A facial muscle and mouth exerciser for maintaining the health, appearance, and flexibility of the facial and mouth muscles, and useful as a therapeutic device to prevent disfigurement of damaged tissues that may result from burns or cuts about the face and mouth, formed of two similar, all plastic molded components arranged in reciprocal sliding relationship for relative movement between an extended and retracted position whereby the relative movement of the components is normally biased toward the extended position and resisted toward the retracted position by an elastic band or spring resistant member.
