Niacinamide Skincare Guide: The Multitasking Ingredient
This guide provides shopping guidance only—not medical, dermatology, diagnosis, or treatment advice. For health concerns, consult a licensed professional.
What Is Niacinamide?
Niacinamide is a form of vitamin B3 (also called nicotinamide). It's one of the most versatile and well-tolerated skincare ingredients available, making it suitable for nearly every skin type and compatible with most other active ingredients.
Unlike some skincare actives that target one specific concern, niacinamide works on multiple fronts: oil control, barrier support, pore appearance, redness reduction, and evening skin tone. This makes it a "Swiss army knife" ingredient that benefits most routines.
Benefits of Niacinamide
Oil Control
Niacinamide helps regulate sebum production, making it particularly valuable for oily skin types. Studies show it can reduce oiliness without the drying effects of harsh ingredients.
Minimizing Pore Appearance
By reducing oil production and supporting skin elasticity, niacinamide can make pores appear smaller over time. It doesn't actually shrink pores (nothing can) but helps them look less prominent.
Strengthening the Skin Barrier
Niacinamide increases the production of ceramides and other lipids that make up the skin barrier. A stronger barrier means better moisture retention and protection against environmental stressors—especially important for sensitive skin and those with rosacea.
Evening Skin Tone
Niacinamide inhibits the transfer of melanin to skin cells, helping to fade existing dark spots and prevent new ones. It's gentler than many other brightening ingredients. For more on this topic, see our hyperpigmentation guide.
Reducing Redness
Its anti-inflammatory properties help calm redness and irritation. This is why it's often recommended for redness-prone and rosacea-prone skin.
Supporting Anti-Aging
While not primarily an anti-aging ingredient, niacinamide supports collagen production and improves skin elasticity. It pairs well with dedicated anti-aging ingredients. See our anti-aging guide.
Choosing a Niacinamide Product
Concentration
Research shows benefits at 2-5% concentration. Many products contain 5-10%. Higher isn't always better—concentrations above 10% may cause irritation without additional benefit. If you're new to niacinamide, start with 5% or less.
Product Format
- Serums: Most concentrated delivery; absorb quickly
- Toners: Lighter formulas, good for layering
- Moisturizers: Convenient; often combined with other beneficial ingredients
- Multi-ingredient products: Niacinamide often appears alongside hyaluronic acid, zinc, or peptides
How to Use Niacinamide
When to Apply
Niacinamide works both morning and evening. Many people use it twice daily for maximum benefit. It's stable and doesn't increase sun sensitivity, so daytime use is perfectly fine.
Where in Your Routine
Apply after cleansing and toning, before heavier products:
- Cleanser
- Toner (if using)
- Thin serums (vitamin C, if using)
- Niacinamide serum
- Heavier serums (hyaluronic acid, etc.)
- Moisturizer
- Sunscreen (AM)
Layering with Other Ingredients
Niacinamide is extremely compatible with other actives:
Niacinamide + Vitamin C
The old advice that these can't be combined has been debunked. Modern formulations are stable together. Many people use vitamin C in the morning and niacinamide at night, but layering in the same routine is fine. See our vitamin C guide.
Niacinamide + Retinol
An excellent pairing. Niacinamide helps buffer potential retinol irritation and supports the skin barrier while retinol works on cell turnover. See our retinol guide.
Niacinamide + Hyaluronic Acid
Great combination for hydration and barrier support. Both are hydrating and neither causes irritation. See our hyaluronic acid guide.
Niacinamide + AHAs/BHAs
Can be used together, though some prefer to alternate or use at different times of day. Niacinamide's barrier-strengthening properties can help counteract potential irritation from acids.
Niacinamide + Zinc
A popular combination for oily and acne-prone skin. Zinc has additional oil-controlling and antibacterial properties.
For Different Skin Types
Oily Skin
One of the best ingredients for oil control. Look for lightweight, water-based formulas, often combined with zinc.
Dry Skin
The barrier-strengthening benefits help dry skin retain moisture. Pair with hyaluronic acid and rich moisturizers.
Sensitive Skin
Generally very well-tolerated. Start with lower concentrations (2-5%) and patch test. Excellent for calming redness.
Acne-Prone Skin
Helps regulate oil and has anti-inflammatory properties. Look for formulas with zinc. See our acne-prone skincare guide.
Aging Skin
Supports collagen, evens tone, and strengthens the barrier. Pairs beautifully with retinol and peptides.

Frequently Asked Questions
What does niacinamide do for skin?
Niacinamide (vitamin B3) helps regulate oil production, minimize the appearance of pores, strengthen the skin barrier, even out skin tone, and reduce redness. It's well-tolerated by most skin types, including sensitive skin.
What percentage of niacinamide is effective?
Research shows benefits at concentrations of 2-5%. Many products use 5-10%. Higher concentrations (10%+) may cause irritation in some people without additional benefit. Start with 5% or less if you're new to niacinamide.
Can you use niacinamide with vitamin C?
Yes! The old advice to avoid combining them has been debunked. Modern formulations are stable together. Many people use vitamin C in the morning and niacinamide at night, or layer them in the same routine.
Can niacinamide cause breakouts?
Some people report initial breakouts when starting niacinamide, often called purging. This is usually temporary. However, high concentrations (10%+) may cause irritation that looks like breakouts. Try a lower concentration if this occurs.
