What filler dissolving is
Hyaluronidase (brand names Hylenex, Vitrase) is an enzyme that digests hyaluronic acid, the material in Juvéderm, Restylane, RHA and Revanesse fillers. Injected into the area, it breaks the gel down within hours; swelling settles over a day or two and the result is visible at about 48 hours.
People search for this as "filler dissolver", "lip filler removal", "dissolving lip filler", "hyaluronidase injection" or "filler reversal". It is the same treatment. It works only on hyaluronic acid fillers; Sculptra, Radiesse, silicone and fat cannot be dissolved.
Dr. Toma uses it for three reasons: to correct a problem (migration above the lip line, lumps, a bluish Tyndall tint under the eyes), to reset before planning fresh work, and urgently for a suspected vascular occlusion, which is why hyaluronidase is kept available whenever hyaluronic acid filler is placed.
What can and cannot be dissolved
If you do not know which filler you had, a small test area is treated first.
| Filler type | Examples | Can it be dissolved? |
|---|---|---|
| Hyaluronic acid (HA) | Juvéderm, Restylane, RHA, Revanesse, Belotero | Yes, usually in 1 to 2 sessions |
| Calcium hydroxylapatite | Radiesse | No; it is absorbed gradually over many months |
| Poly-L-lactic acid | Sculptra | No; the collagen it stimulates is your own tissue |
| Permanent fillers | Silicone, PMMA (Bellafill) | No; a surgical opinion is needed |
| Fat or allograft matrix | Fat transfer | No |
Denser, more cross-linked HA (such as Voluma) can need more enzyme or a second session than softer lip gels.
Small, diluted doses can soften a specific lump or a migrated edge while keeping the rest of the result. Full reversal uses a higher dose across the area.
True allergy to hyaluronidase is rare but possible. A forearm patch test is offered about 20 minutes before treatment, and is advised if you have a bee or wasp venom allergy.
Common reasons
| Problem | Typical approach |
|---|---|
| Lip filler migration (above the lip border) | Targeted dissolve; refill after about 2 weeks if wanted |
| Over-filled or uneven lips | Full or partial dissolve, 1 to 2 sessions |
| Under-eye puffiness or bluish tint (Tyndall effect) | Low dose, often one session |
| Lumps or nodules | Small diluted dose into the lump |
| Old filler before new planning | Full reset, then a plan at the two-week review |
| Suspected vascular occlusion (emergency) | High-dose hyaluronidase at once, repeated as needed, with emergency care |
Dissolving is quoted separately from any new filler.
Who it is for
- Lips that look migrated, heavy or "ducky"
- Lumps, asymmetry or a bluish tint from a previous filler
- You had filler elsewhere and want a clean start
- You want less, not more
- Known allergy to hyaluronidase (patch test first if you have a bee or wasp venom allergy)
- Active infection at the site
- Pregnant or breastfeeding
- Non-HA fillers (Radiesse, Sculptra, silicone)
- Dissolve Radiesse, Sculptra, permanent fillers or fat
- Remove your own natural hyaluronic acid permanently; the skin replaces it within days
- Guarantee a one-session result for dense, old product
How much does filler dissolving cost?
Priced per session, with a lower rate for a small targeted area, stated as a minimum fee with the dates it is in effect. When a planned adjustment of Dr. Toma's own work is part of your written plan, it is covered by that plan. Everything is in writing before treatment.
Prices are confirmed at consultation and stated with their effective dates. Any offer carries its start and end dates. How pricing works.
What happens, step by step
- ConsultationIdentify the filler
What was injected, where and when. If unknown, a small test area is treated first.
- Day 0Patch test and treatment
Optional forearm patch test, about 20 minutes. Then diluted hyaluronidase is injected into the filler and massaged. About 30 minutes.
- Hours 1 to 24Breakdown
The gel softens within hours. Expect swelling; the area can look worse before it looks better.
- Day 2 to 3Result visible
Swelling settles and the result shows. Photos compared.
- Week 2Review and refill
A second session if dense product remains, or new filler once the area has settled, if you want it.
Risks and side effects
Common: swelling for one to three days, bruising, tenderness. Uncommon: temporary loss of some natural volume, because the enzyme also breaks down your own hyaluronic acid; it rebuilds within days. Rare: allergic reaction, including anaphylaxis, which is why a patch test is offered and emergency medication is available.
