Can I get renova (tretinoin) in france?

Not legally. Renova is a us brand of tretinoin. France, as does the entire european union, has strict rules against importing non-eu manufactured prescription medications. Honestly, I am not a huge fan of Renova and you can get regular tretinoin in france very easily. Be careful with sun-exposure and use a good sunscreen with it. Start of at a low-dose until your skin becomes tolerant and ten increase it.
