The Human Repeat Insult Patch Test (HRIPT) is a gold-standard clinical study used to evaluate skin irritation and sensitization potential of cosmetic products.
Conducted under controlled conditions on human volunteers, HRIPT assesses whether repeated exposure to a product may cause irritation or allergic reactions. This test provides robust safety data to support product safety assessments and regulatory submissions, particularly for products intended for prolonged or repeated skin contact.
