Can Filler Be Dissolved? A Hyaluronidase Guide

What is hyaluronidase?

Hyaluronidase is an enzyme group that breaks down hyaluronic-acid chains. Naturally present in the human body. Treatment forms include Hylase, Hylenex, Liporase.

When it's needed

Vascular occlusion (emergency)

Applied within minutes when vessel blockage signs appear (pallor, delayed cap-refill, severe pain, mottling). Hyaluronidase must be available on-site for every filler session.

Patient dissatisfaction

If the patient is unhappy or accidental over-correction occurs, dissolving is offered.

Tyndall effect

Bluish hue in thin-skinned zones (tear-trough) from too-superficial filler — reversed with hyaluronidase.

Asymmetry

Targeted dissolving on the over-corrected side.

How it's done

1. Skin test (allergic-reaction screening, especially for animal-derived forms)
2. Targeted injection
3. 24–72 hours wait; second session if needed

Side effects

• Local swelling, tenderness (transient)
• Allergic reaction (rare)
• Some adjacent native HA may be temporarily affected — restored quickly

Bottom line

Reversibility is one of HA filler's strongest safety properties. Hyaluronidase is critical for both complication management and patient satisfaction. Always available on-site.
