The invention relates to a dispenser for drip-dispensing a sterile liquid product containing a surfactant. The dispenser comprises a reservoir (1) comprising a wall (2) that is designed to deform when pressure is applied to the reservoir by a user of the dispenser and to spontaneously return to its original shape upon release. The reservoir (1) further comprises a flexible bag (3) in the internal space defined by the wall (2) thereof, for holding the liquid product. The dispenser comprises an air inlet means (14) for letting air in between the wall (2) of the reservoir (1) and the flexible bag (3), and a head that comprises a drip end piece (7) comprising a dispensing opening. The dispenser also comprises a hydrophilic sterilizing microporous membrane (10) which is arranged so that the liquid from the flexible bag passes therethrough on the way to being dispensed. The dispenser comprises a device that is configured to keep the membrane (10) wetted with the liquid product from the reservoir (1) between two instances of the liquid product being dispensed. The microporous membrane (10) is selectively permeable to the liquid such that it prevents air from re-entering the flexible bag of the reservoir when the dispenser returns to its original shape. The volume of liquid dispensed is compensated for by the ingress of a corresponding volume of air between the wall (2) of the reservoir (1) and the flexible bag (3) via the air inlet means (14).
