Information about the procedure

Restoring volume and refining contours with hyaluronic acid — the result is immediate and reversible.

This information is for general guidance only and does not replace a medical consultation. The specific plan, technique, price, recovery and risks are determined after an in-person examination and an assessment of your anatomy, general health and expectations.

What it involves

Hyaluronic acid fillers replace lost volume and shape contours. Hyaluronic acid is a substance found naturally in the body’s tissues, and the body breaks it down over time.

With age, the face does not just sag — it loses volume. The fat compartments shrink and bone is resorbed. Filler restores some of this volume and often gives a more natural result than tightening the skin.

The great advantage of hyaluronic acid is that it is reversible. If the result is unsatisfactory or a complication occurs, it can be dissolved with an enzyme.

Types and approaches

Lips

Hydration, subtle volume and contour definition. The aim is lips that look like your own, not as though something has been added.

Cheeks and midface

Restoring structural volume, which supports the entire midface.

Nasolabial folds and marionette lines

Softening deep folds, most often combined with treatment of the cheekbones.

Tear trough

Smoothing the hollow under the eye. Technically one of the most demanding areas, requiring experience and the right product.

Chin and jawline

Improving the profile and defining the jawline without surgery.

Non-surgical nose correction

Straightening the profile or camouflaging a small hump. A higher-risk area that requires particular care.

Biostimulators

Products such as Profhilo do not add volume but improve skin hydration and quality.

Who it is suitable for

Suitable for

  • Volume loss in the cheeks and temples
  • Deep nasolabial folds and marionette lines
  • Thin lips or asymmetry
  • Poorly defined jawline or a weak chin
  • Wish for a result without downtime
  • Preference for a reversible procedure

Not suitable, or postponed, in cases of

  • Pregnancy and breastfeeding
  • Active infection, cold sores or inflammation in the area
  • Autoimmune disease in an active phase
  • Non-absorbable (permanent) filler previously injected in the same area
  • Taking anticoagulants that have not been discussed beforehand
  • Unrealistic expectations or a wish for excessive volume

Preparation

  • Stopping blood thinners and supplements a few days before the procedure, as agreed with your doctor
  • Avoiding alcohol for 24 hours beforehand
  • Preventive antiviral treatment before lip treatment if you have frequent cold sores
  • Scheduling the treatment at least two weeks before an important event
  • Telling us about all previous facial procedures and products injected into the face

How it is performed

The procedure is performed as an outpatient treatment using an anaesthetic cream, and most fillers also contain a local anaesthetic. It takes 20–45 minutes.

A needle or a cannula is used, depending on the area. In certain areas, a cannula reduces the risk of vascular complications.

The result is visible immediately, but it is masked by swelling for the first few days.

Recovery

  • The first few hoursSwelling, redness and sometimes small bruises. In the lips, swelling can be considerable and make them look overfilled.
  • 24–48 hoursSwelling peaks, especially in the lips. Avoid saunas, sunbeds, strenuous exercise and massaging the area.
  • 3–7 daysThe swelling subsides and any bruising fades. The actual result starts to show.
  • 2 weeksThe product integrates into the tissue. Follow-up appointment, with a touch-up if needed.
  • 6–18 monthsThe filler gradually breaks down, at a rate that depends on the area and the type of product.

Pain and discomfort

Discomfort is moderate and short-lived. The lips are the most sensitive area, so an anaesthetic cream is applied there. Most fillers contain lidocaine, which dulls sensation after the first needle prick. The cheeks and jaw are better tolerated.

Risks and complications

Every intervention carries risks. Listing them does not mean they are expected to occur — it allows you to make an informed decision.

  • Swelling and bruising — expected, not a complication
  • Asymmetry or unevenness, usually correctable
  • Nodules or lumps under the skin
  • Prolonged swelling, especially under the eyes
  • Cold sore outbreak in those prone to them
  • Inflammatory reaction or delayed-onset swelling — rare
  • Vascular complication with compromised blood supply to the skin — rare but serious, and requires immediate treatment
  • Very rarely: visual impairment after injection into high-risk areas

Results and longevity

How long the result lasts depends on the area and the product: lips usually 6–9 months, cheeks and jaw 12–18 months; the tear trough varies widely.

The result is broken down gradually rather than disappearing all at once.

Reversibility is a key advantage — if needed, the product can be dissolved with hyaluronidase.

Frequently asked questions

Will I look unnatural?
No, if the amount is matched to your anatomy. An unnatural look comes from excessive volume and from filling areas that do not need it, not from the product itself.
Can it be removed if I don’t like it?
Yes. Hyaluronic acid can be dissolved with an enzyme — hyaluronidase. This is one of the most important advantages of this type of filler.
How long does the effect last?
It depends on the area and the product — usually between 6 and 18 months. Filler in the lips breaks down fastest because of their constant movement.
When will the lip swelling go down?
Most of it within 2–3 days, and completely within a week. For the first 48 hours, the lips look considerably fuller than the final result.
Can it be combined with botulinum toxin?
Yes, they are very often done together. Botulinum toxin acts on the muscle, filler on volume. They do different jobs.
Are fillers dangerous?
With the right technique, a high-quality product and a sound knowledge of anatomy, the risks are low. The most serious complication is vascular, which is why the choice of injector matters more than the choice of product.
