Niacinamide, also known as vitamin B3, is a popular ingredient in skincare due to its many skin health benefits, especially in anti-aging skincare.

First, niacinamide helps protect the skin by strengthening the skin barrier, which is the outermost layer of the skin. A strong skin barrier can prevent outside irritants, such as chemicals and pollution, from penetrating the skin and causing damage. This prevents skin dehydration and maintains healthy skin.

Additionally, niacinamide is a powerful antioxidant that protects the skin from free radical damage. Free radicals are unstable molecules produced by factors such as pollution, cigarette smoke and UV rays. These molecules can damage skin cells and contribute to signs of premature aging such as wrinkles, age spots, and uneven skin texture.

Niacinamide improves skin texture and helps reduce the appearance of fine lines and wrinkles. Studies have shown that it stimulates the production of collagen in the skin, which is an important protein for maintaining the structure and elasticity of the skin. In addition, it helps regulate the production of sebum, which is the skin's natural oil, which helps prevent acne and clogged pores.

Finally, niacinamide has anti-inflammatory properties thanks to which it reduces redness and irritation of the skin, particularly useful for sensitive or eczema-prone skin.
