As found on MSDN, you can use SQL Server Express Edition in production environment but you have to consider some technical limitations:

• maximum of 1 processor, up to 4 cores allowed
• maximum memory utilized (per instance of SQL Server Database Engine) 1GB
• maximum relational Database size 10GB
