A skin raising suction device to maintain the skin with its underlying strata automatically lifted and stretched above the rest of the body has a hard cylinder, a piston-type dome and a bulging elastic belt integrally connecting the upper rims of the cylinder and dome, the cylinder having a frusto-conical inner wall narrowing toward its bottom to about the diameter of the dome; the belt having a volume and a resilient capacity to permit pushing it within the cylinder on depression of the dome together with it toward the bottom of the cylinder and the skin and a dynamic elastic memory and strength to lift automatically the dome with the skin and connecting tissues away from the body into the cylinder after release of the compression.
