Rated 5 out of 5 by from Worked Great for Me I was convinced after two nights of the trail. I was breaking out in a newly humid tropical environment and needed a solution quick. Luckily, there was a Kiehls nearby and I went in for a consultation. I bough so spot correction, but the guy advised that I use the micro-peel and the toner. The toner was an easy sell because it was cheap but I wanted to try this peel before dropping 50$ on a one ounce. I was a bit confused about the process of things; when does toner go on, after or before the spot correction? But the Face Consultant got me clear. Put on the peel last after your routine before you sleep, leave it on overnight, then wash off in the morning. It is a little sticky but not unbearably so. It's as if you have camp face (not having showered after camping). This product delivered for my normally oily skin. I'll be using twice a week--not nightly. Now I'm ready to drop 50$

Rated 5 out of 5 by from Awesome Product I love this product a lot. After using for a few days, I noticed an improvement in my complexion. It is now a must have on my daily routine!

Rated 1 out of 5 by from no effect I was so upset, everyone is boasting about this product and it has done absolutely nothing for me. I kept reading about the amount you use which I have been trying to get right but I feel like I just wasted $60 bucks. Pitiful

Rated 5 out of 5 by from Amazing on Acne Scars! I've been using this product with the midnight concentrate, as suggested by many other users, for about a week. My skin looks amazing! A lot of stubborn old scars, I'm talking YEARS old, are starting to fade. My overall skin complexion is a lot smoother, and a lot of my dark spots are starting to fade as well. Honestly, wish I had tried this product earlier, because my skin has not looked better! Of course, I use other products in conjunction with this. If you scar easily from acne, you HAVE to try this in your night time routine!

Rated 1 out of 5 by from No for sensitive skin It burns if you apply it too often. Gave me bumpy forehead and skin irritation.

Rated 1 out of 5 by from First Kiehls Product I do not like It goes on sticky, and does nothing for the texture of my skin. In fact, I dont like the texture when I wake up. my skin is still sticky and tit does not look refreshed. In fact, I think it exaggerates some imperfections. Ive been using the product for a week now and will need to go back to my retinol night cream.

Rated 5 out of 5 by from MUST HAVE I randomly chose a sample of this from a purchase months ago. I found my bag of samples and thought, why not? I have extremely sensitive and dry skin on my face and thought I had made a mistake after seeing how red and warm my cheeks were- little did i know that in the morning my skin would look amazing! It smooths everything out, my skin is not dry and it makes my pores look like I've never worn a day of makeup in my life. Looks like i'll be making another purchase soon!

Rated 5 out of 5 by from awesome i've been using this product in conjunction with the midnight recovery oil and my skin looks awesome. it's hard to isolate if the improvement is from this the nightly refining micro-peel concentrate or the midnight recovery oil or the combo of both, but since i've been using them both each night, my skin looks soft, some acne scarring i have on my forehead & cheeks looks smoother and less noticeable, and my breakouts are mostly cleared up - almost every aspect of my skin has improved. i have pretty sensitive skin - i break out easily but also have a lot of dryness in the winter - and this product combination didn't cause either my breakouts or dry skin to act up; in fact, it seemed to address and sooth both those problems simultaneously. will def continue this night time routine for as long as i live!

Rated 5 out of 5 by from Great Product I absolutely love the product! After 1 week my skin was so smooth and others noticed too. The only reason I gave this product 4 out of 5 stars was because of the price. Its a little sticky once it dries but its worth the result. No one ever said good skin was going to come easy.

Rated 5 out of 5 by from small, weird and gross price to pay for smooth skin.. I received the smallest vile of this product as a sample. I used it one time and went back the next day to buy it. I could tell the next morning while washing my face how smooth my skin felt and looked. I have never thought I had rough skin but the difference in before and after using this product is remarkable. its a good product but it is a weird, and sticky product too. Your face will stick to your pillow case. That's a small, gross and weird price I'm willing to pay for skin that feels and looks super smooth. I even tried to get a coworker to feel how smooth my face was but she flipped me off, I'm pretty sure she's sold though. She needs it worse than I do...her skin resembles a pilling wool sweater.

