I've been using this product for 28 days as part of Kiehl's 28 day #ChangeYourSkin challenge together with the powerful strength line reducing concentrate. It smells really good and you use a really small amount every night, only 3 drops. The packaging is really different from any product I've used before, it's a small glass bottle with a dropper.

I applied this luxurious product before bed and woke up every morning looking fresh and rested with healthy looking and feeling skin, I've also noticed that blemishes heal and disappear within 3 days, as well as one night I over exfoliated and my skin was right as rain in a couple of days.

It is on the pricey side but for the quality and the fact that it's long lasting it's really worth it. I would recommend this product. I will post an in dept post about the 28 Days as a diary entry during the week!
