I received this in a Dermafix box about a year ago. It is the gentlest and most effective serum I have tried (and there have been many). I can't use the really strong serums because they totally destroy my skin barrier. I will be purchasing more. I must admit I have liked everything that has been sent by this brand so far. It is also affordable in the world of Vitamin C serum. If you have sensitive skin and seem to react to other vitamin C products, this might be something to try. Just a head's up, this is not a thin, watery serum. It is more of a light lotion, which maybe enough moisture if you have oily skin.
