Human Repeat Insult Patch Test (HRIPT) – Assess Sensitization & Allergenicity
The Human Repeat Insult Patch Test (HRIPT) is a gold-standard clinical study used to evaluate whether a cosmetic, personal care, or topical pharmaceutical product causes skin sensitization or allergic reactions after repeated exposure. It is essential for products intended for frequent or long-term use.
Conducted under strict dermatologist supervision, the product is applied to the same area of skin over multiple cycles—followed by a rest and rechallenge phase—to detect any delayed hypersensitivity reactions. This test is critical for validating claims like “hypoallergenic,” “non-sensitizing,” and “safe for sensitive skin.”
HRIPT supports global regulatory requirements and assures consumers of the product’s long-term safety and tolerance.
