Introduction
Niacinamide might be the most versatile skincare ingredient out there—and it becomes even more valuable in winter. From soothing irritation to strengthening your skin barrier, here’s why niacinamide deserves a spot in your cold-weather routine.
What Is Niacinamide and What Does It Do?
Also known as vitamin B3, niacinamide improves skin texture, balances oil production, reduces redness, and reinforces the skin barrier. It’s ideal for all skin types—even sensitive or acne-prone.
Why It’s Great for Winter
- Strengthens a weakened barrier
- Calms inflammation from cold, dry air
- Helps retain moisture when paired with hydrators like hyaluronic acid
- Reduces sensitivity and blotchiness
Best Concentrations for Beginners
Start with 2–5% formulations if you’re new to niacinamide. Up to 10% can be effective, but may be too strong for sensitive skin.
How to Incorporate It into Your Routine
- Apply after cleansing, before heavier serums or moisturizers
- Can be used morning and night
- Works well with HA, ceramides, peptides, and SPF
Top Tip
Avoid pairing with strong acids in the same routine if your skin is reactive—alternate instead.
