A dispenser for discharging a pharmaceutical or cosmetic medium having a discharge head with a discharge opening, a container for storing the medium prior to discharge, an elastically deformable outer container, and a dimensionally flexible inner container arranged in an interior of the outer container. A ventilation channel is provided, through which the interior of the outer container is connected to an environment for pressure compensation by compensating air. The ventilation channel is delimited in at least some regions by a self-adhesive label, or the ventilation channel has a self-adhesive label and has a gas-permeable surface portion. The gas-permeable surface portion is arranged in the ventilation channel or on one of the ends of the ventilation channel, such that the air passing through the ventilation channel also passes through the gas-permeable surface portion.
