Did not work for me
I've been trying to find a good vitaminc c cream/serum to include in my routine and this was sadly not it.
I used for a few days and noticed a ton of new breakouts. This was the only new product I was using, so I stopped it and the breakouts stopped.
Product-wise, it feels nice on the skin, doesn't have a strong scent, and it absorbes really nice.
I like but don't love this serum. It feels nice on the skin, but I haven't noticed any big changes in the overall appearance of my skin with it. I'd give it four stars but they recently changed the packaging from an easy to use metal tube to a plastic tube with a funky lid that's hard to unscrew without taking the whole thing off and exposing the product to air unnecessarily.
