Isntree's Hyper Niacinamide 20 Serum pushes to 20%, which is an aggressive concentration designed for users with persistent pigmentation, enlarged pores, or texture concerns that haven't responded to lower-dose niacinamide. It's not a beginner product.\u003c\/p\u003e\n\n\u003cp\u003eAt $16.79 for 20ml, the per-ml price is reasonable given the concentration. The small bottle size suggests use as a targeted treatment rather than whole-face daily spread.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\n\u003cp\u003e20% niacinamide addresses pigmentation, oil regulation, pore appearance, and barrier support. At this concentration, results are faster and more dramatic than 5 to 10% formulations, but irritation risk is higher.
