Filler dermatology clinics compared by area

Updated 2026-11-08

Filler is a procedure that injects a gel-like substance under the skin to fill hollow areas or refine contours. The most widely used is hyaluronic acid filler, made of a substance naturally present in the body; there are also products made with calcium-based ingredients or biodegradable polymers. The firmness of the product and the injection depth differ by area, such as the nasolabial folds, under the eyes, the forehead, the nose and the chin.

Hyaluronic acid filler can be dissolved with an enzyme called hyaluronidase, so there's a way to reverse it if you're unhappy with the result or a problem occurs. Fillers made of other ingredients, by contrast, don't respond to this enzyme. How long filler lasts varies widely with the product, the area and lifestyle, and is generally described across a broad range from several months to over a year.

Checklist for choosing a clinic for Filler

  1. Product ingredient and volume Whether it's hyaluronic acid, a calcium-based product or a polymer affects how long it lasts and how it can be reversed. When you consult a clinic in your area, confirm the ingredient and the volume per area, and keep a written record with the product details; it helps if you later see another clinic.
  2. Whether a dissolving agent is on hand It's worth asking whether hyaluronidase, which dissolves hyaluronic acid filler, is always kept in stock, because using it quickly when a vascular complication is suspected is central to the response. Before deciding on a clinic in your area, see whether they can answer this question right away.
  3. Explanation of high-risk vascular areas The areas between the brows, the nose, the forehead and around the nasolabial folds lie close to blood vessel pathways and are considered relatively high-risk for complications. If you want these areas treated in your area, ask whether a needle or a blunt-tipped cannula is used and how the risk is reduced.
  4. Share your treatment history Leftover filler from earlier sessions, or substances of unknown composition, can overlap with new filler and cause lumps or inflammation. Telling a clinic in your area at the first consultation when and where on your face you were treated, and any product details you know, helps with planning.
  5. Aftercare contact arrangements Ask for the number to call right away if pain worsens or skin color changes, and how they respond outside opening hours. If you're having the procedure in your area, also consider how long it would take to get back to the clinic from home or work.

Warning signs to watch for

  1. Skin turning pale or purple If the skin blanches right after injection, or a net-like purple discoloration appears within days with worsening pain, it may signal a blocked blood vessel. Contact the clinic in your area that treated you immediately and get seen.
  2. Blurred or lost vision Blurred vision or loss of sight in one eye after injections between the brows, in the nose or on the forehead is very rare but an emergency. Because time determines the outcome, notify the clinic that treated you and at the same time head to the emergency room you can reach fastest in your area.
  3. Procedures that won't disclose ingredients Avoid anyone who is evasive when asked for the product name or ingredients, and injections given outside a medical institution. Substances of unknown origin can't be dissolved and may cause inflammation long afterward, so if you receive such an offer in your area, it's safer to stop.
  4. Swelling or lumps weeks later Swelling and bruising right after the procedure are common, but red swelling or a hard lump appearing weeks to months later may be a delayed inflammatory reaction. When you see a doctor in your area, tell them when you had filler and which product it was.

Frequently asked questions

Can filler be dissolved?

Hyaluronic acid filler can be dissolved, but fillers of other ingredients are hard to dissolve. Injected hyaluronidase breaks it down, though rare allergic reactions can occur. That's why you should confirm the ingredient before treatment in your area.

How long does filler last?

It varies widely by product and area. Mobile areas like the mouth tend to absorb faster, still areas to last longer; generally several months to over a year is quoted. When consulting in your area, ask about your product and area.

How long do bruising and swelling last after filler?

Bruising and swelling usually settle within a few days to 1–2 weeks. Needle bruising and injection-site swelling are common, but worsening pain or color change is another matter. Before an important event, schedule treatment in your area well ahead.

What's the difference between a needle and a cannula?

A needle suits precise points, while a cannula suits even spreading over wider areas. A blunt-tipped cannula pushes vessels aside to lower risk but can't fully prevent vascular complications. Ask a clinic in your area which tool they use and why.

How is filler different from Botox?

Filler adds volume; Botox reduces muscle movement. Filler is mainly for areas hollow at rest, Botox for lines deepening with expression, and both are sometimes combined. When consulting in your area, first describe the change you want.

Final notes

Because filler results show immediately, product choice and emergency readiness matter. When comparing clinics in your area, check whether they disclose ingredients, keep a dissolving agent on hand and have aftercare contact arrangements. If you have had previous procedures or have allergies, discuss them fully with the doctor before treatment.
