A lip suction device. A rigid hollow form has an opening at a first end of the rigid hollow form and a cavity therein extending from the first end to a second end of the rigid hollow form. The rigid hollow form has an outer surface and a thickness at the opening between the outer surface and a surface of the cavity. The opening has an edge with a rounded shape, across the thickness at the opening, which is configured to form a substantially air-tight seal between a user's face and the edge when the rigid hollow form is pressed against the user's face near the user's lips. The rigid hollow form is configured so that when the user draws air into the user's mouth after forming a substantially air-tight seal, the user's lips are drawn into the rigid hollow form towards the second end of the rigid hollow form.
