Dense hyperpigmentation is most commonly found on which area in cosmetic procedures?

• A. Cheeks
• B. Nose
• C. The lips
• D. Ears

Answer: (C)

Pigment density in cosmetic procedures is influenced by tissue type, with mucosal areas like the lips tending to hold pigment more densely. The lips are a thin, highly vascular mucous membrane, so pigment deposited there sits closer to the surface and tends to stay concentrated as healing occurs. Moisture, movement, and the thinner epidermis mean pigment can appear darker and more saturated compared with thicker-skinned areas. In contrast, areas with thicker skin and more subcutaneous tissue—like the cheeks or nose—tend to diffuse pigment more during healing, producing a less dense appearance. Ears are not a common site for lip-focused pigmentation and don’t typically show that same density.
