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 love serums. And I've tried a few glycolic acid and ive had good experiences. And I was excited for this although it being high potency made me be on the fence about it. Regardless I tried it out and I loved it. Maybe the first time you try it, it can be abit tingly so I'd say work up to it a little going a long way. But ultimately it helped my skin. And as always don't forget SPF after a product like this.
A welcome addition to anyone's everyday skincare routine

I love glycolic acid, the main ingredient in this product. Exfoliating ingredients are great because they slough off the dead skin cells on top of the healthy ones, revealing the healthy fresh skin underneath. This works well to fade spots and discoloration that I have. It is great for fading scars. I find that it also improves texture and firms. As with most serums, I love the ease of application with the dropper bottle and formula that easily melts into the skin. No scent which is also wonderful. Packaging is nice and clean but could be more eye catching. Overall I think this serum is wonderful and performs as advertised to reduce scars and discoloration, but it may be hard to compete with other offerings with the current packaging. It is a welcome addition to my everyday skincare routine.

I really like this serum. It works well and isn't too harsh on skin if you follow the directions for starting use.

I have a sensitive skin and breakout faster when I use new products. But I am surprised when I used kiehl's pure glycolic acid. It is very gentle and no stings or dryness. Feels fresh and cool.

It left my skin feeling fresh and light in the morning. It did give me a glow. I would advise to keep your skin hydrated after because I did see to get dry skin.
