When it comes to beauty products like Careprost, it’s important to know how long they’ll stay safe and useful. 

Careprost is a well-known eyelash serum that helps your lashes grow luscious, black, and thick.

Careprost is also used to treat medical conditions like Glaucoma, Ocular Hypertension, and Hypotrichosis of eyelashes.

Like all other cosmetic or medicinal products, Careprost has an expiry date.

This article will answer the question, “does Careprost expire?” and look at the signs that can help you determine if the medicine is expired.

What is the shelf life of Careprost

Careprost, like most medicines, has an expiration date that shows how long it can stay on the shelf.

The main ingredient, Bimatoprost, and the stabilizers used in this eye care product affect how long it stays good.

Since Bimatoprost is the main ingredient in Careprost, it has a lot to do with the shelf life of Careprost.

Research shows that Bimatoprost usually keeps working for about 43 days, with a possible difference of up to 3.4 days.

Bimatoprost is a stable molecule that does not break down unless kept in a cold place.

So, people can use Careprost without worrying about side effects for over a month.
