After the treatment, the patient may experience some minor swelling, redness, and bruising, but this should subside within a few days. Also it is common for the patient to feel ‘lumps’ in the treated area. This may resolve with massage or will subside as the filler integrates with the tissue. In cases of vascular occlusions or if you are simply not satisfied with the appearance, the treated area can be reversed using Hyaluronidase.
