I finished the whole bottle before leaving this review. I really liked how lightweight it felt on my skin and that it layered well in my routine without feeling sticky or heavy. However, I did not notice much of a visible difference in my skin texture or overall appearance.

I’m waking up after my second night using this serum and I truly, honestly, cannot believe what it’s done in 2 days. I generally have large pores, dry skin, perioral dermatitis, I’m sensitive thanks to a vulnerable skin barrier (I’m on spiro), and I deal with rosacea/redness. I’ve woken up two mornings in a row now to see: dehydration lines reduced on my forehead, active breakouts cleared, even skintone/very little redness, and my pores are MUCH smaller. Like MUUUCH smaller - I’m baffled. I’m sorry to be dramatic and I swear on my cat/the love of my life that this isn’t an incentivized review. I bought this with my own money. If you struggle with sensitive problem skin, you’re not seeing big changes with other approaches, and you’ve been nervously avoiding peels for fear of making things worse - I really do suggest giving this a try!

I absolutely LOVE this product. I wanted to start using some type of peel/retinol, but was really hesitant because I have very sensitive skin, and breakout very easily (I have combination skin). I purchased this after reading all the amazing reviews, and I’m so glad I did. I follow this up with two other serums and a moisturizer, and have never had any issues with burning my skin. I do use it daily, too! So worth it, even for the price.

I bought this product myself and am not incentivised to write this review in any way. I've been having an absolutely terrible outbreak of hormonal acne, I haven't broken out much at all in the last 6 years honestly, and one product I used made it even worse. I usually use Drunk Elephant T.L.C Framboos but it's so expensive I had stopped using it and was looking for another AHA/BHA serum before making the commitment again. This was 25% off and I like Kiehls a lot so I decided to give it a try. I definitely noticed some improvement the next day in the redness and smaller breakouts and it slowly is helping clear up the rest. I still have one or two new breakouts after almost two weeks of use every other day but compared to before it's a big difference and am sure with continuing use that will improve further. I only put this along my jawline and I usually use an AHA/BHA serum there twice a week but I do have sensitive skin and could manage this daily if I wanted. That being said always patch test and start slowly. I like to mix my acid with my hyaluronic acid serum to help with sensitivity and help "extend" the more expensive serum but I will say this is very watery for a serum, almost more like an essence, so I put on the hyaluronic acid serum then very gently pat this in on top. I use more of the product than I'd like for that reason but it doesn't seem like the product has dropped much in the bottle and ideally I'll get to just using this twice a week so for now I'm not worried about it. It smells a bit but I appreciate that it's not fragranced and I have noticed glycolic acid smells bad in general. I will say it lingers a little which is my only other complaint honestly. Definitely my new acid serum would repurchase.

I've been experiencing hormonal acne and have tried so many products to try to address it. I purchased this because it had great reviews and was described as a gentle daily peel. the first few days my skin seemed to like it but then day 4 I woke up with what appears to be a chemical burn on my cheeks and jaw line. It is so red, textured and itchy and my skin feels tight and extremely irritated. I do not recommend daily use for sensitive skin!

I’ve been using this product for almost 2 months now &it will stay in my routine! I enjoy trying different skin care products to see what gives me great results & this one has given me smoother, brighter, acne-free skin. I have very oily skin which makes it hard to find the right products especially sunscreen. However now I know I can use my fave sunscreen(Dr idriss disco block) & not worry about tiny bumps & bad textured skin!!! I have even added a thick nightly mask (summer fridays jet lag mask)to rejuvenate my skin at night & I have had ZERO issues with oil & acne. This is my breath of fresh air :)

I have super sensitive skin and this thing is amazing!! No irritation and skin is so smooth. Also no breakout since at all. Highly recommend if you are looking for a pre-treatment for your sensitive, acne-prone skin.

I wanted to like this with the good reviews it has, but I feel that it doesn't do anything for me. I've been using it for a few weeks now and I thought it would help with my pores since it popped up under pore care. My pores are the exact same and I see nothing different whatsoever. Waste of money.

I had high hopes for this but after a week of using it started to break me out:/ I have closed comedones on my cheeks and I was hoping something like this would help and it didn’t. I also have pretty large pores on my forehead and under eye by the nose and it just didn’t do the job… I am a DIE HARD kiehls loved and use all of their stuff but this one was a no:(

Love this!! My skin texture has improved drastically. I also have sensitive skin and it has never made my skin feel stripped or too dry, especially in the colder months. Highly recommend!
