- This table underscores why one-size-fits-all timelines fail. A Type I user expecting visible tanning by day three will be disappointed. The biological ceiling for melanin synthesis in low-density melanocyte populations requires 10+ days regardless of dose. Conversely, a Type IV user may reach satisfactory pigmentation by day seven and transition to maintenance earlier than the standard 14-day protocol.
