At Skin & Tonic our focus is on offering non-invasive, safe, and quick skin rejuvenation and tightening treatments with pleasing results. PDO threads are one such reliable and painless treatment that gives you long-lasting skin tightening results. PDO stands for polydioxanone, and the PDO threads are medical-grade threads made of proteins and are thinner than hair. The insertion of threads results in a natural response that improvesthe flow of blood while stimulating the generation of skin health proteins such as collagen and elastin. PDO thread insertion also encourages the production of hyaluronic acid that is present in the dermal layers of the skin and helps maintain the volume and texture of the skin.
