated 4 out of 5 by from Super Serum I tried the Kiehls Super Serum and really enjoyed it. It was a nice addition to my skin care routine. I feel like it added moisture to my skin. It was a very gentle product. The smell wasnt extremely strong or off putting. I cant speak to if it made a difference because I honestly did not see any change in my skin. What I CAN say is that my skin is very sensitive and it did not cause any further irritation to my skin. Overall its a nice product that I would continue to use to see if it will affect my skin in a positive way.
Date published: 2020-07-08
Rated 4 out of 5 by from Nice Serum I used it for a month and it feels really nice when it's on I didn't notice any difference in my skin when it was freshly cleansed. It was gentle to my skin and felt silky smooth. It didn't have any harsh smells either. I like it but i wish I felt an improvement in my skin.

Rated 4 out of 5 by from Smoother Skin But Weird Smell I would recommend this product. Im not sure about the anti-aging properties, but this has made the texture of my skin much softer and more smooth. I dont care for the smell but it dissipates within a few minutes. Overall a good product, but pretty pricey. A little goes a long way though.

Rated 2 out of 5 by from not my favorite To be honest this wasnt my favorite. I didnt like how it made my skin feel afterwards so maybe I just have the wrong skin type.

Rated 5 out of 5 by from Love This Product! Just recently started using this serum, and it may soon become a favorite of mine! I love the natural, clean smell. I also love how it makes my face feel afterwards! Would definitely recommend!

Rated 3 out of 5 by from is it working? Honestly I was hesitant with this product because generally I like to keep my face clean and free of too many products. This serum Ive been using after cleansing, prior to a quartz roller and lotion and honestly Im not positive about its role in my skin care routine. I have gotten comments about my skin being radiant, but Im not sure if its this product or another one and I actually feel like by night time my skin more oily than ever, despite generally having normal to dry skin. Something is working, Im not sure if its this.
Date published: 2020-07-07
Rated 2 out of 5 by from so-so It isnt my fave face product. I think I use it the least out of my collection. I think the smell really turns me off-gives me a medicine type smell. The packaging gives me the same vibe. However, it doesnt make my skin oily (which is a plus)!

Rated 5 out of 5 by from love this serum I was never much into facial serums before but this one is different for me. I like that it smells natural while feeling lightweight and healthy on my skin. It has a very smooth texture and applies evenly, without making my hands feel slimy or sticky. What impresses me about this serum is that it penetrates the skins 8 surface layers, strengthening skin from within its deepest layer. The reason why this works better than most facial serums is because it is made with a herbal form of Hyaluronic Acid. Hyaluronic Acid is an antioxidant releasing ingredient that revitalizes our skin by providing weightless moisture. It helps to regenerate skin cells by repairing collagen levels. It goes to work by boosting skin elasticity; which helps lift, firm and smoothen fine lines and wrinkles. Its also good for reducing the appearance scaring. I have oily skin, and this is made to be safe on all skin types, including sensitive skin. So far its working great! All in all Im very happy with this serum and the quality ingredients used to make it.

Rated 4 out of 5 by from Hydrating! I received this serum complimentary and I was SOOOO excited to try because I love Kiehls! Being that the serum is a little pricey, I wanted to give it a good trial. I used the serum consistently for 1 month. Besides it being a good hydrated and leaving my skin looking plumper (temporarily), I didn't see much of a difference in the appearance of my skin. And also... I unfortunately didn't really like the smell. Overall, I feel like it's a good moisturizer but not a serum designed to create lasting change in my skin.

Rated 5 out of 5 by from Give your skin some LOVE! I absolutely love this product! Its so lightweight on my face, but has made my skin so strong. My skin was being torn from constant face mask and N95 use (Im a nurse! Wear your masks everyone, if I can do it for 13 hours in a row you can too!!) I applied this each day before work and my skin was so happy! I wish the price was lower BUT the quality is definitely on par with the price.

Rated 5 out of 5 by from I received this product complementary to try out and i love this serum! After a couple of weeks using this i started to see the result! My skin feel extremely hydrated, my pores were smaller, i would definitely recommend

Rated 2 out of 5 by from not worth the money I am such a fan of Kiehls products.. Ive used at least 4 tubes of the midnight eye recovery and can not get enough. But this i did not love.. did not even like.. I tried, really tried but I could NOT get past the smell! It smelled just like pickle juice. I did use this for one week and saw no noticeable difference that I could justify putting something that smells like that on my face. I did receive this as a free sample but I would not spend my own money on this product.
