Very impressed with the results!
I received the full sized 0.68 oz/20 ml bottle as a part of an Advent calendar I purchased and am pleased with having used it for only a few weeks. This is a slippery, velvety fluid which can be mixed with your favorite moisturizer or applied directly to your skin. I have been mixing it with Augustinus Bader The Rich Cream as the last step of my nightly skin routine.
The Good... This was my first 111Skin product and I was doubtful; however, I really feel it has made a noticeable difference by brightening up my face and evening out my skin tone.
The Bad... While I am impressed with the results, this Vitamin C serum is a little on the spendy side (retailing for $155 for the 0.68 oz) so I will seriously have to consider if I absolutely need to repurchase when it runs out.
Final thoughts... If cost is not a consideration for you, this really is a fantastic product which will work relatively quickly to balance any discolouration you have and fade areas of hyperpigmentation to give you a noticeably radiant, more even complexion.
