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...

Great Serum

I really enjoy using this serum during my nighttime skin care routine! The consistency is thicker than a lot of serums and doesn't immediately soak into the skin, you have plenty of time to apply it to the desired areas. There is no scent, which is perfect for sensitive skin types. I enjoy all the benefits it has to offer and I have seen a pleasant difference in the skin texture over the past week of using this daily.
Amazing

This product is amazing and changed my skin to make it smooth and bright. I suffered with bags and this cleared them up in a week. It's like a mild chemical peel that promotes new skin cell growth.

Works well, definitely need to slowly start using the product since it's pretty strong. I definitely over multiple weeks have noticed a difference in my skin texture / general congestion. My boyfriend has been using the product as well and after slight mishap with using it too often at the start he has enjoyed the product as well and he has much more dry skin than myself. Overall not sure if I would purchase but definitely will finish using, and would consider purchasing again in the future.
My favorite glycolic acid serum

This serum is very good. Makes my skin soft, the texture on my acne prone skin has decreased drastically. I can see clearer bright and glowing skin. I have very very sensitive skin and this does wonders to my skin. Plus the packaging is sturdy; with dropper its a time saver. Absolutely recommended.

I like this glycolic acid and use it on a cotton pad to wipe down my face after taking off my makeup. It makes my skin feel refreshed
