What it is

Niacinamide is a water-soluble form of vitamin B3 found naturally in many foods. In skincare, it functions as a multitasking active that works across several skin concerns simultaneously.

How it works

It inhibits the transfer of melanin to skin cells (reducing dark spots), regulates sebum production, strengthens the lipid barrier by increasing ceramide synthesis, and has mild anti-inflammatory properties.

Best for

  • Oily or acne-prone skin types
  • Visible pores or uneven texture
  • Post-inflammatory hyperpigmentation
  • Beginners — well-tolerated at most concentrations

Use with caution if

  • Very high concentrations (>10%) may cause temporary flushing in sensitive individuals
  • Confirmed niacinamide allergy (rare)

Layering notes

Pairs well with almost everything — retinol, vitamin C, AHAs, BHAs. Apply after water-based serums, before heavier creams. No significant interaction concerns at typical concentrations (2–10%).
