Niacinamide

Also known as: Vitamin B3, Nicotinamide

Generally SafeactiveEWG: 1-2

A multi-tasking Vitamin B3 active that minimises pores, regulates sebum, fades dark spots, and strengthens the barrier.

How it works

Niacinamide works through multiple pathways: it inhibits transfer of melanosomes from melanocytes to keratinocytes (reducing pigmentation), upregulates ceramide synthesis (strengthening the barrier), reduces sebum production, and has anti-inflammatory effects via inhibition of TNF-α. It also supports collagen and keratin synthesis at higher concentrations.

Concentration note

2–5% for most benefits. 10% for advanced sebum control and pore minimisation. Higher concentrations can cause flushing in some individuals.

Safety & restrictions

Very low safety concern. At very high concentrations (above 10%), can cause temporary skin flushing. Does not react negatively with Vitamin C in modern formulations — this is an outdated myth.
