I try my best to have a semi-consistent skincare routine so my face does not freak out more than it already does. I love trying new products but I avoid adding new ones to my skincare routine, first, because I like to give products a fair shot before I decide that I won't repurchase or quit using them. Secondly, because my skin can go a bit crazy when I change products. Here are two products I started to use last year, probably around October/November and I'm still really much enjoying.
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.
