How it works
N-acetyl glucosamine and niacinamide block melanin production by interfering in the process at two different points - reducing formation and appearance of age spots.
A key enzyme in melanin biosynthesis is tyrosinase. It is initially produced in the cell as an inactive pro-enzyme, which is then glycosylated to the active form.

Niacinamide and N-acetyl Glucosamine
What it does
Both N-acetyl glucosamine and niacinamide significantly reduce: amount and appearance of hyperpigmentation,melanized hyperpigmented spots and uneven melanin distribution, melanin content in skin cells in culture
