What is niacinamide and how does it work?
Niacinamide, also known as nicotinamide or vitamin B3, is a water-soluble molecule that the skin uses as a precursor to two key coenzymes: NAD+ and NADP+. These molecules are the true "batteries" of your skin cells: they power energy production, DNA repair, and the synthesis of lipids that make up the skin's protective barrier.
In practice, by applying niacinamide to your skin, you provide it with the fuel it needs to function optimally. It stimulates ceramide production — those lipids that seal in moisture and limit water loss — while regulating sebaceous gland activity. This dual action explains its reputation: it suits oily skin as well as dry or sensitive skin, which is rare for such a powerful active ingredient.
Another important mechanism: niacinamide acts on the transfer of melanosomes, these small pigment sacs responsible for dark spots. By slowing their migration to the skin's surface, it helps to even out skin tone and reduce marks left by imperfections or sun exposure.
💡 Common misconception
“Niacinamide is not suitable for sensitive skin.” False. On the contrary, it is one of the best-tolerated active ingredients on the market. Unlike exfoliating acids or retinol, it does not cause stinging or flaking. At cosmetic concentrations (2 to 5%), it even strengthens the skin barrier and reduces reactive redness.
Proven benefits of niacinamide
Few active ingredients can boast such a broad spectrum of action. Niacinamide visibly tightens enlarged pores by regulating sebum and improving the elasticity of the follicular opening. It mattifies the complexion without drying, making it a valuable ally for combination to oily skin.
In terms of radiance, it evens out skin tone and reduces pigment spots, restoring luminosity to dull or marked skin. It also has soothing and anti-redness properties, which are appreciated for reactive skin. Finally, by strengthening the lipid barrier, it improves hydration in the long term and contributes to an anti-aging effect by supporting skin firmness and texture.
What it does NOT do, however, is important to know: niacinamide is not an exfoliant and does not "strip" the skin. It does not replace sun protection — no active ingredient does. And its effects on spots or pores require regularity: allow 4 to 8 weeks of daily use before observing visible results. It is not an immediate "radiance boost" active ingredient, but a long-term investment in skin health.
🔬 Expert advice
Niacinamide pairs with almost everything: hyaluronic acid, peptides, retinol, floral antioxidants. The old concern about incompatibility with vitamin C is now largely nuanced — in modern cosmetic formulas, the two coexist without problems. To maximize results, apply it morning and night on clean skin, before your richer treatments.

How LILI MARGO integrates niacinamide into Floractiv20+®
At LILI MARGO, niacinamide never acts alone. It is designed in synergy with the patented Floractiv20+® technology, which brings together 20 floral extracts and 15 anti-aging factors.

This approach allows you to benefit from the advantages of vitamin B3 — radiance, tightened pores, regulated sebum — while respecting the skin's balance thanks to floral extracts that reinforce the soothing and moisturizing effect.

📌 Key takeaway

How to apply: the steps
Niacinamide is easily integrated into any routine. After cleansing, apply your niacinamide serum to clean, dry skin, morning and night. Gently massage a few drops onto your entire face, avoiding the eye area. Allow to absorb for a few seconds, then follow with your moisturizer.
In the morning, always finish with sun protection: niacinamide works deep on spots, but SPF prevents their reappearance. In the evening, you can combine it with an anti-aging active ingredient like retinol or peptides — niacinamide also helps limit irritation sometimes associated with retinol. No need to overdo it: a concentration of 2 to 5% is more than enough, and regularity always trumps quantity.
