Ingredient review
Dihydroxypropyl Dehydrolatanoprostamide
INCI: Dihydroxypropyl Dehydrolatanoprostamide
A synthetic prostaglandin analog that can boost eyelash growth but may cause irritation and requires careful use.
In plain English
This ingredient is a lab-made compound similar to a medication used for glaucoma. When applied to the lash line, it can make eyelashes grow longer, thicker, and darker. However, it can also cause redness, itching, or darkening of the skin around the eyes, and it may change eye color in rare cases.

Quick decision guide
Read the cautions before using
Dihydroxypropyl Dehydrolatanoprostamide 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 Dihydroxypropyl Dehydrolatanoprostamide.
- 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
A synthetic derivative of latanoprost, a prostaglandin analog originally developed to treat glaucoma. In cosmetics, it is used to stimulate eyelash growth.
How it works
It mimics a natural signaling molecule (prostaglandin) that tells hair follicles to stay in the growth phase longer, resulting in longer, denser lashes over several weeks of consistent use.
Pros
Effective lash growth
Clinical studies show it can significantly increase lash length and thickness within weeks.
Noticeable results
Many users see visible improvement in lash density and darkness, reducing the need for mascara.
Cons and cautions
Risk of irritation
Common side effects include redness, itching, and a stinging sensation at the application site.
Potential for pigmentation changes
May cause darkening of the eyelid skin or, in rare cases, a permanent change in iris color.
Best for
- People wanting visibly longer and fuller eyelashes
- Those who have tried other lash serums with limited results
Use caution if
- Individuals with sensitive eyes or contact lens wearers
- Those with a history of eye inflammation or glaucoma
Usage tips
Safety summary
Generally safe when used as directed, but can cause eye irritation and pigmentation changes. Avoid contact with the eye itself. Not recommended for people with eye conditions.
Research notes
Clinical studies confirm efficacy for lash growth, but long-term safety data on cosmetic use is limited. Most evidence comes from glaucoma research.
Common label clues
- Typical concentration
- Typically 0.01% to 0.03%
- Regulatory status
- In the US, prostaglandin analogs for lash growth are regulated as drugs by the FDA. In the EU, they are considered cosmetic ingredients but must meet safety requirements.
- Common uses
- Eyelash serums
- Environmental note
- Synthetic production has a moderate environmental footprint; no specific sustainability concerns are widely reported.
Good to know
- Results typically appear after 4–8 weeks of daily use.
- This ingredient is often found in 'lash growth' serums and is regulated as a cosmetic in some regions but as a drug in others.
