I also have dark undereyes! D: I recently started using a Vitamin C serum/oil, but I haven't noticed any drastic changes (but also I know I'm not drinking enough water, so that doesn't help). I like it, but once I finish the sample size (I got this one), I might look around for a new one.

Do you find that regularly doing a face mask helps your skin? I just do cleanser + toner + moisturizer, but I feel like I should give my skin some more love. u__u
