The first publications regarding aesthetic treatments with polydioxanone threads (PDO) date to 2015 and were preceded by the establishment of this polymer use for surgical sutures as a safe, less inflammatory option that brings superior final aesthetic-functional results. The present article describes a series of five patients that received PDO thread lifting for abdominal periumbilical laxity.

Histological data on microscopic treatment zones are essential for evaluating procedure safety and effectiveness. To date, no studies have histologically compared low-temperature plasma with other techniques. In this study, two square areas on the patient's abdomen, referred to as area A and area B, were with low-temperature plasma and fractional CO2 laser, respectively. A biopsy was taken immediately after treatment. When applied to thinner skin regions, plasma technology appears to result in fewer complications, a faster recovery, and fewer side effects during the application period. However, further studies are needed to confirm these findings.
