Regalo is just a gift.
Pasalubong is gift you give after coming back from somewhere, or visiting from far away. So, if you go to Paris and buy a little statue of the Eiffel Tower to give to your mom, that would be pasalubong. If you are visiting the Philippines from the US and bring chocolates for your cousins, that would be pasalubong.
