I've heard so much about Vitamin C serums and the amazing things they can do for your skin so I was so happy to finally be able to try it for myself! I've only been using it for half a week, so no miraculous results yet, but there's been no irritation to my skin, which was my biggest fear. There also isn't a strong scent, not even a very citrusy one, which I was slightly afraid of - it's only orange-esque if you put your nose up to the bottle. It's only 30 mls but should probably last a decent amount of time, and you don't want to buy larger amounts anyway since it will oxidise so quickly. I was just really impressed with jolse because the manufacture date on my bottle was just a month before my purchase date, which is very good considering I've heard horror stories about people buying a bottle only to have it oxidize in a week or two because it was manufactured a long time before they purchased! To prevent mine from oxidizing I store it in its original packaging, inside a shoebox where the rest of my cosmetics are organized, inside my closet (since I don't have easy access to store it in a fridge, which would be better).
