The appearance of the liquid is good, and it's a completely ordinary serum! However, it's a product I'd be hard-pressed to live without in the winter. When I first bought it to try it out and applied it, I didn't notice any irritation, nor did I notice any scent, so I wondered if it really worked and what was so good about it. However, the more I continued to use it, the more noticeable the results became. My skin became deeply moisturized and supple! Best of all, I personally rate it highly as the best thing about it because it doesn't irritate me at all.
