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.

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.

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.
Rated 5 out of 5 by Tessatoo 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.

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!
Rated 1 out of 5 by Annie133238 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.

I use this product 2-3 times a week. I can feel my skin being softer and brighter in the morning after each use. It doesn't have any particular smell so I like it and it doesn't hurt my skin (I'm combination+sometimes sensitive skin). I have acne problems and I think this product helps me "refresh" my skin once in a while.

When ever I purchase a Kiehl's product, I make sure to stack up on some samples and the Overnight Biological Peel happened to be one of them. However, after using it, I was very disappointed. It's meant to be slept in, but this is so annoying to do. The product remains wet and sticky and so is your pillow as soon as you lie on it, and by morning almost all the product is now on your pillow instead of your face sooo this "amazing skin by morning" idea was not the case for me. In fact, my skin looked exactly the same as it did before I even used it. Anyway, I used the product 2 more times (I had more samples) and was disappointed after those uses as well - I even thought my dark spots looked darker. It was weird, so I had to go back to the Clearly Corrective Dark Spot Remover to rescue me. I was quite disappointed with this one, but I recommend trying a sample of this before purchasing the full thing to see how your skin reacts to it.
