Niacinamide has become one of the most popular skincare ingredients in recent years, and for good reason. Whether you’re looking to reduce redness, improve your skin barrier, minimise the appearance of pores, or achieve a brighter complexion, niacinamide is a versatile ingredient that suits almost every skin type.
If you’re new to skincare, you may be wondering what niacinamide actually does and whether it’s worth adding to your routine. In this guide, we’ll explore the benefits of niacinamide for skin, how to use it correctly, and some of the best niacinamide serums to consider.
What Is Niacinamide?
Niacinamide, also known as vitamin B3, is a water-soluble vitamin that helps support healthy skin. Unlike stronger active ingredients, niacinamide is generally well tolerated by most skin types, making it a great choice for beginners.
Some of the main niacinamide serum benefits include improving skin hydration, strengthening the skin barrier, reducing redness, balancing excess oil, and creating a smoother, brighter complexion.
Benefits of Niacinamide for Skin
There are many reasons why niacinamide has become a staple ingredient in modern skincare routines.
Helps Strengthen the Skin Barrier
One of the biggest benefits of niacinamide is its ability to support the skin barrier. A healthy skin barrier helps retain moisture while protecting your skin from environmental damage and irritation.
Reduces the Appearance of Pores
Although niacinamide doesn’t physically shrink pores, it can help minimise their appearance by regulating excess oil production and improving skin texture.
Balances Oily Skin
Niacinamide is an excellent ingredient for people with oily or combination skin because it helps regulate sebum production without over-drying the skin.
Brightens Uneven Skin Tone
Regular use of niacinamide may help improve the appearance of uneven skin tone and dullness, leaving your complexion looking healthier and more radiant.
Helps Calm Redness
Many people with sensitive or easily irritated skin find niacinamide beneficial because of its soothing and anti-inflammatory properties.
Can You Use Niacinamide with Vitamin C?
A common skincare question is, “Can I use niacinamide with vitamin C?”
The answer is yes. Older advice suggested these ingredients shouldn’t be used together, but modern formulations show they work well in the same skincare routine.
Vitamin C helps brighten the skin and protect against environmental damage, while niacinamide supports the skin barrier and helps balance oil production. Together, they can complement each other and contribute to a healthier-looking complexion.
If you’re introducing both ingredients for the first time, start slowly and monitor how your skin responds.
How to Use Niacinamide
Adding niacinamide to your skincare routine is simple.
A typical routine looks like this:
Morning
- Cleanser
- Vitamin C serum (optional)
- Niacinamide serum
- Moisturiser
- Sunscreen
Evening
- Cleanser
- Niacinamide serum
- Moisturiser
Niacinamide is gentle enough for daily use and can be used morning, evening, or both depending on your skincare routine.

Common Niacinamide Mistakes
Using Too Many Active Ingredients at Once
Although niacinamide is generally gentle, introducing several new active ingredients at the same time can make it difficult to identify what’s working or causing irritation. Add new products gradually and give your skin time to adjust.
Expecting Instant Results
Niacinamide isn’t an overnight solution. Most people begin to notice improvements in their skin after several weeks of consistent use.
Skipping Moisturiser
Niacinamide supports the skin barrier, but it works best when paired with a good moisturiser to help lock in hydration.
Forgetting Sunscreen
If you’re targeting pigmentation or uneven skin tone, daily sunscreen is essential to help protect your results and prevent further sun damage.
