Different products behave differently
Filler choice depends on the treatment goal, the tissue and the depth of placement. A product suitable for structural support is not automatically suitable for mobile or delicate tissue. Brand alone does not replace clinical judgement.
Previous filler changes the assessment
Tell the doctor what was injected, where and when. Persistent filler, migration, nodules, swelling or altered anatomy may require investigation, observation or a different plan before adding more volume.
Understanding risk
Common effects include swelling, bruising, tenderness and temporary asymmetry. Rare vascular complications can threaten skin or vision and require immediate recognition and treatment. Patients should receive clear warning signs and an emergency contact pathway.
Frequently asked questions
01How many syringes do I need?
That cannot be decided from a trend or package. The amount follows the anatomical goal and may be staged.
02Can hyaluronic-acid filler be dissolved?
Many hyaluronic-acid fillers can be treated with hyaluronidase, but dissolving also has risks and should be medically assessed.
03Can filler move?
Apparent migration, swelling, product persistence and placement can all change contours. Examination is needed before assuming the cause.
