Not for sensitive skin ...
Upon receiving this complimentary product, I was super excited to finally get a chance to try a Kiehl's brand product. The Kiehl's Ultra-Pure High Potency Serum 9.8% Glycolic Acid arrived in a semi-sturdy red and white branded package with black lettering. The serum is enclosed in a small glass bott...

This kiehls high potency glycolic acid is sooo gentle compared to the ones I have used before. Normally they are very harsh on my skin and it doesn't respond well but that wasn't the case with this. It worked well and my skin has looked better since. I don't get worried about using it because it isn't irritating my skin.
Such an amazing product!

I absolutely loved this product. It goes on so nicely and doesn't leave my skin feeling oily. It has a pleasant smell unlike some face serums. After only a few days used I noticed a difference in my skin. It made it appear so much smoother and healthier. I would recommend to anyone looking for a new serum
Wow!
