Creamy Eye Treatment with Avocado by Kiehl's
I use it because I like to moisturize my under eyes, which can get a tad bit dry. Also, I am all about preventing wrinkles as early as possible. Given my current age and about of wrinkles, I can't attest to how well it's preventing or helping with the wrinkles.

Midnight Recovery Concentrate by Kiehl's
The main reason I'm using this oil is for moisture. I would consider my face to be oily, but I find that using tretinoin can dry my skin quite a bit and then my face produces more oil. In the morning, it also feels like my face is smoother and plumper.
