Rejuvapen makes use of a microneedling device to stimulate collagen and elastin production. The procedure can be used for skin on the face, neck and abdomen. A Rejuvapen handpiece, containing a cartridge with nine small needles, is glided gently across the surface of the skin. Rejuvapen triggers the body’s natural healing abilities and stimulates collagen production. Peptides and growth factors are also applied during the procedure to maximize effectiveness.
