As Fibroblast is more than a simple tightening treatment (skin volume is actually reduced), the effects should last as long as they would with invasive surgery. Like all surgical and cosmetic procedures, the effects of fibroblast are not entirely permanent as it does not stop any further aging, but the positive results should last years depending on the area treated. The positive effects will be noticeable immediately after the first treatment, but the final results will be seen after 8 weeks. For some, an additional treatment may be required after 8 weeks for maximum results. Additionally, there are lifestyle factors that can interfere with the treatment results, such as smoking, alcohol consumption, and prolonged sun exposure.