Rated 3 out of 5 by from Miss the Old Peel This peel is SO sticky and the feeling didn't even really go away after it dried. That alone was sort of a deal breaker for me. I didn't notice enough of a difference to make up for the weird consistency. I was especially disappointed since the old peel was so amazing. This just fell flat for me.

Rated 5 out of 5 by from Love this product I absolutely love this product. I am an avid Kiehl's user and when the woman at Nordstrom told me how great this product was, I wasn't convinced.They are always hyping up new products and I never know whether to believe them. But it turns out, this one is legit. I find that when I use it before bed, my skin is so smooth and clear in the morning. It really makes a difference. I typically wash with the calendula cleanser, use this, and follow up with midnight recovery oil. When my skin is dry, I add a moisturizer on top. I am 28, pregnant, and have combination skin. I'm liking this routine!

Rated 5 out of 5 by from Flawlessly Effective Initially, I was not excited by this release because I felt that I already had enough products to rotate in and out of my bedtime routine and that it was just a new version of the Overnight Biological Peel. Wrong. This is a sensational product, one that peels and exfoliates gently overnight. Best of all, it is gentle to be used daily and can be layered under a moisturizer; the Overnight Biological Peel must be used alone. From the first use, this product's virtues were evident the first morning. I like to use the Powerful-Strength Line-Reducing Concentrate with the Midnight Recovery every other night, and this product on the other nights. My skin is already pretty good, and this takes it to the next level. Lastly, don't be put off by the price: this bottle should last almost a year, if not more.

Rated 4 out of 5 by from Noticed Less Breakouts! I have hormonal acne and was breaking out with a new pimples everyday. This includes cystic, whiteheads, blackheads. You name it, I got it . Ihave tried multiple products and have read multiple reviews of different products that will say the following: OMG THIS GOT RID OF MY PIMPLES IN A DAY AND I WOKE UP WITH COMPLETELY CLEAR SKIN! Before I was naive and would buy the product and think I would wake up with completely clear skin the next day. Now, I usually roll my eyes at these reviews because nothing has ever worked for me in a day. I have been using this product for about a week and a half and have noticed less breakouts. I have not been getting the larger pimples I was seeing every morning when I would wake up. On one my side of face, I have noticed no new pimples. Has this cleared up all of my acne? No, I am still getting some smaller pimples. Has this product helped my acne? Yes, I will continue to use this and I can't wait to see the results after a month of using this. A week and half is not that long to know how well this is going to work in the long run so I am going to continue use this everyday for a month and come back and update everyone on my progress. I say take the plunge and buy this and see how it works for you skin! Good luck! :) NOTE: When I talked to the sales lady, she told me that this is supposed to be used with the midnight recovery oil which gets rid of the sticky feeling. She said to apply the micro peel first and let it dry for a minute an then apply the midnight oil.

Rated 4 out of 5 by from nice product I have enjoyed this product so far. I have used almost the entire bottle of this product and decided it was time to make a review. i am acne prone and oily so i thought that i would try this product out to see if it would help my acne. I don't know how well it prevented acne for me because I still continued to get some acne, but it did help prevent acne scarring and made my face soft and helped to remove dead skin and brighten my skin. the consistency of this serum is also nice because it is easy to spread onto your face and goes on nicely. this is a nice addition to your skin routine but I wouldn't say it is a must have.

Rated 1 out of 5 by from So sticky and zero difference in my skin :-( First, I am 40, almost 41, I have normal skin, sometimes a little dry around my chin/neck, and I have been using Kiehl's products since I was 17 years old and my skin shows it. I get compliments all the time and people ask what products I use and I am proud to say: 'KIEHL'S'!!! It amazes me if someone hasn't heard of the brand! As far as serums go, I use midnight recovery religiously. I also use the newest addition to my routine, the Daily Reviving Concentrate in the morning (LOVE). The reviews I read regarding the micro-peel concentrate were so good, I requested a sample & I liked it. I mean, I only used it for 2 days because that's how much the sample had. Simply put, this product was very disappointing. It is so sticky, I couldn't stand the way my face felt after applying it. Midnight recovery is polar opposite... I was finding myself rinsing my face it was so sticky. Literally: My face was sticking to my pillow. Yikes. I am calling Kiehl's online today to see what they can do, as I need to re-up on a few products.. But this one.. Even when I did leave it on? I felt and saw zero difference in my skin tone or texture. I hope others had better luck! :)

