What it is
Niacinamide is a cosmetic form of vitamin B3 used in serums, creams and toners. It is not a medical treatment; in beauty routines it is usually chosen for a comfortable-looking barrier and a more balanced-looking finish.
How to use it
Choose one leave-on product and apply a thin layer after cleansing. Follow with moisturizer, and use sunscreen in the morning. Sensitive skin should start a few times weekly.
What to avoid
Avoid stacking several high-strength niacinamide products or layering it with too many strong exfoliants on the same day. If skin feels tight, hot or itchy, pause active products and simplify.
Pair it with
- Fragrance-free moisturizer for comfort.
- Gentle cleanser to avoid over-stripping.
- Mineral sunscreen in the morning.
- Simple hydrating toner if the skin tolerates it.
