Skin redness, rosacea and/or discreet erythema afflicting a mammalian, notably human patient, are therapeutically treated by administrating to such patient a therapeutically/cosmetically effective amount of at least one CGRP antagonist, advantageously in combinatory immixture with at least one antagonist of a neuropeptide other than CGRP, e.g., a substance P antagonist, and/or at least one inflammation mediator antagonist.
