Chemical Properties

Chemically, niacinamide is a stable compound that is not affected by light, heat, or oxidizing agents. This stability ensures that niacinamide maintains its efficacy in various formulations, from serums to creams. It penetrates the skin easily, where it performs a host of beneficial actions.

Historical Usage

Historically, niacinamide has been used for its medicinal properties. It was initially recognized for its role in preventing and treating pellagra, a condition caused by niacin (vitamin B3) deficiency, which manifests as dermatitis, diarrhoea, and dementia. Today, its role has expanded into the cosmetic industry, where it is hailed for its transformative effects on the skin.

Benefits of Niacinamide for Skin

Reducing Inflammation

One of the most celebrated benefits of niacinamide is its anti-inflammatory properties. It helps to soothe irritated skin, making it an excellent ingredient for individuals with inflammatory conditions such as acne, rosacea, and eczema. By reducing redness and swelling, niacinamide promotes a calmer, more even-toned complexion.

Minimizing Pores

Enlarged pores can be a significant cosmetic concern for many people. Niacinamide helps to minimize the appearance of pores by regulating sebum production and improving the skin’s overall texture. This results in a smoother, more refined appearance.

Controlling Oil Production

Excess oil production can lead to clogged pores and breakouts. Niacinamide effectively controls sebum production, which helps to prevent the formation of acne. This makes it particularly beneficial for individuals with oily or combination skinOpens in a new tab..

Treating Acne

Niacinamide’s anti-inflammatory and sebum-regulating properties make it an excellent acne treatment. It not only reduces the occurrence of pimples and blackheads but also helps to fade post-acne marks, promoting a clearer complexion over time.

Reducing Hyperpigmentation

Hyperpigmentation, including dark spots and melasma, can be challenging to treat. Niacinamide works by inhibiting the transfer of melanin to the skin’s surface, thereby reducing the appearance of dark spots and promoting a more even skin tone. Consistent use can lead to significant improvements in skin discolouration.

Enhancing Skin Barrier

A strong skin barrier is essential for maintaining hydration and protecting against environmental aggressors. Niacinamide boosts the production of ceramides, which are lipids that form the skin’s barrier. This enhances the skin’s ability to retain moisture and defend against pollutants, leading to healthier, more resilient skin.

Improving Skin Texture

Niacinamide promotes cell turnover and the production of collagen and elastin, which are vital for maintaining skin’s firmness and elasticity. Regular use of niacinamide can result in smoother, plumper skin with fewer fine lines and wrinkles.

Dermatologist Recommendations

Dermatologists often recommend niacinamide due to its broad range of benefits and minimal risk of side effects.

Its compatibility with other skincare ingredients also makes it a versatile addition to any skincare regimen.

How to Use Niacinamide

Choosing the Right Product

When selecting a niacinamide product, it’s essential to consider the concentration and formulation. Niacinamide is commonly found in concentrations ranging from 2% to 10%. For beginners, starting with a lower concentration is advisable to gauge skin tolerance. Serums are a popular choice due to their lightweight, fast-absorbing nature, but creams and lotions are also effective.

Application Tips

For optimal results, niacinamide should be applied after cleansing and toning but before moisturizing. It can be used both morning and night. To enhance its benefits, it can be layered with other active ingredients such as hyaluronic acid for hydration or retinol for anti-aging. Always follow with sunscreen during the day, as niacinamide can make the skin more sensitive to UV rays.

Potential Side Effects

Niacinamide is generally well-tolerated, but some individuals may experience mild irritation, redness, or itching, particularly when starting a new product. To minimize the risk of adverse reactions, it is advisable to perform a patch test before incorporating niacinamide into your routine. If irritation persists, reducing the frequency of application or consulting a dermatologist is recommended.

Comparing Niacinamide with Other Ingredients

Vitamin C

Both niacinamide and vitamin C are potent antioxidants, but they work differently. Vitamin C is known for its brightening effects and ability to neutralize free radicals. While niacinamide focuses on improving skin barrier function and reducing inflammation, the two can be used together for complementary benefits, provided they are applied in the correct order or formulated together.


Retinol is renowned for its anti-aging properties, promoting cell turnover and collagen production. However, it can be irritating for some users. Niacinamide can help mitigate retinol’s potential irritation while enhancing its anti-ageing effects. This makes the combination highly effective for improving skinOpens in a new tab. texture and reducing fine lines.

Hyaluronic Acid

Incorporating Niacinamide into Your Routine

Daily Skincare Routine

Incorporating niacinamide into your daily skincare routine can be straightforward. Begin with a gentle cleanser to remove impurities, followed by a toner to prep the skin. Apply a niacinamide serum or cream, then follow with moisturizer and sunscreen. At night, niacinamide can be layered with other treatments such as retinol or alpha-hydroxy acids for enhanced results.

Combining with Other Treatments

Niacinamide is compatible with many other skincare treatments, making it easy to integrate into an existing regimen. It can be combined with antioxidants, peptides, and exfoliating acids to target multiple skin concerns simultaneously. However, it is essential to introduce new products gradually to monitor the skin’s response.
