Area of Science:

  • Dermatology
  • Allergology
  • Cosmetic Science

Background:

  • Topical formulations are widely used for skin care.
  • Adverse skin reactions can occur with cosmetic product application.
  • Identifying specific allergens is crucial for managing contact dermatitis.

Observation:

  • A 45-year-old woman presented with a severe eczematous reaction.
  • The reaction was localized to the application site of a clarifying cream.
  • The patient had no prior history of similar reactions.

Findings:

  • Patch testing was performed to identify the causative agent.
  • The patch test results were positive for vitamin K1.
  • This indicates a specific allergy to vitamin K1 in the tested individual.

Implications:

  • Vitamin K1 can act as a contact allergen in topical formulations.
  • Clarifying creams containing vitamin K1 may pose a risk for sensitized individuals.
  • Further investigation into the prevalence of vitamin K1 allergy in cosmetic dermatitis is warranted.