Rated 5 out of 5 by from Hormonal acne solution for me! Thai product is amazing! I have been experiencing hormonal cystic acne since February along my jaw line (and I have never had acne problems before? Happy 26th birthday to me) I saw a review for this product on here and that it works well for this and it does!!! This product cleared my acne in a week and has lightened the scaring from the acne, which is just crazy to me. My girlfriend has been using it too and has noticed similar results. I have been a Kiehls loyalist for a couple years now and now I'm an even bigger fan than I thought possible. The product is more expensive than what I normally would like to spend, but it works so well I don't even care.

Rated 5 out of 5 by from Great addition to my skincare I am a huge fan of Kiehl's. I have been using their products for years while living in different climates and at different points in my life. I currently use the Ultra Facial Cleanser, Ultra Facial Cream, Creamy Eye Treatment, Daily Reviving Concentrate (for day), and the Midnight Recovery Concentrate (for night) on a daily basis - along with exfoliating and toners and masks all from Kiehl's. I received a trial of the Nightly Refining Micro-Peel Concentrate and really like the results. It is a little sticky when applying but has a lightweight feel when it is absorbed in the skin. I have not been in the best of health and my face showed it - I didn't think much could be done to improve it. With the use of the concentrate, I have noticed that my skin looks fresher and has evened out my skin tone. I follow with the Midnight Recovery Concentrate and eye cream. Great results!

Rated 5 out of 5 by from Changed my skin! Background info: 20 yr old, female, dry/acne prone So this product takes a few weeks to work and at first I was totally disappointed but I chose to give it a chance for a few weeks. I have dry, acne prone skin and I've been fighting bad hormonal acne all around my chin and cheeks. After using this product for 4 weeks, no joke, MY ACNE IS GONE. I also get a ton of white heads all over my face which make my skin's texture super rough and very noticeable in the harsh sunlight. This stuff smoothed out my skin like a babies butt. I used to never be able to look into a mirror close up without wanted to break the glass. But believe me...give it time. It works! The only con would be that it can be sticky. When I first started using this I was using way too much and it was crazy sticky. Only 4-5 drops for the whole face will do! Dont over due it, it wastes the product.

Rated 5 out of 5 by from Works really well, love Kiehls I have been using this new product for over a month, waited to see the effect. It worked as it describes. It is a little sticky after I apply it to my face, but my skin tone is more even now, and the acne scares are fading away. I can't believe that something can actually help with my acne scares since I have been fighting that for many years. I would definitely add this product to my lifetime skincare product list. I am really committed to Kiehl's now.

Rated 5 out of 5 by from Buy it! After many years of not taking very good care of my skin, sleeping with makeup on, smoking, not using the right products, I recently switched all my skin care products to Kiehl's. I just wish I'd done it years ago. I've spent LOTS of money on many different products over the years, drugstore brands to high end products, nothing ever worked. Well that's all changed with Kiehl's! The Nightly Refining Micropeel is one of the best Kiehl's products I've tried. I have softer skin texture, more even tone and a kind of a glow after using for about 3 weeks! I cleanse, then apply the Micropeel with Midnight Recovery Concentrate over it and then Ultra moisturizer. My 52 year old skin has never looked or felt better, fine lines are smoothing out, and the dark spot I had is much lighter in color. Don't wait any longer, just BUY IT!! You won't regret it!

Rated 4 out of 5 by from So far so good... I didnt want to write a review until I used this product for at least two months. I am getting married in August and I wanted to possibly do a few chemical peels for my face leading up to the wedding. Unfortunately peels are not budget friendly and I would rather spend a few hundred dollars on extra flowers then on two chemical peels. This serum has been an excellent alternative. While its not as fast acting as a peel, with consistent use over time I have noticed better clarity in my skin. I have some hyper-pigmentation on the apples of my cheeks that I have noticed in the past two weeks is showing improvement. I also use this product in conjunction with the dark spot corrector so I believe its a great one two punch. I am very excited with the results so far and I believe with continued use it will get better.

