What Ingredient Makes Eyelashes Grow?
The ingredient that makes eyelashes grow is a prostaglandin analog called bimatoprost. It is a prescription medication that is commonly used to treat glaucoma but has also been approved by the FDA to enhance eyelash growth in people with thin or sparse lashes. Bimatoprost works by prolonging the growth phase of eyelash hair follicles, leading to thicker and longer lashes over time.
