This works amazing! I love all their products. Nice finish, coverage. A lot of product and very affordable. Doesn’t really have a scent which I appreciate

I used several glycolic formulas and this serum feels good, absorbs well, and has mad a significant difference in the appearance of my forehead lines.

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.
