Summary
Lip color diversity varies significantly across Asian, African American, Hispanic, and Caucasian women. This study developed a 53-tone lip color chart to guide inclusive cosmetic product development.
Area of Science:
- Cosmetic Science
- Facial Aesthetics
- Human Physiology
Background:
- Lips are crucial for social interaction and makeup, yet lip color data is scarce compared to skin.
- Understanding lip color diversity is essential for inclusive cosmetic product development.
Purpose of the Study:
- To assess lip color diversity across Asian, African American, Hispanic, and Caucasian ethnicities.
- To develop a standardized lip color chart for cosmetic industry reference.
Main Methods:
- Hyperspectral imaging (SpectraFace®) was used to measure natural lower lip color.
- 514 women aged 19-68 across the USA, France, and China participated.
- Lip color data was analyzed for diversity and inter-ethnic overlaps.
Main Results:
- Significant lip color variation was observed within and between the four ethnic groups.
- Substantial overlap in lip tones was found between Hispanic and Asian women.
- A 53-tone lip color chart, based on lightness and hue, was created, with Hispanic women represented across 32 tones.
Conclusions:
- Lip color is not solely determined by ethnicity, as evidenced by inter-group overlaps.
- The developed lip color chart serves as a global reference for lip color assessment.
- The 53 defined lip tones can guide the creation of more inclusive nude lipstick shades.

Changes in Skin Color: Clinical Perspectives

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.

Pigmentation
4.1K
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...

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
