Trybello has published a new educational guide comparing prostaglandin-based and peptide-based lash serums. The resource explains how different formulations work, reviews published medical research, and outlines the documented benefits and potential risks associated with commonly used ingredients to help consumers make informed purchasing decisions.

Millions of consumers use eyelash serums to improve lash length and fullness, but growing awareness of potential ingredient safety risks has prompted closer scrutiny of some formulations. Medical experts are therefore advising consumers to examine the active ingredients in cosmetic lash serums, particularly as research has linked certain prostaglandin analogs to eye and eyelid side effects. Against this backdrop, the latest guide from Trybello has been developed to facilitate informed consumer choices.
The guide highlights recent regulatory and medical developments surrounding prostaglandin analogs used in some cosmetic lash serums. In 2026, the European Union's Scientific Committee on Consumer Safety concluded that several prostaglandin analogs commonly used in cosmetic products could not be considered safe for cosmetic use under the conditions assessed. Medical literature has also documented side effects associated with prostaglandin-based formulations, including eyelid irritation, skin darkening around the eyes, changes in orbital fat, and, in rare cases, permanent iris discoloration. Trybello's guide emphasizes that not every user experiences these effects, but understanding the ingredients remains an important part of selecting an appropriate product.
Alongside reviewing prostaglandin-based formulas, the guide examines peptide-based alternatives, including Trybello's own lash serum, explaining how these ingredients differ in their mechanism of action and reported safety profile. Rather than recommending a single product, the comparison is designed to help readers evaluate ingredient lists, understand the available evidence, and balance desired cosmetic outcomes with individual preferences and risk tolerance.
According to Trybello, the guide was developed for consumers researching lash serums before making a purchase, as well as existing users wishing to better understand the products they apply near the eye area.
