Rated 4 out of 5 by Midas 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!
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.
Rated 4 out of 5 by Jasmine younger skin
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.
Rated 2 out of 5 by Kryssie Eh..
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.
Rated 1 out of 5 by Valleri Don't see any results
really... not sure how long should i wait to see any results . My skin is very sensitive and i was looking for a peel that not is gonna be too strong for my skin. So i chose this one. The texture is weird. Its too thick and its not comfy to sleep bc it stays on my pillow case ... And i think it makes my skin even worse. I will try to use it longer but i feel bad paying this much and don't get any results . Really happy for those who does see it.
Rated 4 out of 5 by Yellow323 My doubts vanished...along with my pimples, flaky skin, & fine lines!
I got this as an alternative to using Retin A while pregnant. With the first couple of uses, I was skeptical. The texture is thick & tacky & it never really absorbs into my skin. I honestly felt like more was rubbing off onto my pillowcase at night. After a solid two weeks of usage, at 3xs per week, I have to admit that any doubts I had about this product vanished, along with some pregnancy related pimples, flaky skin, and fine lines! My skin feels smoother, looks tighter, & is more luminous. So happy to have found this product! Will continue to use it after the baby is born!
Rated 1 out of 5 by Lisa20 Parabens?
I was excited to try this product. It came as a sample with my argan hair pak (which I love). I read all the reviews and couldn't wait to use it. Then I read the ingredients. I was not excited to see that this product has 4 different parabens in it. Unfortunately, I will not be trying it.
Rated 5 out of 5 by Eliza Effective results
The serum is effective when used consistently - the results are gradual, which is preferred rather than over drying.
Product made my oily skin more evenly toned and improved the texture and feel.
