In a brief post to Instagram, the actress wrote of a "season for healing" in apparent reference to the Oscars incident.
Her husband, Will Smith, was condemned by the awards organisers for hitting Rock.
He apologised on Monday, calling violence "poisonous and destructive".
The incident Sunday night happened just before Smith won the Oscar for Best Actor, when the comedian Rock was on stage to present the award for Best Documentary.
He made a quip about Pinkett Smith's shaved head, a result of the hair-loss condition alopecia.
