Rated 4 out of 5 by from GREAT SERUM I tried this serum for a few weeks now. Initial thoughts as follows, love the texture, its hydrating and gets absorbed quite quickly. I would be careful about using it on compromised skin barrier as it does contain glycolic acid.

Rated 5 out of 5 by from My skin DRANK this in! I had never tried a product by this brand before I received this and WOW. I am absolutely flabbergasted at how incredible this makes my skin feel. The texture is beautiful and almost transforms when coming out of the pipette in comparison to when absorbed into my skin. My skin genuinely felt like I’d lost gained about 15 years again and I was 25! My make up went on beautifully over the top of this. I’m so so impressed. I will be re-purchasing this for as long as it is on sale in the future. A definite must for your skin

Rated 5 out of 5 by from Great product! I’ve been using Kiehl’s Glycolic Acid Serum for a while now and it’s been great. It’s a really potent product but still gentle enough for regular use. My skin looks much clearer and smoother, and I’ve noticed a big improvement in texture and breakouts. It absorbs well, doesn’t feel sticky, and a little goes a long way. Definitely one of the best exfoliating serums I’ve tried and something I’ll keep repurchasing

Rated 4 out of 5 by from Great Glycolic Serum As someone with combination–oily skin, I’m honestly really impressed. I naturally gravitate towards ingredients like glycolic acid because I love that smooth, glow-boosting effect, and this product fits perfectly into that kind of routine. It feels lightweight on the skin, absorbs nicely without leaving any greasy residue, and helps keep my T-zone looking more balanced while still giving my skin that fresh, refined look. After a few uses, my skin feels smoother and looks a bit brighter, which is exactly what I look for in my skincare.

Rated 5 out of 5 by from My skin looks great! I’ve been using this for the last few weeks and my skin looks so good. The texture of my skin looks more refined essentially around the nose area and I’ve definitely got a bit of a glow which has made me skin looks healthier.
