Niacinamide is one of the most widely used ingredients in modern skincare. It appears in serums, moisturizers, toners and treatment formulas because it can support several cosmetic goals without requiring a complicated routine.
What is niacinamide?
Niacinamide is a form of vitamin B3 used in cosmetic skincare. It is water-soluble and can be incorporated into a wide variety of formulas.
Why is niacinamide popular?
Niacinamide is commonly used in formulas designed to support:
- The skin barrier
- More even-looking tone
- Improved appearance of enlarged pores
- Oil-balance routines
- Overall skin conditioning
Does a higher percentage work better?
Not necessarily. High percentage claims can look impressive on packaging, but more is not automatically better. A lower percentage in a well-designed formula may be easier to tolerate and still fit the intended cosmetic use.
Who may benefit from niacinamide?
Niacinamide is used across many skin types, including routines for combination, oily, dry and sensitive-feeling skin. Suitability still depends on the complete product formula.
How should niacinamide be used?
Follow the directions for the specific product. Niacinamide can appear in multiple routine steps, so there is usually no need to use a niacinamide toner, serum and moisturizer all at once.
Can niacinamide be used with vitamin C?
Modern cosmetic formulations can generally include niacinamide and vitamin C in the same routine. The old idea that they should never be combined is overly broad. Tolerance and formula compatibility are more important than a blanket rule.
Can niacinamide be used with retinoids?
Yes, these ingredient categories are commonly used in the same overall routine. A moisturizer or serum containing niacinamide can help keep a retinoid routine simple and hydration-focused.
Niacinamide and the skin barrier
Niacinamide is often included in barrier-support formulas. If your main goal is reducing the complexity of a stressed-skin routine, see our Skin Barrier Guide.
