We use the so-called Ultraformer at the HAUT- UND LASERZENTRUM AN DER OPER to smooth loose skin on the upper arms, stomach, back and thighs. This non-invasive tightening method works using ultrasound energy. The highly focused ultrasound penetrates the lower dermis without damaging the skin surface. The resulting short-term, controlled heat of 65 to 70 degrees Celsius triggers both an instantly visible, as well as long-term tightening effect in the connective tissue. In addition to shrinking the collagen fibres, the reason for this is the stimulation of the fibroblasts, which provide a significant boost to collagen and elastin production. One treatment is generally sufficient. There may be minimal redness, slight swelling or temporary sensitivity to touch straight afterwards. A final result is expected after around 180 days.
