Summary
This study mapped body skin pigmentation in young Chinese females, identifying the neck, heels, elbows, and popliteal space as having the most severe pigmentation. This provides crucial baseline data for understanding skin color variations.
Area of Science:
- Dermatology
- Anthropometry
- Cosmetic Science
Background:
- Facial skin color studies are common, but body skin pigmentation variations are less understood.
- Body skin pigmentation is a significant aesthetic concern for many individuals.
Purpose of the Study:
- To establish baseline body skin pigmentation data for young Chinese females.
- To comprehensively assess body skin color variations across different anatomical sites.
- To develop a detailed body skin pigmentation map.
Main Methods:
- Measured individual type angle (ITA°) and melanin index (MI) across 100 body points.
- Utilized CL 400 for ITA° and MX 18 for MI measurements.
- Collected data from 20 young Chinese females, totaling 12,000 measurements.
Main Results:
- Significant differences in pigmentation were observed between symmetrical body points.
- The most heavily pigmented areas identified were the back of the neck, heels, elbows, and popliteal space.
- Variations were noted across various anatomical locations, including clavicle, wrists, groin, and ankles.
Conclusions:
- This research presents the first comprehensive body skin pigmentation map.
- The study highlights specific areas of higher pigmentation in young Chinese women.
- Findings contribute valuable data for cosmetic and dermatological applications.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
