What Does Niacinamide Do: 5 Niacinamide Benefits

You may have heard about niacinamide – a common skincare ingredient – but what is it, and what does it do, exactly? In this article, we’ll look at the benefits of niacinamide skincare, explore how it can help you and your skin and find out how you can incorporate the vitamin into your skincare routine.  

What is niacinamide? 

Niacinamide is a water-soluble vitamin. You might know it as vitamin B3, while it’s also sometimes called nicotinamide. It works alongside the natural substances that are already in your skin and has anti-ageing properties. It’s found in a variety of foods, from meat and fish to vegetables and eggs, while it’s also used in skincare products.  

Niacinamide benefits: What does niacinamide do?


1. Helps skin retain moisture 

Niacinamide helps the skin grow a lipid barrier, retaining more moisture. While this is beneficial for all skin types, it’s particularly helpful for people with mature skin or eczema.  

2. Minimises the appearance of large pores 

Niacinamide helps to keep your skin smooth and moisturised, which can lead to the size of your pores decreasing over time. 

3. Regulates oil production 

As well as retaining moisture, niacinamide helps to regulate the amount of oil produced by your sebaceous glands, making sure they don’t produce too much and give you oily skin. 

4. Helps to reduce the appearance of fine lines 

Another benefit of niacinamide is that it can reduce signs of ageing like fine lines and wrinkles, when used over a longer period of time. 

5. Helps build keratin in the skin 

Keratin is a protein that helps to keep skin, hair, and nails strong and healthy. While our bodies produce keratin naturally, niacinamide helps to build it up. As we age, our bodies tend to produce less keratin, making niacinamide a valuable ingredient in anti-ageing skincare products. 

How to use niacinamide 


Fortunately, if you’re wondering how to use niacinamide, it’s simple. You’ll find it in a range of skincare products alongside other helpful ingredients. You can apply leave-on products to cleansed skin or try treatments that target particular skin concerns like large pores or bumps.  

There are niacinamide products that specifically target the eyes too. These products can help address circles under the eye, loss of firmness, and crow’s feet. 

While it can vary from product to product, you might expect to see results from two to four weeks after using niacinamide skincare twice a day, but ongoing use is best if you want to see continued improvement.  

Niacinamide in face serums 

Renergie H.C.F. Triple Serum

Rénergie H.C.F. Triple Serum

Old price New price €125.00

If you’re looking for a niacinamide serum, our Rénergie H.C.F. Triple Serum is ideal. This triple active serum contains not only niacinamide but also hyaluronic acid, vitamin C and ferulic acid for a powerful dose of anti-ageing treatment that targets firmness, wrinkles, and dark spots.  

Vitamin C is often used in anti-ageing skincare products, as it reduces the appearance of wrinkles, while hyaluronic acid is adept at retaining moisture. Ferulic acid is an antioxidant that neutralises free radicals and reduces the formation of wrinkles and fine lines.  

Use the lightweight, fast-absorbing, and smooth serum both morning and night, dispensing two pumps into your palm or onto your fingertips, and mix. Apply on your face and neck using outward and upwards motions, before following with your usual moisturiser and eye cream.  

Each of the three formulas – hyaluronic acid, vitamin C and niacinamide, and ferulic acid – have their own chamber, and with each pump they’re freshly mixed together. This offers more potency and stability than if they were all formulated together in just one chamber.


• Can you use niacinamide with retinol? 

It’s safe to use niacinamide with retinol, and the combination can benefit your skin. Retinol is a form of retinoid, derived from vitamin A. As it’s so effective, it’s a common ingredient in many skincare products. 

• Can you use azelaic acid with niacinamide?  

You can use niacinamide with azelaic acid – they work together to smooth your skin’s texture and reduce the appearance of large pores. 

• Can you use salicylic acid and niacinamide together? 

You can use salicylic acid and niacinamide together, and as a result you might see them listed as ingredients in the same skincare product.  

• Can you use niacinamide with vitamin C?  

Vitamin C and niacinamide work well together, forming one of the three formulas in our Rénergie H.C.F. Triple Serum
