Dermis thickness ranges from the thinnest on the eyelids to the thickest on the back. Which pair correctly represents these values?

Dermis thickness ranges from the thinnest on the eyelids to the thickest on the back. Which pair correctly represents these values?

• A. 0.5 mm on eyelids and 2.0 mm on the back
• B. 1.0 mm on eyelids and 4.0 mm on the back
• C. 3.0 mm on eyelids and 0.3 mm on the back
• D. 0.3 mm on eyelids and 3.0 mm on the back

Answer: (D)

Dermis thickness varies by location, with the eyelids having the thinnest skin and the back having a much thicker dermis due to underlying tissues. The pair that reflects this pattern uses about 0.3 mm for the eyelid and about 3.0 mm for the back, which lines up with the real-world difference in thickness between these sites. This matters in PMU because pigment is deposited into the dermis, so understanding these depths helps in applying pigment at the appropriate level to avoid going too shallow (fading or scarring) or too deep (reaching subcutaneous tissue). The other options propose eyelid thicknesses that are unrealistically thick for the eyelid or swap the order, which doesn’t match how dermis thickness actually varies.
