Prostaglandins in lash serums
Prostaglandins are naturally occurring, hormone-like compounds in the body that help regulate processes such as inflammation and tissue signaling.
In cosmetics, some lash serums use prostaglandin analogues β ingredients designed to mimic prostaglandin activity β to stimulate faster lash growth.
Because these ingredients interact with biological pathways, results can appear noticeable for some users.
However, they were originally developed for medical use β not cosmetic enhancement.
why we are prostaglandin-free
While prostaglandin analogues can promote visible growth, many consumers report unwanted side effects around the eye area, including irritation or darkening of the skin.
The eye contour is one of the most delicate areas of the face.
We believe growth should not come at the cost of comfort.
