Description

Niacinamide, also known as nicotinamide or vitamin B3, is a versatile and well-researched skincare ingredient with multiple benefits for various skin types and concerns. This water-soluble vitamin plays a crucial role in cellular energy production and repair processes within the skin.

Niacinamide is renowned for its ability to improve skin barrier function by increasing ceramide production, which helps retain moisture and protect against environmental stressors. It has been shown to regulate sebum production, making it beneficial for those with oily or acne-prone skin. The ingredient also demonstrates anti-inflammatory properties, helping to soothe redness and irritation associated with various skin conditions.

Clinical studies have indicated that niacinamide can effectively reduce the appearance of fine lines, wrinkles, and hyperpigmentation by inhibiting melanosome transfer to keratinocytes. It also promotes collagen production, contributing to improved skin elasticity and firmness. Typically used at concentrations between 2% and 5% in skincare formulations, niacinamide is generally well-tolerated and can be combined with other active ingredients to enhance overall skin health and appearance.
