What Is Hyaluronidase and When Is Filler Dissolving Considered?

Hyaluronidase is an enzyme a physician may use in selected situations to accelerate breakdown of hyaluronic-acid (HA) filler. Not every filler can be dissolved this way, and not every aesthetic concern requires hyaluronidase.

Which fillers can be dissolved?

Hyaluronidase acts on hyaluronic-acid fillers. Materials such as calcium hydroxylapatite (CaHA) or poly-L-lactic acid (PLLA) do not respond in the same way, so identifying the product is important when possible.

Why might elective dissolving be considered?

Excess volume, unwanted contour, asymmetry or superficial product placement may lead to consideration of elective correction. Early swelling can also alter appearance, so timing and examination matter.

Is an emergency the same as elective dissolving?

No. Increasing severe pain, marked pallor or color change, cool skin, impaired capillary circulation or visual symptoms after filler should not be managed as a routine cosmetic correction. They require urgent medical assessment.

Is one session always enough?

No fixed number applies to every patient. Product amount and characteristics, anatomical area, time since injection and the intended degree of correction can affect the plan.

Are there risks?

Hyaluronidase is a medical treatment. Swelling, redness, tenderness and hypersensitivity reactions can occur, so the decision should follow medical history and clinical assessment.
