Ingredient review
Trifluoromethyl Dehydrolatanoprost
INCI: Trifluoromethyl Dehydrolatanoprost
A synthetic prostaglandin analog that may promote eyelash growth but carries risks of irritation and potential side effects.
In plain English
This ingredient is a lab-made compound similar to a natural substance called prostaglandin. In eyelash serums, it can help lashes grow longer and thicker by extending the growth phase of the hair cycle. However, it can also cause redness, darkening of the eyelid skin, and changes in eye color, so it requires careful use.

Quick decision guide
Useful, but context matters
Trifluoromethyl Dehydrolatanoprost can be useful, but watch for some irritation potential.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Trifluoromethyl Dehydrolatanoprost.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English
Irritation risk
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic analog of a prostaglandin, a lipid compound that naturally occurs in the body and influences hair growth cycles.
How it works
It binds to prostaglandin receptors in the hair follicle, prolonging the anagen (growth) phase and increasing the number of hairs that are actively growing, leading to longer, thicker lashes.
Pros
Effective lash growth
Clinical studies show it can significantly increase lash length and thickness within weeks.
Convenient application
Applied once daily as part of a nighttime routine, similar to other lash serums.
Cons and cautions
Irritation risk
Common side effects include eye redness, itching, and darkening of the eyelid skin, which can be bothersome.
Potential eye color change
Rare but irreversible darkening of the iris has been reported, especially with prolonged use.
Best for
- Individuals seeking longer, thicker eyelashes
- Those who have tried other lash serums with limited results
Use caution if
- People with glaucoma or other eye conditions
- Those with sensitive eyes or contact lens wearers
- Pregnant or breastfeeding women
Usage tips
Safety summary
Generally considered safe for topical use at low concentrations, but carries risks of local irritation, skin darkening, and rare iris color changes. Not recommended for those with eye conditions or during pregnancy.
Research notes
Clinical studies support its efficacy for eyelash growth, but long-term safety data is limited. Most evidence comes from studies on similar prostaglandin analogs used in ophthalmology.
Common label clues
- Typical concentration
- Typically used at very low concentrations (0.01% or less)
- Regulatory status
- Approved for cosmetic use in some countries but may be regulated as a drug in others due to its pharmacological activity. Always check local regulations.
- Common uses
- Eyelash serums
- Environmental note
- Synthetic production has a moderate environmental footprint; no specific biodegradability data available.
Good to know
- This ingredient is often found in prescription-strength lash serums and may not be available in over-the-counter products.
- Always patch test a small area behind the ear before full use to check for sensitivity.
