Review (5/5): Yes, buy it.  Just buy it.  C'MON...
I really like this - I bought this on a whim after looking at the ingredients. I've used PLANT OA and Herbivore Face Elixir and several other various Vitamin C serums. I prefer oils to lotions since the method of absorption is much more efficient and it makes my skin look and feel better. So anyway:
I was apprehensive at buying this since it's half the size and all the cost of the other face oils I've tried. But I really wanted to try a new one with different ingredients. So I splurged.
The packaging is quite nice...but I threw it out anyway. The product itself was separated due to freezing in transit. I just left it out at room temperature for a day and then shook it like a maniac before trying it. The first thing I noticed was the smell. It was a bit fruity (but pungent) and reminiscent of green tea. The application was nice and it didn't flood down my face into my eyes like the Herbivore sometimes did if I over-applied. The results are great and my skin looks fantastic. I just complimented myself, which is weird. Do I thank myself?
The only issue I had with the product is the black plastic on the inside holding the dropper must have froze and cracked since I get chunks of black plastic in my product and have to scrape it off.
Overall, quite expensive, but it will last quite a while and the product is definitely worth the money so far.
