COSRX Snail Mucin Allergy Investigation

Migliaccio & Rathod LLP is investigating whether COSRX failed to adequately warn consumers that its snail mucin skincare products may trigger allergic reactions in individuals with shellfish or mollusk allergies.

COSRX’s Advanced Snail 96 Mucin Power Essence and other snail mucin products have become some of the company’s most popular skincare products. However, dermatologists and consumers have increasingly reported that some individuals with shellfish or mollusk allergies may experience allergic reactions after using snail mucin products. Despite these reports, consumers allege that the product labeling does not adequately warn purchasers about the potential for cross-reactivity before use.

Consumers with known shellfish allergies may reasonably expect manufacturers to disclose material allergy risks that could influence purchasing decisions.

What Consumers Report

Consumers report:

  • Purchasing COSRX snail mucin products believing they were safe for routine use.
  • Experiencing skin irritation, hives, swelling, burning, or allergic reactions after application.
  • Learning only after the reaction that snail mucin may cross-react with shellfish allergies.
  • Seeking medical treatment or discontinuing use of the product.
  • Feeling they would have chosen different skincare products had adequate warnings been provided.
  • Paying premium prices for products marketed as gentle and suitable for sensitive skin.

Why Consumers Should Be Concerned

Manufacturers have a responsibility to provide material safety information that allows consumers to make informed purchasing decisions. Consumers with known allergies may choose different skincare products if they are adequately warned about potential cross-reactivity before using the product.

This investigation seeks to determine whether COSRX adequately warned consumers regarding potential allergy risks associated with snail mucin ingredients.

Potential Claims May Include

  • Failure to Warn
  • Consumer Protection
  • False Advertising
  • Breach of Implied Warranty
  • Unjust Enrichment
