A key player in my routine

[This review was collected as part of a promotion.] I LOVE THIS product. It feels lightweight, absorbs nicely, and leaves my skin feeling hydrated without being sticky or heavy. I especially have noticed the sun spot beginning to disappear. It's dried relatively fast, to apply it, I just use the droplet it comes with. It layers well with the rest of my skincare and hasn't caused any irritation or breakouts for me. I'm looking forward to seeing the longer term results with continued use. Oh the 2 bottles were a steal!

Hi glowing skin!

[This review was collected as part of a promotion.] I've been using this for a few weeks now and I'm honestly so impressed. My skin is pretty sensitive, so I was a bit nervous, but it hasn't caused any irritation or redness at all. It's super gentle, sinks in nicely, and has definitely made my skin look brighter and more awake. So glad I added this to my routine!
