Does Latisse (bimatoprost) “expire” as a product name?
Latisse is the brand name for prescription bimatoprost solution used to treat hypotrichosis (inadequate eyelashes). Brand drug protection doesn’t behave like a simple “expiration date” for the product itself; what matters is when exclusivity and patents end, which can allow cheaper generic or authorized versions to enter.

Is there an expiration date on the physical Latisse bottle?
If you mean shelf-life rather than legal exclusivity: every medication bottle has an expiration date set by the manufacturer, and you should not use the product after that date. (This is separate from patent/exclusivity timelines.)
How to tell which “expiration” you’re asking about
If you’re deciding whether you can switch to a cheaper option, the relevant question is patent/exclusivity (timelines vary by country and specific protections). If you’re deciding whether your bottle is still usable, the relevant question is the printed expiration date and storage instructions on your medication.
Quick check: which country matters?
Patent and exclusivity rules differ by country, so tell me where you are (US, UK, Canada, etc.) and whether you mean legal availability or the shelf-life date on the bottle.
