Siero Viso Niacinamide 5% B3 Formula Avanzata

My pores look noticeably less visible after about three weeks of nightly use, and the 5% niacinamide hasn’t irritated my sensitive skin at all. It sinks in fast with no sticky residue, which is exactly what I wanted in a daily serum.

I’ve been using this every morning for about a month now, and my skin just looks calmer and more even—the 5% niacinamide really does its thing without any irritation. Even my pores seem less noticeable, which I didn’t expect from a serum this lightweight.

Three weeks in and my pores definitely look less noticeable around my nose, the 5% niacinamide is strong enough to actually see a difference but my skin never got irritated. It sinks in fast with no sticky residue, which is the main reason I've stuck with it this long.
