We were descending on the BDEGA 3 RNAV arrival in the vicinity of BDEGA. We were given a descend via clearance except to maintain 11;000 ft. As we were descending below 13;000 ft. we simultaneously encountered wake turbulence from an A380 as ATC amended our altitude to 12;000 ft. and cautioned us for wake turbulence. We reported that we experienced the wake turbulence and were then given a further descent which we denied and remained level at 12;800 ft. to allow for more separation. We were then issued a pilots discretion descent. I called back to check on crew and passengers. No injuries reported; however [a] Flight Attendant mentioned to the First Officer as she was leaving the aircraft that she may have re-injured her tail bone.This is a constant problem going into SFO. There are certain airports we operate into (SFO; LAX) where wake turbulence is a constant problem and an ongoing threat. Our air traffic controllers do an excellent job with the resources given and the volume of traffic they have to manage; however I would like to see some additional arrival spacing from heavies when flying into these airports. As a side note; I think the FAA needs to re-evaluate the categorization of the 757 and solicit feedback from pilots that deal with it on a daily basis.
Air carrier Captain reported encountering wake turbulence on arrival into SFO in trail of an A380. Reporter stated would like to see more separation from heavy aircraft; and further recommended re-evaluating the B757.
