Niacinamide, also known as vitamin B3 or nicotinamide, is a versatile cosmetic ingredient with multiple skin benefits. Here are some of its main effects:

Hydration: Niacinamide can improve the barrier function of the skin, reducing transepidermal water loss and thus keeping the skin hydrated and soft.

Wrinkle Reduction: It is known for its anti-aging properties, as it can stimulate collagen production and reduce the appearance of wrinkles and fine lines, making the skin more toned and elastic.

Even skin tone: Niacinamide can reduce hyperpigmentation, dark spots and discoloration, thus contributing to a more even and brighter skin tone.

Anti-inflammatory Properties: It is effective in reducing skin inflammation, making it useful for treating conditions such as acne, rosacea, and other forms of skin irritation.

Regulation of sebum production: Niacinamide can regulate the skin's sebum production, thus reducing shine and preventing the formation of acne and blackheads.

Protection from environmental damage: It has antioxidant properties that help protect the skin from damage caused by free radicals and UV rays, thus reducing the signs of premature aging.

Compatibility with all skin types: Niacinamide is generally well tolerated by all skin types, including sensitive skin, and can be used in combination with other ingredients without causing irritation.

Stretch mark treatment: It can improve the appearance of stretch marks by reducing their pigmentation and stimulating skin regeneration.

Pore ​​Shrinking: Niacinamide can help reduce the appearance of enlarged pores, making skin appear smoother and more even-toned.

Niacinamide, therefore, is a highly effective cosmetic ingredient with multiple benefits for the health and appearance of the skin. It is widely used in a wide range of skin care products, such as moisturizers, serums, sunscreens and anti-aging treatments.
