What Is Niacinamide and What Does It Do for the Skin?

Niacinamide has become one of the most talked about ingredients in modern skincare—and for good reason.

While niacinamide is great for our skin year-round, seasonally it can support dry and flaky skin going into the colder seasons.

Here’s how it works and why it has made its way into some of our favorite clean and effective skincare formulas.

What is niacinamide?

Niacinamide is a type of vitamin B3 that plays an essential role in maintaining healthy skin, brain function, and energy metabolism.

There are several forms of vitamin B3, with niacinamide being particularly beneficial in skincare, such as for treating acne and hyperpigmentation.

As a water-soluble nutrient, it must be regularly consumed through protein-rich foods like fish, chicken, and eggs, as well as cereals, seeds, and beans, or through supplements, since it isn’t stored in the body.

While the body has limited ability to synthesize it from the amino acid tryptophan, including it in your diet is important to support your skin’s vitality, alongside using topical forms of niacinamide to tackle skin concerns directly, such as creams and serums.

Among the variants of vitamin B3, including nicotinic acid and nicotinamide riboside, niacinamide stands out as the best derivative for skin health and hydration, and that’s why you can find it in lots of Beauty Heroes’ products, which we will outline below.

What does niacinamide do?

Niacinamide and nicotinamide are the same molecule, but the name most often used in a biological context is nicotinamide, and it is cited as helping the body convert food into energy and supporting DNA repair and cell health.

In skincare and dermatology, niacinamide is valued for its ability to address acne and calm the feelings and appearance of inflammation, balance oil production, minimize the appearance of pores, fade the appearance of dark spots, and strengthen the skin’s barrier.

To put it into more detail:

Topical niacinamide offers multiple benefits for skin health, like enhancing moisture retention and protecting the skin’s barrier by boosting ceramide production.

Studies indicate that it strengthens the protective outer layer of skin, which is essential across all skin types for locking in hydration while helping to block free radicals and irritants.

By supporting the skin’s natural barrier and regulating sebaceous gland activity, niacinamide also balances the experience of oil production and prevents excess sebum without stripping or drying the skin. This helps to reduce the appearance of shine, minimize the appearance of pores, and develop a more even-looking complexion over time.

Niacinamide also possesses soothing and antioxidant qualities, which can help address the sensations of inflammation, appearance of redness, and some experience benefits for acne.

For mature skin, it helps with fading the appearance of dark spots and reducing the appearance of hyperpigmentation by inhibiting the transfer of melanin-filled cells to the upper layers of the skin. Because of this, along with its moisturizing properties, it tends to be used in a lot of well-aging products to reduce the appearance of fine lines, wrinkles, and uneven skin tone.

What is niacinamide good for?

Skincare products often feature niacinamide due to its ability to brighten and hydrate the skin. Incorporating it into your daily regimen can lead to skin that looks smoother, softer, and more luminous.

Ongoing research suggests that niacinamide can help regulate sebum levels, making it particularly valuable for individuals dealing with oily skin and congestion.

Additionally, niacinamide's antioxidant properties may enable it to neutralize free radicals, the culprits behind common aging signs like fine lines, dullness, and sun spots.

These same antioxidant and hydrating benefits also work to soothe irritated skin and diminish the appearance of redness and hyperpigmentation.

Is niacinamide good for all skin types?

Luckily for you, it’s gentle and effective for most skin types, including sensitive, oily, and acne-prone skin, and has been formulated into serums and moisturizers, so you can benefit from all the skin-perfecting properties niacinamide has to offer.

How long does it take to see results?

You can start seeing results from niacinamide in as little as 1-2 weeks; it will initially improve hydration and oiliness. However, for more significant and visible changes like reduced dark spots, a smoother texture, and less visible pores, it typically takes 8-12 weeks of consistent use.

Within the first few weeks of use, you may notice your skin feels more hydrated and looks less oily relatively quickly. Some users also see a decrease in redness during this timeframe, and many people experience a significant decrease in acne and breakouts.

With continued use (about 8-12 weeks), you should notice smaller, less visible pores. Hyperpigmentation, dark spots, and sun spots become less noticeable, while your skin will feel and look smoother and more refined. Fine lines and wrinkles may also appear visibly reduced.

Using the product consistently, ideally twice daily, is crucial for seeing the best results. Products with a higher percentage of niacinamide may show effects faster, though 5-10% is generally considered effective with a lower risk of irritation. The severity and type of your skin concerns can affect the timeline, and using niacinamide as part of a complete skincare routine, including a broad-spectrum sunscreen, can enhance the results.

Is niacinamide the perfect serum for you?

If you have excess sebum, hyperpigmentation, or fine lines, yes.

Niacinamide is a true multitasker—brightening dull skin, strengthening your natural barrier, balancing oil, and treating acne—all while promoting a smooth, radiant complexion.
