Later, many institutions began to study niacinamide, and gradually confirmed the effectiveness of niacinamide in delaying skin aging, inhibiting melanin deposition, and whitening. Niacinamide has begun to be used in skin care products on a large scale, and has the title of "whitening artifact". Niacinamide has a whitening effect because it can inhibit the deposition of melanin, block the transfer of melanin to surface cells, and accelerate the shedding of keratin containing melanin, dilute the yellowing of protein glycation, and reduce the size and number of spots. Niacinamide can promote the microcirculation of the dermis, maintain the skin's moisture content (that is, moisturizing) and reduce the damage of free radicals to the skin. Therefore, it can slow down skin aging and enhance skin defenses, and it is also widely used in anti-aging products.
