Ingredient review
Nortapluprost
INCI: Nortapluprost
Nortapluprost is a synthetic ingredient that can help eyelashes appear longer and fuller, but it may cause irritation and requires careful use.
In plain English
Nortapluprost is a lab-made ingredient similar to a natural substance in your body called prostaglandin. When applied to the base of your eyelashes, it can make them grow longer, thicker, and darker over time. It's often found in eyelash serums, but it can also cause side effects like redness, itching, or darkening of the skin around the eyes.

Quick decision guide
Useful, but context matters
Nortapluprost 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 Nortapluprost.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
Nortapluprost is a synthetic prostaglandin analog, meaning it's a man-made version of a hormone-like compound that naturally occurs in the body. It's specifically designed to stimulate hair growth, particularly on the eyelashes.
How it works
Nortapluprost works by extending the growth phase (anagen phase) of the eyelash hair cycle. It also increases the number of hairs that are actively growing, leading to longer, thicker, and darker lashes over several weeks of consistent use.
Pros
Effective lash growth
Clinical studies show prostaglandin analogs like nortapluprost can significantly increase lash length and thickness within 8-12 weeks.
Long-lasting results
With continued use, the effects on lash appearance can be maintained, and results may persist for weeks after stopping.
Cons and cautions
Potential irritation
Common side effects include eye redness, itching, and a stinging sensation upon application, which can be bothersome for sensitive users.
Skin and iris darkening
Prolonged use may cause darkening of the eyelid skin or even the iris (the colored part of the eye), which can be permanent.
Best for
- Individuals seeking visibly longer and fuller eyelashes
- People who have tried other lash serums with limited results
Use caution if
- Those with sensitive eyes or a history of eye conditions like glaucoma
- Pregnant or breastfeeding women (due to lack of safety data)
Usage tips
Safety summary
Nortapluprost is generally considered safe for topical use at low concentrations, but it carries risks of eye irritation, skin darkening, and potential changes in iris color. It should be used with caution, especially by those with sensitive eyes or pre-existing eye conditions.
Research notes
Research on prostaglandin analogs for eyelash growth is well-established, with studies showing efficacy for bimatoprost and similar compounds. However, specific data on nortapluprost is limited, and most evidence is extrapolated from related ingredients.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 0.03%
- Regulatory status
- Nortapluprost is not approved by the FDA for cosmetic use in the United States, but it is used in some countries as a cosmetic ingredient. Always check local regulations.
- Common uses
- Eyelash serums
- Environmental note
- As a synthetic compound, nortapluprost is produced through chemical synthesis and may have a moderate environmental footprint depending on manufacturing practices.
Good to know
- Nortapluprost is often listed under different names in ingredient labels, so check for prostaglandin analogs.
- Results typically take 8-12 weeks to become noticeable, and consistent use is key.
