Lash serum questions

What are prostaglandins in lash serums?
Prostaglandins are substances involved in processes in the body. Analogues are related compounds; some lash products use them to affect eyelash growth. Read the prostaglandin guide.
What side effects can prostaglandins cause?
Reported effects include irritation, darker eyelid skin and changes to tissue around the eyes. They depend on the ingredient and how it is used. This checker identifies ingredient names; it does not assess a product's safety. Read about reported side effects.
How many names do prostaglandins go by?
There is not one label name for the whole group. This checker covers 15 names and ingredient groups, plus some spelling and formatting variations. It cannot find every possible compound. Explore ingredient names.
Are prostaglandins banned anywhere?
Rules vary by country, ingredient and whether the product is a cosmetic or a medicine. A proposal or scientific opinion is not a law. This checker does not tell you whether a product can legally be sold. Read the background on the EU proposal and check the latest rules for your country.
What's the difference between prostaglandin and prostaglandin-free lash serums?
Prostaglandin-based serums contain a prostaglandin or analogue. Formulas made without them may use peptides, botanicals or vitamins instead. Ingredients and results vary by product. Compare the ingredient approaches.
Can you tell prostaglandin concentration from an ingredient list?
No. In the US, cosmetic ingredients at 1% or less can appear in any order after ingredients above 1%. Their position on the label does not tell you the exact amount. Read the lash serum ingredient guide.
