Hi, Rossella! You come from alfemminile, right? I think I recognised you... I'm from Italy too. I use SFF with Select Cover-Up concealer and it's the best combo, IMO. Studio Tech is also good, just a little "heavy" if your skin is a bit oily. It all depends if you prefer a liquid or a compact foundation. My advice is to stick to SFF, the best I've ever tried.
