  • how severe the hyperpigmentation (darkness) is under your arms
  • what is causing the darkness (and whether that has been controlled)
  • The concentration of niacinamide being used
  • your skincare routine
  • your skin itself (how well or not well it reacts to the serum)

Less severe hyperpigmentation will significantly improve in 2 weeks while more severe cases will take longer.
