When do you need a filler dissolving treatment?

There are some cases when you might want to dissolve the filler. These are:

  • Filler spreads to other areas of the skin
  • Lumps have formed near the treated area
  • An asymmetrical result after getting dermal fillers
  • Allergic reactions such as swelling in the treated area.
  • Overfilled area
  • Infection after filler

What is the filler dissolving procedure?

Filler dissolving is a process in which hyaluronidase enzyme is injected in the area treated with dermal fillers. The procedure is very simple and quick to perform. Dr Kernohan may use 1 to 4 injections of Hyalase into the area where you want to dissolve the filler. The total time of this procedure is up to 10 minutes.

What is Hyalase?

Hyalase consists of an active ingredient which is a hyaluronidase enzyme that can be used to break down the hyaluronic acid filler. It takes up to 2 weeks to get desirable results and you may need to repeat the procedure. You may also experience slight vasodilation, redness, and erythema after the treatment. It is important to provide an appropriate dose of Hyalase injection into the treated area because it can damage a large amount of hyaluronic acid.

How does Hyalase treatment work?

During Hyalase treatment, Dr Kernohan may perform a skin patch test. Then, he might administer an anaesthetic to make the treatment more comfortable for you. Then Hyalase is injected into the desired areas. Make sure to schedule a check-up two weeks after the procedure to check dose administration and results.  Sometimes, you may need additional dissolving treatment, so you have to repeat the procedure. Dr Kernohan will tell you if additional sessions are required.

Good candidates for Hyalase treatment

To find whether Hyalase treatment is suitable for you or not, Dr Kernohan might do a patch test. The skin patch test is performed twenty minutes before the procedure. During this test, a little amount of Hyalase is injected into the skin and see the results. If it causes any kind of reaction and the test is positive, then you are not a suitable candidate for Hyalase treatment. If the test is negative, then Dr Kernohan can dissolve the filler with the help of Hyalase injections.

Generally speaking, all patients getting filler injections and desiring to reverse the effects are potential candidates for this treatment.
