What Does Niacinamide Do? Niacinamide Benefits for Skin

With all the different active ingredients, antioxidants, vitamins, and nutrients out there, it can be hard to keep up with all the different ingredients that make up your skincare. If you can’t even keep track of them, how do you know which ones are worth your time? 

We’re here to make it easier for you, at least when it comes to one skincare ingredient: niacinamide. 

Niacinamide is one of the most popular topical ingredients out there. It’s used in skincare products ranging from cleansers and exfoliants to eye creams and moisturizers. Not every ingredient can boast this kind of versatility. The reason why niacinamide is a part of so many different types of products is because it really does work. 

Today, we’ll break down this skincare ingredient, explaining how niacinamide benefits your skin and how you can add those benefits to your own skincare routine.

What Is Niacinamide?

Niacinamide is a form of vitamin B — vitamin B3, to be exact. This vitamin itself is actually called niacin, with niacinamide being only one type of niacin. Other types of niacin include nicotinamide, nicotinic acid, and inositol hexaniacinate. 

As a vitamin, all the different variants of niacin work together to help your body produce energy from good, create various hormones, and support your nervous and cardiovascular systems. While niacinamide plays a part in these larger processes, its real function in your body happens in your skin. 

How Does Niacinamide Work?

Different from other types of niacin, niacinamide supports your skin health. Instead of being ingested through food, topical niacinamides are absorbed directly through your skin

This provides two main benefits: 

  1. Topical niacinamides can reach your skin cells faster, targeting the exact area of the body the skincare ingredient is made to support. 
  1. Topical niacinamides can be made in higher concentrations, balancing out its limitations as a water-soluble vitamin and creating real results for your skin.

What Are the Benefits of Niacinamide for Your Skin?

Niacinamide is what dermatologists call a multi-purpose skincare ingredient. Unlike other products that serve only one purpose in your skincare routine, niacinamide works to support your skin in more ways than one . That’s why it can be found in so many skincare products: it has multiple benefits for your skin. 


One of the largest benefits of niacinamide — and what makes it a popular skincare ingredient, especially for those with dry skin — is its ability to hydrate the skin. 

Niacinamide works to reduce the amount of water that evaporates through your skin through a process called transepidermal water loss , or TEWL. While this water loss is completely natural, it’s not always great for your skin. 

“Moisture is crucial for supporting the skin’s health and appearance,” notes Melinda Hany, Registered Nurse. Without enough water, your skin can start to feel itchy, become red, or even flake off in places. This kind of dryness can also speed up signs of aging — making niacinamide an anti-aging skincare product, as it keeps the skin nourished and can prevent that kind of dryness. 

Supports Even Skin Tone 

Niacinamides can also even out your skin tone by working directly against the cause of hyperpigmentation: melanin transfer. 

Hyperpigmentation is a skin condition caused by an increase of melanin in the skin — which Hany notes are also known as “dark spots.” If left to complete the process, this darker pigment would push up from melanocytes deep within the skin until they reach the surface, where the pigment is visible through the skin barrier. 

But niacinamide interrupts this process , preventing the pigment from traveling up through the skin. If the pigment can’t reach the skin’s surface, it can’t cause hyperpigmentation. 

Promotes Radiance

Not only does preventing this kind of hyperpigmentation even out your skin tone, but this particular effect of niacinamide also leaves you with radiant skin. 

Without the dark spots and discoloration caused by hyperpigmentation, you’re left with an even complexion that is consistent from chin to forehead. Combine this with the hydrating effects of niacinamide, which keeps your skin smooth and supple no matter your skin type, from sensitive skin to acne-prone skin and more.

Helps Minimize the Appearance of Fine Lines

Another benefit of this skincare ingredient is the anti-aging effects of niacinamide. 

Niacinamide works to keep the skin hydrated, which can prevent early signs of aging. Additionally, this vitamin also minimizes signs of aging by reducing the appearance of fine lines on the skin. 

Niacinamide can encourage your skin to make more collagen — a powerful protein that provides structure and support to the different layers of your skin. Without collagen, your skin can become loose and struggle to bounce back, making it prone to wrinkles and fine lines. By helping your skin continue to produce collagen, niacinamide combats these signs of aging. 

Supports a Healthy Skin Barrier

But niacinamide doesn’t just support your skin through its own qualities as a B vitamin. It also supports the other nutrients in your skin. 

Some studies have shown that niacinamide actually increases your body’s production of ceramides and keratin , two key structures in your skin: 

  • Ceramides are a type of lipid in your skin that make up about 50% of your skin’s outer layer.
  • Keratin is a type of protein that protects your skin’s outer epithelial cells and helps keep your skin flexible. 

The more ceramides and keratin that are present, the stronger your skin barrier will be. By supporting these key structures, niacinamide works to strengthen your skin from the inside out. 

Helps Support Balanced Sebum Production

Alongside ceramides and keratin, niacinamide also helps your skin produce another essential building block for your skin barrier: sebum. 

Sebum is a type of oil produced by your sebaceous glands that helps lubricate your skin and lock in your skin’s natural moisture. Everybody needs sebum, whether you have oily skin or dry skin, because it is the driving force behind keeping your skin barrier strong. Niacinamide works to protect your skin by promoting regular sebum production in your skin. 

How Can You Incorporate Niacinamide Into Your Routine?

From its hydrating side effects to how it supports other important components of your skin, niacinamide is one powerhouse of a skincare ingredient. Plus, because its benefits are so vast, it makes its way into so many different kinds of skincare products.
