I've tried this serum in the mini size which came into a set and first of all, 8ml last enough for 2 weeks (day and night application) and as you put onto your skin feels a little sticky, but it fades almost straight away. Very light texture, hydrating and great as a base for makeup. I'd totally recommend it (even if I prefer the Ascorbyl tetraisopalmitate solution20% in vitamin F by The Ordinary) also because has a very green Inci! Go Farmacy!
