Detailed answer

Niacinamide, also known as vitamin B3, is a versatile ingredient in moisturizers. It helps improve the texture of the skin by promoting collagen production and increasing ceramide production, which boosts hydration and improves elasticity. Niacinamide is also effective in reducing hyperpigmentation by inhibiting the transfer of melanin between skin cells, leading to a more even skin tone. Additionally, niacinamide strengthens the skin barrier by increasing the production of fatty acids and ceramides, which helps prevent moisture loss and protects the skin against environmental stressors. It is well-tolerated by most skin types, making it suitable for a wide range of individuals.
