Instant glow with skincare benefits
This gives an instant glow without feeling greasy, which is harder to find than you’d think. It works well as both skincare and a makeup base, especially for dull or tired skin. Over time I’ve noticed a subtle brightening effect. The scent is sweet but fades quickly.

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.

Good
I use this every night. I like it and I think I have seen a difference of less bumpy texture however the difference isn't crazy and it's not my favourite serum. However it is not too sticky which I like and I also am a big fan of Kiehls products so would recommend kiehls but not this product.

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.
