When should a filler be dissolved?
Asymmetry, excess volume (lips too full, cheekbones too prominent), palpable bumps or nodules, a bluish tint under the skin (Tyndall effect), product that has migrated, or simply a result you do not like. Dissolution is also used to treat certain complications.
What dissolution can and cannot do
Hyaluronidase acts only on hyaluronic acid, including that of skinboosters. It does not affect Sculptra, non-absorbable products or fat. It can also dissolve a little of the skin's natural hyaluronic acid, temporarily. Depending on the amount of product, one session is sometimes enough; in other cases several are needed, with a check between each.
When to do it
The doctor decides on the right time after examination. They judge whether the initial swelling should first settle or whether the result is established. If there is significant discomfort or a complication, there is no waiting.
How it goes
If the filler was placed elsewhere, the simplest thing is to talk first to the practitioner who did it: they know the product and technique. You can also ask Dr Zahid for an opinion. The consultation serves to examine the face, identify the product (bring the card or information if you have it) and define the area to treat. Hyaluronidase is then injected in small amounts. The effect appears gradually over 24 to 48 hours, and a check then decides on another session or a touch-up.
Locating the filler with ultrasound
Before dissolving, it helps to know where the product is, in what quantity and at what depth. The clinic's portable ultrasound (Clarius L20 HD3) allows the injected hyaluronic acid to be visualised and distinguished from oedema, inflammation or another cause of a lump. Areas and doses can then be better targeted. This examination is not always necessary: the doctor decides at the examination.
Emergency: sharp pain after a filler
Sharp pain, skin turning white or purplish, or visual disturbance after an injection can signal occlusion of a vessel. It is an emergency: contact the clinic or emergency services immediately. Hyaluronidase is part of the treatment, without delay.
Risks and precautions
Temporary swelling, redness and bruising are possible; dissolution may be incomplete, or temporarily excessive. Allergy to hyaluronidase is rare: report any allergy and current treatment. The treatment is postponed in case of infection or active herpes in the area, and, depending on the situation, pregnancy or breastfeeding.
