Ingredient review
Dihydroxypropyl Didehydrolatanoprostamide
INCI: DIHYDROXYPROPYL DIDEHYDROLATANOPROSTAMIDE
A synthetic prostaglandin analog that can enhance eyelash and brow growth but carries risks of irritation and potential eye-area side effects.
In plain English
This ingredient is a lab-made compound similar to a natural substance called prostaglandin. When applied to the base of eyelashes or eyebrows, it can make them grow longer, thicker, and darker over time. However, it can also cause redness, itching, or darkening of the skin around the eyes, and in rare cases, may affect eye pressure or color.

- Step 1Start with the score, then check the irritation and clogging risk before judging Dihydroxypropyl Didehydrolatanoprostamide.
- 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 prostaglandin, a lipid compound that naturally occurs in the body and influences hair growth cycles.
How it works
It extends the growth phase (anagen) of eyelash and brow hairs, encouraging them to grow longer and fuller. It also increases the number of hairs that are actively growing at any given time.
Pros
Effective growth stimulation
Clinical studies show significant increases in lash length and thickness within weeks, making it a powerful option for those wanting dramatic results.
Non-invasive alternative
Offers a topical solution for enhancing lashes and brows without the need for extensions, tints, or surgical procedures.
Cons and cautions
Eye-area irritation risk
Common side effects include redness, itching, and burning at the application site, which can be uncomfortable and may discourage continued use.
Potential for skin darkening
Hyperpigmentation of the eyelid skin can occur, especially if the product is applied outside the lash line, and this change may be slow to fade.
Best for
- People seeking longer, fuller eyelashes
- Individuals with sparse brows who want a non-invasive option
Use caution if
- People with glaucoma, high eye pressure, or eye inflammation
- Pregnant or nursing women (due to lack of safety data)
Usage tips
Safety summary
Generally safe for topical use on lashes and brows when applied correctly, but carries moderate irritation risk and potential for skin darkening. Not recommended for those with eye conditions or during pregnancy.
Research notes
Clinical studies support its efficacy for lash growth, with most evidence coming from analog studies (e.g., bimatoprost). Long-term safety data on iris color change and eye pressure effects are limited for this specific compound.
Common label clues
- Typical concentration
- 0.01% to 0.03%
- Regulatory status
- Approved for cosmetic use in many regions, but not FDA-approved for over-the-counter lash growth; some countries restrict its concentration.

- Eyelash serums, Brow treatments
- Environmental note
- Synthetically produced, so no direct environmental impact from harvesting, but disposal of unused product should follow local guidelines.
Good to know
- Results are not permanent; lashes will return to their original state if you stop using the product.
- This ingredient is often found in lash serums alongside conditioning agents like panthenol and hyaluronic acid.
