I like the texture and the packaging. The droplet is sanitary and easy to use. I had high hopes for this as I wanted a vitamin C serum, but it made me break out in an allergic reaction.
I've only tried one other vitamin c serum and I much prefer this one. The Klairs one never fully absorbed and I always felt oily...I don't use this consistently so I can't speak to what it can do, but I do think it softens and brightens my skin.
