What Is niacinamide?
Niacinamide is a water-soluble form of vitamin B3 that works as an active ingredient in skincare products. It's a stable, non-acidic compound that doesn't degrade when exposed to light or air, making it easy to formulate into various products.
Niacinamide can be derived from natural sources or synthesized in a lab. It's the same active form of vitamin B3 that your body uses naturally.
Niacinamide is a vitamin-based active ingredient that functions as an antioxidant and anti-inflammatory agent in skincare.
Main Benefits
- may help reduce the appearance of enlarged pores
- often used for controlling excess oil production
- commonly recommended for improving skin texture and tone
- may help strengthen the skin barrier
- often used to reduce redness and inflammation
- commonly recommended for minimizing fine lines and wrinkles
How niacinamide Works
Niacinamide works by supporting the skin's natural barrier function and reducing inflammation. It helps regulate sebum production by normalizing oil gland activity, which can minimize pore appearance. The ingredient also supports ceramide production, which strengthens the skin barrier and improves moisture retention. Additionally, niacinamide has antioxidant properties that help protect against environmental damage.
Who Should Use It
- Oily and combination skin types looking to control shine
- Those with enlarged pores or rough texture
- People dealing with redness or sensitivity
- Anyone wanting to strengthen their skin barrier
- Those looking for a gentle, non-irritating active ingredient
Who Should Avoid It
- Those with known allergies to niacinamide (rare)
- People experiencing active irritation or broken skin
- Those using very high concentrations (10%+) should introduce slowly
Can You Mix niacinamide With Other Ingredients?
Yes, niacinamide is highly compatible with most other skincare ingredients. It's one of the easiest actives to layer because it's non-acidic and generally non-irritating. You can safely use it with most other ingredients in your routine.
Compatible ingredients:
- Hyaluronic acid
- Vitamin C (ascorbic acid)
- Retinol and retinoids
- AHA/BHA acids (glycolic, salicylic)

Avoid mixing with:

How to Use It in a Routine
Apply niacinamide in the morning or evening, or both. Use it after cleansing and toning, but before heavier creams. Start with a concentration of 5% and work up to 10% if needed. It can be used daily, and most people tolerate it well. Layer it under moisturizer and sunscreen during the day.
