Not for sensitive skin ...
Upon receiving this complimentary product, I was super excited to finally get a chance to try a Kiehl's brand product. The Kiehl's Ultra-Pure High Potency Serum 9.8% Glycolic Acid arrived in a semi-sturdy red and white branded package with black lettering. The serum is enclosed in a small glass bott...

Good ingredients but didn't work well for me personally
This is the second Kiehl's product I've tried and wanted to love but just didn't have success with. The ingredients are simple, the packaging is understated and clean, and the serum is clear and watery, so in theory I should have been able to layer it under my moisturizer. For me, the product was ve...

First of all I love the bottle because it isn't so thin that I feel like I'm going to drop and break it. It is a thick, high-quality glass with a well-made and excellent dispensing dropper cap. As for the product itself it is scentless and works very well to keep my skin clear. Since using this product I have noticed a brighter, more even complexion and less breakouts. Overall, I feel Kiehl's really never fails! I highly recommend this product to those with dull or acne-prone skin, and I do see myself repurchasing this product in the future.

This product has been great for my skin and has been a great addition to my current routine. I was able to use it for about two weeks before this review and since I do not use it every night, it works out to be about 6 uses. I have used a similar product in the past, but not within the past 6 months. I really am happy to know that there are only 7 ingredients and you don't have to read a novel when looking at the list! My skin feels great the morning after using and throughout that whole day. I have sensitive skin and not once felt like the exfoliation was too much for me.

I am definitely loving the Kiehl's Ultra-Pure High-Potency Serum 9.8% Glycolic Acid. I suffer from some enlarged pores and textured skin on my face, and after using this every night for for the past 3 weeks I have definitely seen a difference. My pores are less apparent, and my skin definitely looks and feels smoother. I would definitely recommend adding this to your skincare routine.

I was surprisingly impressed with this product! I appreciate that they packaged it in a glass jar and I love that it's made with only 7 ingredients. A little bit of this product goes a long way and I did start to notice a smoother texture on my skin fairly quickly. I use one drop at night and only apply it to my cheeks and forehead. It doesn't have a scent, it absorbs quickly, and feels very hydrating with a moisturizer applied on top.

This serum is in fact texture smoothing! I have been testing it with my skincare routine alongside my liquid exfoliator, and I've tried it on it's own. It applies easily, absorbs pretty quickly and is a bit tacky to the touch as it absorbs into the skin. I have oily/combination skin and I've been focused on skin texture lately. This was the right product at the perfect time and I'm loving it so far!
