Niacinamide

Also-called: Nicotinamide, Vitamin B3 | Function: Anti-acne, Soothing, Skin brightening, Cell-signaling ingredient

Niacinamide, also known as vitamin B3, is a potent skincare ingredient renowned for its wide-ranging benefits.

It helps to strengthen the skin's barrier function, improve skin texture, and reduce the appearance of fine lines and wrinkles. It's also effective in managing acne and reducing redness and inflammation.

Furthermore, it inhibits melanin production, thereby assisting in fading hyperpigmentation and evening out skin tone. Safe for almost all skin types, niacinamide is a versatile ingredient found in various skincare products.
