This serum works wonderfully and has a lovely scent. I am not in a position to analyze the chemical composition so I have no idea what is actually in the bottle, but from what I've seen the results seem positive and I am happy with my purchase. The bottle is of high quality and the dropper is convenient. It doesn't clog my pores or cause irritation. I already see a significant improvement in my skin. I have sensitive skin and this product does not dry me out at all.