Rated 5 out of 5 by from LOVE LOVE LOVE I've been using the Midnight Recovery cream, Midnight eye cream and the avocado eye cream for about 2 years. People have noticed my skin texture and overall appearance. BUT THEN I ADDED the nightly refining micro-peel. I use this 1st, then the eye cream, then the recovery cream and then slather my eyes in avocado eye cream. Within 2 weeks, people have stopped me at work to say how amazing my skin looks....and that's without ANY make up. I sent this regimen to 3 clients and they LOVE it too! You won't notice an overnight change, but in time, your skin literally glows. I am a Kiehl's girl for LIFE. Oh yeah, I'm about to turn 40 and I was carded at the liquor store last weekend and at a restaurant the week before that!

Rated 5 out of 5 by from Acne no more. This is an awesome product. I have acne and acne scaring, this is a great product and my acne has almost gone away and the scaring is clearing in less than two weeks. I know this is not an acne product but it helps gently shed the dead skin from my pores and helps keep my face clear. I use about half a dropper full at night. I use that much because I also use it under my chin and neck where I have some scaring. I do think the product is a little expensive, however if it keeps my skin clear and I have to buy less of other products then to me it is a good deal. Give it a try for a week and you will see a huge difference.

Rated 5 out of 5 by from One of my most beloved steps I use this product after my toner (the blue herbal lotion). The first time I used it, was because I was offered it as a sample with the purchase I made in store. I cannot say enough amazing things about this product. Before I started using Kiehls products, I had terrible acne, and it left marks on my face. In just one use when I woke up in the morning, the marks were DRASTICALLY reduced. I realized I needed to purchase this and start to use it in my nightly routine. I just love love love this product. After I put it on (it is slightly sticky until it dries) I let it dry, then I use my midnight serum, and my kiehl's moisturizer. I'm now two weeks into this, and all of my acne marks are gone. Thank you so much Kiehls, phenominal product.

Rated 5 out of 5 by from It Works!!! I have been using this product for 3 weeks. And it works amazingly!!!!! My skin has been getting better and really smooth. The size of my pores are so much more smaller and it helped me lighter my acne scars. I dun need to use foundation no more. I just need to apply sunscreen everyday and eye make up before i go out. I use this product every night after my sk-ii toner and before my kiehl’s night oil. They work perfectly together. I am so happy my acne scars are actually going away and faster now i used a lot of products before didnt help my acne scars fade away at all but now i really can't believe it what i am seeing morning!!!! Love it!!!

Rated 5 out of 5 by from Superbly Effective Nightly Refining Micro-Peel Concentrate creates a potent extract to increase surface skin cell turnover with Quinoa Husk Extract as their main ingredient. Unlike other peels, your skin isn't going to literally peel like skin from a sunburn. However, it is going to do a light exfoliation process during the night, so by the time you wash your face in the morning, all the dead micro cells are being washed away. It takes 28 days (or so) for a cell to live its full life. Once the cell dies, it just sits on top of the skin (epidermal) and chills there until there is some kind of force to remove it. Highly recommend this product. Still can use this product with your normal Serum, Midnight Recovery, and under your moisturizer.

Rated 5 out of 5 by from Fantastic Results I'm already a big fan of Kiehl's and use a good bit of their products, but this has been a fantastic addition to my nightly routine. The product goes on a little sticky, but after a few minutes, I layer on my Midnight Recovery Oil, Facial Fuel moisturizer and an RX gel. After the first day, my skin felt a little more soft, but after using every night for a couple of weeks now, my skin looks radiant and healthy with a more even complexion, visibly smaller pores and softened fine lines. My face thanks Kiehl's for another amazing product!

Rated 5 out of 5 by from Great Product A good product for helping clear skin of marks/discoloration (etc). Very gentle, not sure why its called "peel" because the skin doesn't really peel. I have been using this product for about 3 wks and am very pleased. The screen states received sample - I DID NOT, I purchased the product. Important point for marketing: You need better demo's - NONE of the product demos really help because the people aren't really using the product and its obvious. Make videos with people ACTUALLY USING THE product to show consumer HOW TO USE it!
