Dermatest® No Tears Seal

Dermatest
The eyes are among the most sensitive and fragile organs in the human body. Exposed daily to environmental irritants, even minor carelessness can trigger discomforts such as dryness, stinging, and redness. Certain ingredients commonly found in modern skincare and makeup products—fragrances, preservatives, and detergents—often cause a "burning sensation" or tearing when washing the face, removing makeup, or applying face masks. Such irritation not only diminishes the user experience but, in severe cases, may inflict microscopic damage to the cornea or conjunctiva—particularly for infants, individuals with sensitive skin, or those with dry eye syndrome.
To help consumers feel more confident when choosing eye and facial care products, Germany's Dermatest GmbH has introduced the "No Tears" certification seal, which scientifically verifies a product's eye‑gentleness and awards a trusted certification mark.
What is the Dermatest® No Tears seal?
The Dermatest® No Tears seal is an authoritative mark designed to assess a product's eye‑gentleness, scientifically determining its level of irritation to the sensitive eye area. Through Dermatest's rigorously designed "no‑tears formula" test, products can reliably demonstrate their exceptional mildness.
The Dermatest® No Tears seal has the following three core features:
◎Standardized Eye Irritation Test Model — Consumer Safety Assurance
◎Ethical Standards — Preventing Harm to Testers
◎High-quality in vitro studies—conducting realistic tests using human corneal-like cells
