Dense hyperpigmentation is most commonly found on which area?

• A. The lips
• B. The cheeks
• C. The tongue
• D. The chin

Answer: (A)

Dense hyperpigmentation shows up where pigment sits most densely in the tissue and is held most readily over time. The lips have a vermilion border that is relatively thin and richly vascularized, so pigment deposited there tends to sit close to the surface and show up more densely. This makes color differences and pigmented areas on the lips appear more pronounced than on other areas. In contrast, the cheeks, tongue, and chin have different tissue characteristics (thicker skin, less pigment retention, or less surface exposure) that typically result in less dense hyperpigmentation.
