Cooperative Activity Week 5
Tattoos inject dye into the skin using small needles that puncture skin at a frequency of 50-3000 times per minute.
The needles penetrate past the epidermis into the underlying dermis, leaving behind pigment in the entire area.
Initially, the ink is deposited in both epidermis and dermis, but as skin heals, the color may look less deep and
vibrant. Based on your understanding of the skin structure, how can you explain the change in the appearance of the
color over time?
