What is a hyaluronic acid filler?
Filler is a gel of hyaluronic acid, a substance naturally present in the skin, which holds water. Injected in small amounts under the skin, it restores volume, redraws a contour or fills a hollow. It is absorbable: the body gradually eliminates it, which allows the result to evolve and, if needed, to be dissolved with an enzyme, hyaluronidase.
Which areas can be treated?
The most requested are the lips, nasolabial folds, cheekbones, chin, jawline, tear trough (hollow under-eyes) and temples. The nose can be touched up temporarily (see the medical rhinoplasty page). Each area is approached in terms of facial harmony: volume added at one point can change the whole, hence the value of a global, gradual plan.
Full face, lips, under-eyes
Cheekbones, contour, chin, tear trough: a global protocol can be considered to harmonise the face. For the lips, we look for volume and hydration while respecting proportions. For hollow or pigmented dark circles, treating a tired look often combines filler, PRP and sometimes laser, depending on the diagnosis.
How a session goes
The session follows a consultation: examination of the face, discussion of expectations, choice of product and technique. An anaesthetic cream may be applied, and some products contain a local anaesthetic. Injections are made with a fine needle or a cannula, in small amounts, with regular reassessment. Afterwards, swelling, redness or small bruises are possible for a few days; return to activities is quick.
How long does the result last?
Duration varies with the product, area and person: from a few months to over a year. Very mobile areas (lips) tend to be absorbed faster than less mobile ones. The result is maintained with small touch-ups, without overcorrecting. The exact duration becomes clear over the touch-ups, as each person absorbs the product at their own pace.
Portable ultrasound: extra safety
The clinic has a Clarius L20 HD3 portable ultrasound. In certain vascular-risk areas (nose, glabella, folds, temples), it allows vessels to be located before injection and the technique to be adapted. It also helps locate a filler already injected, for example to understand a lump or asymmetry. The examination is painless, without radiation, and complements the clinical examination, depending on the indication.
Risks, precautions and safety
Common effects are benign: swelling, redness, bruising, small irregularities that can be corrected. More rarely, an infection or a nodule. The most feared complication is occlusion of a vessel, rare, linked to injection in a high-risk vascular area (nose, glabella, folds): it requires knowing the anatomy, working in small doses and having hyaluronidase available. Filler is avoided during pregnancy and breastfeeding.
A filler too bulky or badly placed: what to do?
Hyaluronic acid is reversible: a lump, asymmetry or excessive volume can be corrected with a hyaluronidase injection, which dissolves the product. Before dissolving, ultrasound can help locate the filler. This management, including for fillers done elsewhere, is described on the filler dissolution page.
Avoiding the "done" look
Successful fillers go unnoticed. For that: small quantities, areas chosen for harmony rather than volume, spaced touch-ups, and a look at the face in movement, not only at rest. Too much product, or product in the wrong place, gives a puffy or frozen look. If that has already happened, hyaluronic acid can be dissolved (see the filler dissolution page).
Preparing well, and what to do afterwards
Report treatments that thin the blood and your history of herpes: for the lips, preventive treatment can be discussed. Avoid alcohol the night before and, after the session, intense heat (hammam, sauna), intense sport and massage of the area for 24 to 48 hours. Swelling is normal in the first days; sharp pain, white or purplish skin or visual disturbance require calling immediately.
Filler, skinbooster, Sculptra: how to tell them apart
Filler fills a volume or redraws a contour. Skinbooster hydrates the skin without changing volumes. Sculptra stimulates collagen production gradually. The three meet different needs and are often combined: the examination decides the order and dosage.
