Niacinamide has become one of the most sought-after skincare ingredients in recent years. You'll find it in serums, moisturisers and toners, and it's commonly recommended for a wide range of skin types. Its popularity is largely due to its versatility – it may help with excess oil production, the appearance of enlarged pores, uneven skin tone and supporting the skin barrier.
Unlike some active ingredients, niacinamide is often well tolerated even by sensitive skin, making it a popular addition to everyday skincare routines.
But what exactly is niacinamide, how does it work, and who is it suitable for?
Niacinamide, also known as vitamin B3, is a water-soluble form of vitamin B3. In skincare, it is valued for its wide range of beneficial effects on the skin.
It is considered an ingredient that supports the skin's natural functions and helps maintain its balance. This is one of the reasons why it has become a staple in both modern cosmetics and Korean skincare.
Niacinamide can be found in products formulated for oily, dry, sensitive and mature skin.
Niacinamide is regarded as one of the most versatile skincare ingredients. Its effects may vary depending on the concentration and formulation of the product.
Some of its most commonly recognised benefits include:
This combination of benefits explains why niacinamide is suitable for so many different skin types.
One of niacinamide's key benefits is its ability to support the skin's natural protective barrier.
The skin barrier helps retain moisture while protecting the skin from external aggressors. When it becomes compromised, you may experience tightness, increased sensitivity or irritation.
For this reason, niacinamide is commonly included in products designed to support a healthy skin barrier and is often paired with ceramides or panthenol.
Oily and combination skin are among the skin types that often benefit from niacinamide.
Some studies suggest that niacinamide may help regulate sebum production and improve the overall appearance of the skin. As a result, it is frequently included in products formulated for blemish-prone skin.
However, it's important to remember that everyone's skin is different, and results can vary from person to person.
Pores cannot be permanently shrunk, as their size is largely determined by genetics.
However, niacinamide may help improve the overall appearance of the skin and make enlarged pores appear less noticeable. This is mainly due to its ability to help regulate oil production and support a healthy skin barrier.
That's why niacinamide is often recommended for skin prone to excess shine and visible pores.
In most cases, yes.
Niacinamide is generally considered to be well tolerated and is commonly found in products formulated for sensitive skin.
That said, more sensitive skin may react to higher concentrations of active ingredients. If you're new to niacinamide, it may be best to start with a lower concentration and monitor how your skin responds.
As with any skincare ingredient, every skin type reacts differently.
Products containing niacinamide are available in a range of concentrations, most commonly between 2% and 10%.
Lower concentrations are often perfectly sufficient for everyday skincare. Higher concentrations do not necessarily deliver better results and may increase the risk of irritation for some people.
When choosing a product, it's worth considering not only the percentage of niacinamide but also the overall formulation.
One of niacinamide's greatest strengths is its compatibility with many other active ingredients.
It is commonly combined with:
In the past, there were concerns about combining niacinamide with vitamin C. However, current evidence suggests that modern cosmetic formulations allow these ingredients to work well together.
As always, it's important to pay attention to how your own skin responds.
Niacinamide is commonly found in serums, toners and moisturisers, and it can be used both morning and evening.
It is typically applied after cleansing and before moisturiser or sunscreen.
A typical morning routine might look like this:
Cleanser → Toner → Niacinamide Serum → Moisturiser → SPF
If you're using several active ingredients, it's generally best to introduce new products gradually.
Good skincare takes time. Some people notice changes within a few weeks, while for others it may take longer.
Results depend not only on the ingredient itself but also on consistent use, your overall skincare routine and your individual skin condition.
In skincare, long-term consistency is usually more important than expecting rapid results.
Niacinamide is one of the most versatile and popular ingredients in modern skincare. Thanks to its broad range of benefits, it can be suitable for oily, sensitive and mature skin, while also pairing well with many other active ingredients.
Whether you're looking to support your skin barrier, achieve a more even complexion or help regulate excess oil, niacinamide can be a valuable addition to your daily skincare routine.
After all, healthy skin is rarely the result of a single miracle ingredient, but rather of a well-balanced and sustainable routine.
