'Fishy' Make-up on the Hook for Mercury Exposure: A Case Series

Area of Science:

• Environmental Toxicology
• Dermatology
• Public Health

Background:

• Topical application of mercury-containing skin-lightening cosmetics is a known health risk.
• Extremely high hair mercury concentrations indicate significant inorganic mercury exposure.

Purpose of the Study:

• To investigate the source and health outcomes of four Barbadian women with exceptionally high hair mercury levels.
• To identify the role of mercury-containing cosmetics in severe mercury poisoning.

Main Methods:

• Hair and urine mercury analysis conducted at an accredited toxicological laboratory.
• Clinical examinations performed on-site to assess patient health status.

Main Results:

• Hair mercury concentrations ranged from 361-5617 µg/g, far exceeding normal levels.
• Elevated urine mercury levels (7-135 µg/L) confirmed systemic mercury exposure.
• Clinical symptoms were consistent with, but nonspecific to, chronic mercury exposure.

Conclusions:

• Mercury-containing cosmetics with dangerous levels of mercury are accessible in Barbados.
• An immediate and complete ban on these hazardous cosmetic products is urgently needed.
