How to Use This Tool
Paste the ingredient list from your exact package or the brand's current official label, then click Screen Ingredient List. The tool checks exact normalized names against its reference list. An ingredient outside the list appears as Not assessed.
Formulas can change, and retailer listings can lag behind. Do not use an old review, marketplace listing, or another person's bottle as proof of your product's current formula.
What We Check For
Prostaglandin Analogs
The checker looks for the seven exact names published below. It includes isopropyl cloprostenate and bimatoprost. Bimatoprost is the active ingredient in prescription Latisse; its drug label includes specific warnings and adverse reactions. Those findings do not automatically prove that every cosmetic analogue has the same effects.
A match means the label contains a name covered by this version. No match means only that none of those seven names was detected. It is not a safety clearance. The tool can miss different spellings, unlisted synonyms, new ingredients, or incomplete labels.
Ingredients with Reference Notes
The database includes reference notes for a small set of preservatives, fragrance ingredients, and solvents. A note is not a diagnosis or a complete risk assessment. The label alone usually does not show concentration, exposure, or how the finished formula behaves.
Peptide Names
The tool identifies peptide names such as myristoyl pentapeptide-17 and links them to our peptide evidence guide. A name match does not prove that one peptide grows eyelashes or that the finished serum is safe. Evidence from a multi-ingredient formula cannot show which ingredient caused a result.
What This Screen Can and Cannot Tell You
The results use four bounded labels:
- Covered name detected: An exact name from the published prostaglandin list appears on the label.
- Reference note: The database has a limited note that needs context.
- Listed in reference: The tool recognizes the name but does not assess the finished formula.
- Not assessed: The ingredient is outside this tool's database.
None of these labels is an overall safety score. Ask a qualified clinician about eye disease, glaucoma medicine, pregnancy or nursing, prescription products, or persistent irritation.
Prostaglandin Names Covered by This Checker
Coverage version: 2026-07-11. This version checks exact names after ignoring capitalization and extra spaces. It does not claim to cover every prostaglandin analogue, synonym, spelling, or future ingredient.
| Exact Covered Name | Name Note | Reference Boundary |
|---|---|---|
| Isopropyl Cloprostenate | IPCP is the abbreviation used in SCCS/1680/25. The checker matches the full name only. | Read the entity page for the dated SCCS and Health Canada context. |
| Bimatoprost | Bimatoprost is the active drug in LATISSE. A product name is not an ingredient synonym. | Prescription drug evidence applies to the labeled product, dose, route, and indication. |
| Ethyl Tafluprostamide | The Danish EPA report uses this common name for the ingredient whose INCI name is DDDE. | Included as an exact checker name. This row does not make a current product claim. |
| Dechloro Dihydroxy Difluoro Ethylcloprostenolamide | Full INCI name; SCCS abbreviation DDDE. | Included as an exact checker name. Read the family page for source-bounded evidence. |
| Trifluoromethyl Dechloro Ethylprostenolamide | The checker matches this full name only and does not assume an alias. | Included as an exact checker name. This row does not establish effects or equivalence. |
| Methylamido Dihydro Noralfaprostal | SCCS abbreviation MDN. | Included as an exact checker name. Read the family page for the February 2026 SCCS opinion. |
| Cloprostenol Isopropyl Ester | Documented chemical name for isopropyl cloprostenate in SCCS/1635/21. | Matched as its own label string and routed to the isopropyl cloprostenate evidence page. |
If the checker finds one of these exact names, use the linked evidence page or our lash serum side effects guide to understand what the available sources do and do not show. A missing match is not proof that a product is prostaglandin-free or safe.
Frequently Asked Questions
How do I know if my lash serum has prostaglandin?
Compare the label with the seven exact names in the coverage table above, or paste it into the checker. The tool ignores capitalization and extra spaces. It does not cover every possible analogue, synonym, or spelling. No covered name detected is not a safety clearance.
Are prostaglandin-free lash serums effective?
Evidence for non-prostaglandin lash serum ingredients is limited. A small uncontrolled study of one multi-ingredient formula cannot prove that a single peptide caused the result or that peptides work like prescription bimatoprost. Read our peptide evidence guide and prostaglandin-free guide for the evidence limits and product comparisons.
What ingredients should I avoid in lash serum?
A label screen cannot create one universal avoid list. Start by checking for the seven covered prostaglandin names, known personal allergies, and instructions or warnings on the package. An unknown ingredient is Not assessed, not cleared. Ask a clinician about eye disease, glaucoma medicine, pregnancy or nursing, prescription products, or persistent irritation.
What is the safest lash serum?
This checker cannot name one safest serum. Safety depends on the exact formula, amount, use, health history, and evidence available. Use the screen to find covered names and reference notes, then verify the current label and ask a qualified clinician when medical questions apply.
