Why we use Niacinamide

↓ skip to summary

The Basics

Niacinamide, also known as vitamin B3, is a versatile and well-researched skincare ingredient celebrated for its multifaceted benefits across various skin types. Its compatibility and efficacy make it a staple in many skincare formulations.

Enhancing Skin Barrier Function

A robust skin barrier is essential for maintaining hydration and defending against environmental aggressors. Niacinamide plays a pivotal role in fortifying this barrier by stimulating the production of ceramides—lipid molecules that retain moisture and protect the skin. This enhancement not only reduces transepidermal water loss but also bolsters the skin's resilience against irritants. Clinical studies have demonstrated that topical application of niacinamide significantly improves the skin's barrier function, leading to increased hydration and elasticity.¹

Regulating Sebum Production and Minimising Pores

Excess oil production can lead to enlarged pores and acne. Niacinamide has been shown to effectively reduce sebum excretion rates, thereby helping to control oiliness and diminish the appearance of pores. A study reported a significant reduction in sebum production and pore size after the use of a 2% niacinamide formulation over four weeks.²

Anti-Inflammatory and Acne Reduction Properties

Niacinamide exhibits notable anti-inflammatory effects, making it beneficial for calming irritated skin and managing conditions like acne. Its ability to suppress pro-inflammatory cytokines aids in reducing redness and inflammation. Comparative studies have found that topical niacinamide is as effective as some antibiotics in treating acne, with the added advantage of a lower risk of dryness, irritation, and antibiotic resistance.²

Addressing Hyperpigmentation and Uneven Skin Tone

Hyperpigmentation and uneven skin tone are common concerns that niacinamide can effectively address. It works by inhibiting the transfer of melanin to the skin's surface, thereby reducing dark spots and promoting a more even complexion. Clinical trials have shown that a 5% niacinamide concentration can lead to significant improvements in hyperpigmentation and skin clarity over 12 weeks.¹

Anti-Aging Benefits: Smoothing Fine Lines and Wrinkles

Niacinamide contributes to anti-aging efforts by supporting collagen production. As a result, this improves skin elasticity and reduces the appearance of fine lines and wrinkles. Its antioxidant properties combat oxidative stress, a key factor in skin aging. Research indicates that regular application of niacinamide results in a 21% improvement in fine lines and a 15% enhancement in skin radiance over 12 weeks.³

Combating Skin Yellowing (Sallowness)

Skin yellowing, or sallowness, often results from the accumulation of advanced glycation end products (AGEs) that affect skin tone and elasticity. Niacinamide's antioxidant capabilities help prevent the formation of AGEs, thereby reducing skin sallowness and promoting a healthier complexion. Clinical evidence supports niacinamide's efficacy in decreasing skin yellowing, contributing to a more youthful appearance.⁴

Synergy with Other Skincare Ingredients

One of niacinamide's standout features is its compatibility with a wide range of skincare ingredients. This flexible active can be combined with retinoids, AHAs, peptides, and basically anything you can think of. This makes it a versatile addition to essentially all skincare routines, enhancing overall efficacy without the risk of adverse interactions.

In summary, niacinamide is a multifaceted skincare ingredient offering a spectrum of benefits. Its talents range from strengthening the skin barrier and regulating oil production to reducing hyperpigmentation and signs of aging. Moreover, its proven efficacy and versatility make it a valuable component in achieving and maintaining healthy, radiant skin.
