After receiving filler injections, some patients have minor, temporary side effects where they were injected. They may have redness, swelling, lumps, tenderness, bruising (occasionally) and vascular complications
Most of these side effects tend to clear within 7 to 14 days — if not earlier.
Serious side effects are more likely when the person injecting the filler does not have adequate medical training and experience. To protect yourself, you should never get filler injections in a non-medical setting, such as a non-medical spa, salon, or someone’s home. When fillers are injected in a non-medical setting or by an inexperienced provider, reports of more serious side effects increase dramatically.
