Niacinamide, also known as Vitamin B3, is one of dermatology’s most versatile actives — a daily essential that strengthens the barrier, refines pores, and reduces visible redness.

This evidence-based guide explains how niacinamide modulates melanin transfer, boosts ceramide production, and supports long-term clarity. With exact layering steps, do/don’t tables, and timelines, it helps you build a calm, bright, balanced complexion that lasts.
