Niacinamide explained — the one active that does almost everything

Oil control, barrier repair, pigmentation, pollution defence — niacinamide quietly does it all.

Niacinamide is vitamin B3. Inside your skin it becomes NAD, a coenzyme that powers cellular repair and energy. That single fact explains why it touches so many problems at once.

It repairs the barrier. Niacinamide pushes your skin to make more ceramides — the lipids that lock moisture in and keep irritants out. This is exactly what TDS 400+ hard water and constant cleansing keep stripping away.

It fades pigmentation. It doesn't bleach. It blocks the transfer of melanin from pigment cells to surface cells, so existing dark spots — and the post-inflammatory marks Indian skin scars with so easily — lighten over time. A landmark study showed clear improvement at 5 percent over twelve weeks.

It controls oil. Niacinamide regulates sebum, which matters through the monsoon when humidity sends oil production into overdrive and breakouts spike.

It fights pollution. As an antioxidant, it buffers the oxidative damage PM2.5 inflicts on your skin all day.

How to use it. 5 percent is the sweet spot — higher invites flushing without extra benefit. It's famously easy-going: layer it with vitamin C, bakuchiol, or moisturiser, morning or night. The old fear about mixing it with vitamin C was overblown; they coexist fine.

If you add one well-studied active to a natural routine, niacinamide is the most forgiving and most versatile place to start.
