A subcision device having a closed state and a cutting state, the subcision device comprising:

a first element having a blunt surface and defining a longitudinal axis;
and
a cutting element coupled to the first element via a hinge, the cutting element including a shaft and a blade,
wherein, in the closed state, the blade is substantially within an outer perimeter of the first element,
wherein, in the cutting state, the blade is exposed and extends laterally from the shaft away from the longitudinal axis of the first element and outside of the outer perimeter of the first element with the blade rear-facing and forming an acute angle with the longitudinal axis, and retraction of the subcision device in the cutting state is configured to cut a tissue with the blade, and
wherein rotation of the cutting element relative to the first element about the hinge is configured to transition the subcision device between the closed state and the cutting state.
