# What Is Isopropyl Cloprostenate in Lash Serum?

**Plain answer:** Isopropyl cloprostenate is a lab-made prostaglandin analogue in some lash serums. It is not bimatoprost, the drug in LATISSE. Health Canada lists this ingredient family as prohibited in cosmetics. In 2026, an EU science panel reviewed this exact name. It said the ingredient could not be considered safe for lash and brow growth products.

This page is a source-checked editorial draft. It is not medically reviewed and remains noindex until the correct qualified reviewer approves the exact page version.

## Evidence approach

Effectiveness is graded separately from safety. A finished-formula study does not prove that one ingredient caused the result. A regulator or safety-panel conclusion is limited to the exact ingredient, use, concentration, and jurisdiction it names.

**Effectiveness grade key:** A = strong controlled human evidence for the exact use. B = one controlled human study. C = a small uncontrolled human formula study. D = laboratory, animal, scalp-hair, or supplier evidence. E = label presence, theory, or no direct human eyelash evidence. Grades do not rate safety.
