Cobalt folliculitis

Area of Science:

• Dermatology
• Toxicology

Background:

• Cobalt is an essential trace mineral found in vitamin supplements.
• Acne vulgaris and folliculitis are common inflammatory skin conditions.

Purpose of the Study:

• To investigate the relationship between cobalt intake and the development or exacerbation of acne and folliculitis.
• To determine if cobalt in supplements contributes to dermatological lesions.

Main Methods:

• Clinical observation of 60 patients presenting with folliculitis or acne.
• Correlation of dermatological symptoms with cobalt-containing supplement ingestion.
• Assessment of symptom resolution upon cessation of cobalt intake.

Main Results:

• Sixty patients showed a direct link between cobalt ingestion and the development or worsening of acne and folliculitis.
• Dermal lesions significantly improved or resolved after discontinuing cobalt-containing supplements.
• Short-term antibiotic therapy, alongside standard acne treatment, reduced the duration of the eruption.

Conclusions:

• Cobalt ingestion is a potential cause of acne and folliculitis.
• Active acne should be considered a contraindication for vitamin-iron-mineral supplements containing cobalt.
• Further research may explore the specific mechanisms of cobalt-induced dermatological reactions.
