HEPES (Hydroxyethylpiperazine Ethane Sulfonic Acid) 

HEPES, or Hydroxyethylpiperazine Ethane Sulfonic Acid, is a chemical buffer which is widely used in cell culture to maintain physiological pH. This amino-sulfonic derivative helps to improve skin and limits roughness.

Sodium Hyaluronate

Sodium Hyaluronate is the sodium salt of Hyaluronic Acid. It is used as a moisturizing agent, viscosifier and emulsifier. It forms a transparent film on the skin which has a soothing and lubricating action. It is a powerful humectant as it is capable of binding 1,800 times its own weight in water. See also: Hyaluronic Acid.

Urea

An enzyme activator naturally present in the surface layer of the skin (epidermis), Urea accelerates the natural process of cell renewal through the exfoliation of dead surface skin cells. The ingredient has a water binding effect in the top layers of the skin thus acting as a natural moisturizing agent in human skin.

Rated 5 out of 5 by Love it! I've used this overnight peel twice, and I've already noticed a difference in pore size and improved skin tone and texture. I've been guilty of not taking very good care of my skin over the years, sleeping with makeup on, smoking and not using the right products. Well, I've recently switched all my skin care products to Kiehl's, should have done it years ago! I've used LOTS of products, drugstore brands to high end, and nothing has performed as well as Kiehl's products. You actually see a difference quickly with all of the Kiehl's products, that difference really makes me want to use them like I should to see continued improvement! The Over-Night Peel is effective. I haven't noticed a sticky feeling, as other reviewers have, you really only have to use a small amount to cover your face and neck. I don't put anything over it, just cleanse first, then apply. I put it on a little bit before bed to allow it to sink in. In the morning, your skin will look great! BUY IT! Don't wait!! 5/20/16
Rated 4 out of 5 by I love this one I used to use this product before the Nightly Refining Micro-Peel Concentrate came out and I loved the results. I feel like the new version works a lot better and you see changes a lot faster - but that's just my opinion. I like the container that this comes in and love the pump. Still a valid product. Try it out! 4/28/16
Rated 5 out of 5 by Great I just started using this product. I saw and felt a difference immediately. Now that I have used it for a couple of weeks, my face is so smooth and even I really don't wear any foundation at all. I was blessed with young looking skin and this product has helped me keep it looking young. 4/21/16
Rated 4 out of 5 by Works Well Used this peel mask product for a couple months and saw some positive changes. Recently switched to the new Nightly Refining Micro Peel and believe the new mask (NRMP) performs better. Wondering if combining the 2 products is a realistic approach to achieving a more clarifying effect on skin appearance. Would appreciate feedback from Kiehls on that topic. 4/17/16
Rated 4 out of 5 by it's interesting I like this serum. I didn't think it would feel the way it does. Because it's an overnight biological peel, I actually expected it to burn or eventually dry up and in the morning i'd be flaky or something. Instead, it's an oily mask. I have oily skin, naturally. When I first used the mask, I just thought I was applying too much. I'm an African-American guy, so I use two pumps. The first pump gets my forehead a nose, the other, my cheeks and chin and neck. Probably because I have a low-cut beard. It makes my face itch a little bit. Not in a bad way or anything. Just like the feeling of someone lightly touching in your hair or on your skin and it makes you rub your hand across. I'm pleased with the results. I'm on my way to the porcelain, poreless skin I want. I rotate between the midnight recovery and this serum. Try it, it works. 3/27/16
Rated 5 out of 5 by Great product! I have tricky combination skin, and I had been using medicated acne products for a while that had worked really well originally but now left my skin feeling dull and tight. I was recommended to try this instead of a traditional exfoliator, so I took a leap and bought a bottle of this. Love it! I know some reviews complain about this being too thick, not absorbing, and leaving marks on their pillows, but this hasn't happened with me at all. I can see how using a lot of it might do that, but a little of this goes a long way. I use a half a pump two nights a week, and it absorbs very well and has never stained my pillows. I've already seen a noticeable difference in my skin in two weeks of use. My boyfriend even commented on my skin yesterday; he said my face glows and my skin looks fresh. It's seriously a great product, at least for me. Definitely pricey though, I wish it were cheaper, but you don't have to use a lot so the one bottle goes a long way. 2/15/16
Rated 4 out of 5 by Tacky but terrific Try and sample and see if you can handle the tacky feeling overnight along with the pillow deal that so many others posted about. Using it regularly really does make you look tighter and smoother with smaller pores. It's fabulous. Rotate with midnight recovery serum and you can take all that money you were going to use on laser treatments and treat yourself to a day at the spa! 1/13/16
Rated 1 out of 5 by This serum doesn't do anything to me Excited to try this product, but disappointed the first week, being patient used a couple more weeks, still doesn't do anything to me, not like kielh's other products. Bought it online, couldn't return in store. No time to wrap up bring to the shipper. Anyway, I wouldn't recommend it. 11/29/15
