Kiehl'sFast Release Wrinkle-Reducing 0.3% Retinol Night Serum, Helps Accelerate Skin Surface Cell Renewal, Improves Fine Lines & Smooths Out Deep Wrinkles, for Youthful Appearance - 0.94 fl oz

Quality products. I use them on a regular basis. So does my wife.

I purchased this for a friend of mine and she loves it.

This is sooo much cheaper than any department store or website. I love this product it’s one step before a prescription strength retinol

Didn’t come premade so extends the potency of the product. Ended up getting a prescription from my dermatologist for better results.

I ordered this night serum before and it was great, then I re-ordered once I noticed it was on sale, but I was sent a different, much cheaper Kiel’s micro dosing serum. It did not have the retinal powder to be mixed but rather was ready-to-use cream (which is sold at $15 only usually). I am not sure it was intentional, but it was certainly deceiving and fishy that they did that.

No visible changes at all!!

It was open unsealed 3/4 of product was in bottle. Threw away.

I like how this product is the most concentrated retinol the Kiehls brand has ever made! However, it did not feel harsh on my skin and I had no sensitivity to it at all. It applies on nicely with a few drops, and sets on the skin overnight. Great for wrinkle reduction and visibly firming skin for a more youthful look!
