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...

I have not used many serums, but I definitely will keep using this one after the results I've been getting! First of all, I really appreciate that this product is vegan and that its packaging is sustainable. But besides that, this serum is easy to use & fit right into my skincare routine. I used it at night because it says that it can make your skin photosensitive. I apply a few drops as directed and smooth it all over my face, and it truly does make you glow. It does make my face tingly but it's not awful. I can't say that it "minimizes" my pores but that's okay because pore size isn't an issue for me. Overall I would definitely recommend this serum.

I have been using this product continuously every other night. And I have been noticing a tremendous difference already. My dark spots have been getting a bit clearer, my skin looks and feels so much smoother. I also enjoy the consistency and packaging of the product. It's so good and I would recommend to anybody !

Overall this was a fairly nice product. It didn't have a heavy smell, no greasy or thick residue on the skin; and it helped my skin look better overall. I did take a star off because it didn't do much in the bigger problem areas, and I do feel like the ordinary has similar products at a fraction of the price, but I would still recommend this for how it worked and it's limited ingredients
Highly recommend
