Latisse vs Careprost: What’s the Real Difference?

When it comes to growing longer, thicker eyelashes, Latisse, a prescription eyelash growth serum approved by the FDA for cosmetic use. Also known as bimatoprost 0.03%, it’s the original product that started the eyelash enhancement trend. Careprost, a generic version of the same active ingredient, bimatoprost, originally developed as an eye pressure medication. Also known as bimatoprost 0.03%, it’s sold as a cheaper alternative, often imported from overseas pharmacies. Both contain the same active ingredient—bimatoprost—but that’s where the similarities mostly end.

Here’s the thing: Latisse comes in sterile, single-use applicators designed specifically for eyelash application. It’s packaged to avoid contamination, and the concentration is tightly controlled. Careprost, on the other hand, is usually sold in larger bottles meant for glaucoma treatment. People use it for lashes by transferring drops to a clean applicator—but that’s where risks creep in. Without proper sterile technique, you could introduce bacteria into your eye, leading to infections or irritation. Some users swear by Careprost because it costs a fraction of Latisse. Others report uneven results, faster depletion, or redness because the formulation isn’t optimized for cosmetic use.

The FDA hasn’t approved Careprost for eyelash growth, which means it doesn’t go through the same safety testing for that use. Latisse has clinical data showing consistent results over 16 weeks, with side effects like eye redness or darkening of the eyelid skin clearly documented and monitored. Careprost? Most of the data comes from anecdotal reports and off-label use. If you’re looking for reliability, Latisse wins. If you’re trying to save money and are comfortable managing risks, Careprost might seem tempting—but you’re trading convenience for control.

There’s also the issue of where you buy it. Latisse requires a prescription from a licensed provider, so you know what you’re getting. Careprost is often sold online without a prescription, through unregulated vendors. You might get a real product—or you might get something mislabeled, expired, or even counterfeit. That’s not just a waste of money—it’s a health risk.

Neither product works overnight. Both take about 8 to 12 weeks to show noticeable results, and if you stop using them, your lashes will return to their original state. But the difference isn’t just about speed—it’s about safety, consistency, and trust. One is a regulated medical product. The other is a repurposed drug with no quality guarantees for cosmetic use.

Below, you’ll find real comparisons from users who’ve tried both, breakdowns of side effects, cost-per-use calculations, and tips on how to use either safely—if you choose to go that route. No fluff. Just what works, what doesn’t, and what you need to know before you start.
