As Plasma Skin Tightening is more than a simple tightening treatment, skin is actually removed, so the effects should last as long as they would with invasive surgery. Like all surgical and cosmetic procedures, the effects of plasma treatment are not entirely permanent as it does not stop any further ageing. But, the positive results should last you years depending on the area treated. The positive effects of treatment will be noticeable immediately after the first treatment, but the best results will be seen after 8-12 weeks. For some, an additional treatment may be required for maximum results.
