A prescription medication for hypotrichosis called Careprost Plus Original is used to grow eyelashes into longer, darker, and thicker than they have ever been. It is applied to the skin at the base of the eyelashes on the upper eyelid. Never try to rinse your eyes after using the product. The colored part of the iris may become discolored to a brown hue after prolonged use. It should take a few weeks to months for your eyelashes to revert to their original state if you stop using Careprost ophthalmic solution 0.003%. It is also anticipated that the eyelid darkening will go away in a few weeks or months. Give the product to no one; it might not be suitable for their use.
