Not to oily
It works with layering my skincare products. When I put it on my face it's a bit a oily, but when I pat it on my face it's not oily anymore.

Buying on Repeat
Smells divine citrusy but not overwhelming, it was a love from first use, and I'm dedicated to it as part of my morning routine for two years now. It contains the best type of vit C - stable & lipophilic (it goes through your skin barrier), which is photoprotective with antioxidant properties, boosts collagen production and evens out pigmentation. It didn't give any irritation (but my skin isn't super sensitive). It really helped with my dull skin by brightening it. I like the marriage of science and nature that the company embodies. I even like the fact they are recommending 6 drops, which is about right, and not like the other companies when they say to use 1-2 drops, which are absorbed before you got the chance to apply them. An absolute staple!

Does not work for my skin
I have combination skin and I found it way too oily, broke me out especially in the forehead area. I also found that it is very messy to use, it's oily but somehow very liquid, drips everywhere. It's disappointing, especially at this price point.
