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.

SO-di-em HI-ah-loor'uh'nayt

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.


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.

GERTRUDE W. R: I would suggest using the peel first and solo for a few days. Once you see how much exfoliation occurs, apply your serum every 2 days. You want your skin to fully exfoliate (peel) and follow-up with the serum on a clear facial palette - the serum will be more effective. Mar 4, 2013

GERTRUDE W. R: I would suggest using the peel alone (at night). Once you can gauge how much exfoliation occurs, then apply the moisturizer.

A shopper asked: Can you use with retin a? Apr 22, 2013
Answer this · Send to friends Good question? Yes (1) No (0)
Jamy K: Do not combine! Retin A is a prescribed topical medicine. It also works by sloughing off layers of the skin however at a much higher rate. Combining the 2 or even switching back and forth may cause inflammation along with frustration. I understand the desire to exfoliate, you may want to use a mild facial cleanser in the mornings that contains AHA or BHA along with a soft facial brush or pad using circular outward motions. always remember to hydrate and use suncreen. if your skin needs to calm down i do recommend the calendula/marigold toner that kielhs has.

Keri L: No. It works more like a night cream. I put it on after my cleansing routine each night and since the weather is warm now I don't feel that I need to put on additional night cream.

Mimi N: I don't have a frequency recommendation, except to follow the directions on the label and to pay attention to how your skin responds; I use this peel about once a week because I often use glycolic acid products at night, which are pretty strong.

No, your face should not peel or be flaky in the morning. When I wash the product off, my skin feels smooth and supple.

Erin H: I would not use any "peel" (neither biological nor chemical) product on the under-eye area. The skin under the eye is much thinner and therefore more fragile and sensitive.

A shopper asked: How can i used this peel with my cc dark spot solution? May 22, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Angela W: The C.C. Dark Spot Solution should be applied after you use the toner and before you apply moisturizer or lotion. The Over-Night Biological Peel probably is best used as a stand-alone--AFTER you cleanse your face. The peel is to be worn over-night and then washed off in the morning. What I do: cleanse, toner, over-night peel. Since I only use the over-night peel once per week or two weeks, not using the C.C. Dark Spot Solution that one night is no big deal (especially since I use the dark spot solution twice daily). Jun 21, 2013

Richard asked: I use benzoyl peroxide in my regiment due to my acne and i tend to break out whenever I don't use it at night. Is there a way of applying BP and then putting the over-night biological peel on? Mar 13, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Jamy K: I wouldn't recommend using both products at once as part of your nightly regimen, you may tend to over stimulate your oil/sebum production and then may lead to nice rosy patches where you didn't want to draw attention, your face. use the peel on clean skin, allow to absorb, follow with your moisturizer. think of it a a vacation day/night from your BP. If you're like me and experience oily skin I also recommend changing your pillow case frequently. I personally use cotton or linen and change them every 2 days so i'm not sleeping on the same surface. also my face cloth i change 3 times a week. May 2, 2013

GERTRUDE W. R: Janina M. your question is a very good one. I can relate because I do the same - switch off to different treatments. I think Kiehls ONB Peel is very effective. It is not as harsh as Retin A but does create a good peel which allows exfoliation. Mar 4, 2013

donamarie M asked: Is it possible to try the Over-night Biological Peel on my sun-damaged arms? Also, I had used the hand cream called"Unusually Rich--But Not Greasy At All--Hand Cream, with SPF 10. Now, I cannot locate this at Kiehl"s at all. Jul 4, 2012

Leesa T: I can't imagine doing any harm except to your wallet since the arms are a much bigger surface to cover than the face. it's a good product but no miracle for sun damaged skin. like many biological peel products, results largely disappear with continued sun exposure because they partially remove the uppermost layer of skin to reveal newer layers than can be more vulnerable to UV rays.

Mary W asked: What is the procedure to use the peel? Apply and leave on over night? Scrub it off? Just how does it work? Jun 16, 2012

Daniel L: You apply and leave it on overnight. I usually do full coverage on my face. It doesn't dry like a mask which is good. So you still have the ability to eat etc without it feeling like it's dried up. Next morning, you just use a facial cleanser to remove it. After using it for a while, you'll notice some affected spots on your skin get better. Jun 16, 2012

Boya D: I bought this about a month ago, and continue using it for about 2 weeks. For me, it does not really help with my acne scars, and neither fit my skin type (oily combination), I still have pretty much a lot of problems with my skin. Jun 7, 2012

Jesse T asked: I received a couple samples of this peel. I used the entire sample pack on my face and found it to be sticky the whole night. Is that the recommended amount to be used each time? Just wanted to be sure before I buy a bottle of it. Jan 23, 2014
