Bar Refaeli -- The First Post-Surgery Bikini Sesh

Guess Bar Refaeli is feeling better after going under the knife ... 'cause hours after she had a mole surgically removed from her torso, the supermodel was galavanting around in her bikini.

Bar originally posted a pic in a doctor's office on November 12 -- with the caption, "Goodbye beauty mark." It's unclear why the 28-year-old had the mark removed.

But hours after the procedure, Bar posted another couple of shots ... showing her running around the beach in a bikini with a bandage on the spot where her mole used to be.

Supermodels -- they even make recovering from surgery look easy.
