Shein Girls' Mesh Mermaid Dress & Headband Set
Summary
Shein Girls' Mesh Mermaid Dress & Headband Set scores 1/100. Independent lab testing by Greenpeace (2025) found formaldehyde at 3.5x the EU REACH legal limit — in a children's costume. Formaldehyde is a known carcinogen and mutagen that can damage DNA, leading to cancer and genetic disorders. It also causes irritation of skin, eyes, and respiratory system. Especially dangerous for children who may mouth fabric. A nearly identical Shein costume exceeded formaldehyde limits in Greenpeace's 2022 study — showing Shein has not fixed this problem.
