About USP-S | Serum
The USP-S | Serum in Factory New is the classified USP-S with the orange-and-dark biological-aesthetic illustration at FN — refined laboratory-aesthetic design referencing chemical-serum imagery across the slide.
Why FN matters on Serum
The Serum design depends on the orange-and-dark colour relationships and the fine biological-pattern detail. FN preserves both at peak clarity. The USP-S slide gives the design generous visible canvas.
