Effective
Makes my skin supple and healthy looking. Very light and non-greasy. It does not have any scent and packaging is very elegant and easy to read. Good product!

KIEHL’S Glycolic Serum 30 ml
This lightweight serum has only 7 ingredients—and 9.8% pure glycolic acid. Here’s what I noticed after a few weeks: ✅ Skin felt smoother overnight ✅ Pores looked tighter ✅ Subtle glow without irritation ⚠️ Use slowly—this one’s potent! Perfect for oily, dull, or uneven skin. Not ideal for sensitive or reactive types. Worth it if you want real results—fast. 💡 Use at night, 2–3x/week. Always pair with SPF the next morning!

Definitely recommend
I have absolutely loved using this serum, this serum is formulated with only 7 ingredients, this serum helps to minimises the appearance of pores this serum also helps the skin to glow. This serum is suitable for sensitive skin and has a vegan formula. This serum has helped improve my skin texture, my skin is a lot more smoother, I love the packaging, the packaging can be recycled I would definitely repurchase.

If ur skin is stubborn try two layers
I use this serum to exfoliate my skin and also Sunday Riley skin good genes and I feel I can tell the difference in my pores and evened out skin tone. I usually drop two layers of glycolic acid serum and I get better results w it.

This serum, with 9.8% glycolic acid and only 7 ing
I love Kiehl's products, and a consultant recommended I try this one. The serum is formulated with only 7 ingredients, including 9.8% glycolic acid, ensuring a simple yet effective skincare solution. I immediately felt a gentle polishing effect during the first application. The serum absorbs quickly into the skin without any stickiness and has a neutral scent. After a few weeks, my skin feels noticeably firmer. Highly recommend! The packaging is minimalistic and user-friendly, featuring a precise dropper for easy application.

Hello! Our Ultra Pure High-Potency 9.8% Glycolic Acid Serum is a great choice for boosting your skin's glow and minimizing pores. Since it's a potent formula, we recommend starting with 2-3 applications per week in the evening, using just 2-3 drops on clean, dry skin. As your skin adjusts, you can gradually increase how often you use it. If you'd like extra hydration, try layering it with our Hyaluronic Acid serum, or for oil reduction and soothing, our Niacinamide serum works wonders. For more helpful tips and information, check out our website or the product packaging. We're excited for you to experience the benefits!

High quality serum
[This review was collected as part of a promotion.] High quality serum. If you have any open acne it does burn a bit when on but overall makes my skin look great!

Love this
I love Kiehl's products, and this one did not disappoint ! I use a lot of skincare, so I don't buy the same things unless I really like the product. I have repurchased this item and will continue to do so until they pull it. It puts other glycolic acids to shame. It absorbs easily, and I noticed a difference in texture after a few weeks. I use it in my PM routine after my toner and essence. It lasts a long time, so the price isn't that bad when you think about how long it lasts.

Effective product
Just when you didn't think you needed another Kiehl's product... This is great, especially overnight or first thing in the morning. I use a week at a time and then rotate with other Kiehl's serum.

Works well
High potency and works as this product should. Use a little and it helps with cell turnover. Would recommend as long as you’re layering the product

I had a small rough area near my nose. After using this serum it cleared within 1 week. I use this serum at night. My skin has improved a lot since using this serum. Its a 5 Stars for me!

Ouch!
I bought this product a month ago and have been using a small amount nightly. Unfortunately with the warmer temps and sun my face began having a burn reaction. It created large red blotches on my cheeks and below my eyes that are very painful. It seems like a mixture of a chemical burn and sun burn. I didn’t think this would be a problem since I have only been applying the product at night. I’m pretty bummed because I wanted to love this product but unfortunately will not be able to keep it.
