{"title":"Niacinamide Skincare — Vitamin B3 Serums and Formulas for Sensitive, Oily, and Acne-Prone Skin","description":"\u003ch2\u003eWhat Niacinamide Does — and Why Concentration Matters\u003c\/h2\u003e\n\u003cp\u003eNiacinamide is the amide form of vitamin B3 and a precursor of NAD⁺ — nicotinamide adenine dinucleotide — an essential coenzyme involved in cellular energy production and DNA repair. In skin, NAD⁺ levels decline with age, which contributes to slower cell repair, weakened barrier function, and increased visible aging. Topical niacinamide helps replenish this pathway.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAt the skin surface, niacinamide works through multiple simultaneous mechanisms. It stimulates ceramide synthesis, which directly strengthens the lipid barrier and reduces transepidermal water loss. It inhibits the transfer of melanosomes from melanocytes to keratinocytes, which is the mechanism responsible for its visible brightening and hyperpigmentation-reducing effect. It regulates sebaceous gland activity, reducing excess sebum without stripping. And it exerts measurable anti-inflammatory activity, making it particularly effective for acne-prone, rosacea-adjacent, and reactive skin that does not tolerate more aggressive actives.\u003c\/p\u003e\n\u003ch3\u003e5% vs 10% — which concentration is right\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e5% niacinamide\u003c\/strong\u003e is the concentration at which brightening, barrier support, and redness reduction are clinically documented.
