As with all injections, there is the risk of bruising, bleeding, bruising, itching, swelling, tenderness, discomfort and redness. These side effects would subside in 2-6 days.
A delayed side effect of small bumps appearing under the location of the skin being treated may occur. These may or may not be visible, although will be noticeable when pressing the treated area, and should be reported to the practicing clinician.
Such side effects can be minimised by ensuring that you select a reputable clinic and practitioner who has the necessary experience and training in Sculptra.
