Ratings & Reviews

Here's what customers think
  • This retinol serum is effective at improving skin texture, reducing the appearance of fine lines and wrinkles, and providing a healthy, glowing complexion without causing significant irritation or dryness for most users.
  • The lightweight, non-greasy formula absorbs easily into the skin, and a little product goes a long way.
  • The inclusion of ceramides and peptides provides additional hydration and anti-aging benefits.
  • While a few users with very sensitive skin experienced some initial irritation, the retinol concentration is generally well-tolerated, especially when introduced gradually.

Gentle Retinol

I love this serum. It is gentle enough to use everyday with visible results. I would not want to be without it … ever!

Package design not good

I love the product but the packaging can be approved. There is no way to tell how much product is left in the bottle. I took it on a trip and ran out. You can’t take the too odd to get inside the bottle. Had I known there was so little left I would have brought another bottle.

Can irritate the skin

I was very cautious about trying this and had a deluxe sample and tried a small amount on my neck. It left my skin dry and flaky, and it took a couple of weeks for it to clam down. I don't even have sensitive skin, so if you do have sensitivities, I would recommend trying it first on a small area of the face. It didn't work for me and I don't think you should let your skin learn to tolerate products either because it can lead to sensitivities.

I was not a believer

I was skeptical about buying this product. Even the first is Rona’s not sure about. However, once I continued use I saw some Maher differences in my skin. Would highly recommend giving this a try!

Incentivized review

Amazing retinol.

The Micro-Dose Anti-Aging Retinol Serum works really well. I love the packaging, which is a vacuum-sealed bag with a glass bottle; it feels heavy and luxurious, which gives me peace of mind. Two pumps are just enough for my face, and it’s really helping with my acne marks and tiny lines. It does take a bit longer to see results due to the lower concentration—I heard it’s 0.1% retinol, compared to 0.2% in other brands. I also don’t love that Kiehl’s didn’t list the concentration; I had to hunt for it. On the bright side, it makes it more usable and beginner-friendly. I started using it four days a week, and it worked well and never caused dryness or problems. Definitely the best retinol I’ve tried!
