Grammar Police: If something is made by an artisan, is it called "artisan" or "artisanal?"?

I’m on some craft pages in Facebook, and people refer to their items as (for example) “artisan soaps” meaning handmade, fine soaps. I think the proper phrase should be “artisanal soaps.”

Can you please help me? If something is “special” would you refer to it as “artisan” or “artisanal?”
