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!
