A nasal pressure stabilizing device for a subsea mask includes two pockets. Each capsular bag is provided with an opening and a bottom area corresponding to the opening, and each bottom area is pre-formed into a first shape with a plurality of continuous bending parts and is located at a first position far away from a nose wing of a user. When the two fingers of the user apply force inwards towards the bottom areas from the openings of the two bags respectively, each bottom area can be stretched and deformed into a second shape and is located at a second position close to the nose wing of the user. When the applied force is released, each bottom area can recover automatically or return to the first position under the action of an outward thrust force and recover to the first shape.
