Discover why higher percentages of niacinamide are not always better for your face, and learn how to balance barrier repair with targeted correction for clear, radiant skin.
Key takeaways
- Niacinamide works as a precursor to NAD+ and NADP+ to support cellular energy, barrier repair, and sebum regulation.
- Low concentrations of 1% to 2% are ideal for delicate skin, building essential ceramides and reducing water loss without flushing.
- High concentrations of 10% target stubborn oiliness, enlarged pores, and hyperpigmentation by inhibiting melanosome transfer.
- Applying high-percentage unbuffered serums to compromised skin can trigger redness, stinging, and small inflamed bumps.
- A zonal application approach allows you to treat oily areas with higher doses while protecting delicate zones with gentle formulations.
