Hyaluronic acid is a sugar the skin already contains. Cross-linked into a gel and placed under the skin, it restores volume that has been lost and softens folds that have set. It is a medical procedure with real risks, not a beauty treatment.
The right candidate has a specific, describable concern — a fold, a hollow, a lost contour — rather than a wish to look like someone else. Volume is replaced where it has gone, not added everywhere it can be.
Fillers are not given during pregnancy or breastfeeding, over active acne, cold sores or infection, or where there is a known allergy to hyaluronic acid or to lidocaine. Blood thinners and some supplements raise the bruising risk and are reviewed beforehand, not ignored. Anyone wanting permanent filler is refused and offered a surgical opinion instead.
The result depends far more on where the product is placed and how much is used than on the brand on the box.
Hyaluronic acid fillers differ in how heavily they are cross-linked and how firm the gel is. Softer gels for lips and fine lines, firmer ones for deep planes over bone. Most contain lidocaine, which makes the injection more comfortable.
A needle is precise for lips and fine folds; a blunt cannula reduces bruising and lets the product be laid in a single track. Deep placement over bone supports; superficial placement refines. The plane is a clinical decision, not a preference.
Under-filling and reviewing at two to four weeks is safer than correcting in one session. Tissue that is overfilled stretches, and stretched skin does not shrink back — which is how faces end up looking filled rather than rested.
The face is assessed at rest and in movement, photographs are taken, and the medical history is reviewed — pregnancy, autoimmune disease, cold sores, previous fillers and where they were placed. Previous permanent filler changes the plan entirely.
The areas, the product, the volume and the cost are agreed in writing before anything is opened. The risks are explained, including vascular occlusion, and you are told that hyaluronidase — the enzyme that dissolves the product — is kept in the clinic.
Thirty to sixty minutes including numbing cream. Injections take ten to twenty of those minutes. Lips and tear troughs are the most sensitive; most people describe pressure rather than pain.
Swelling peaks at 24–48 hours, and bruising can take a week to fade. Avoid heat, sauna, intense exercise and alcohol for 24–48 hours, and dental work for two weeks where the lips or nasolabial area were treated. Sleeping slightly elevated helps the first night.
The result is judged once the swelling has gone. A small top-up is sometimes appropriate; a correction is not made in the first week, when everything looks larger than it will be. Further treatment is planned around how long the product actually lasts in your tissue.
These are medical injections into a vascular area. The serious risks are uncommon, but they are the reason this belongs in a clinic with a doctor present and a reversal agent in the fridge.
Hyaluronic acid can be dissolved with hyaluronidase, which is why it is the only filler worth using in the face. Permanent products and unlabelled substances cannot be removed, and they are the commonest reason a patient is turned away or sent for surgery.
Numbing cream is applied for twenty to thirty minutes, and most products contain lidocaine. Lips and the under-eye area are the most sensitive — discomfort rather than pain, and it lasts seconds per injection.
Yes, if it is hyaluronic acid: hyaluronidase dissolves it within a day or two. That is not a reason to overfill, but it is why the product matters more than the price.
Not if it is placed in the right plane and kept conservative. An obvious result usually means too much product, too superficially, in an area that needed support rather than volume.
Every six to eighteen months depending on the product, the area and how quickly you break it down. Lips and areas that move a lot tend to need topping up sooner than deep cheek support.
Send two photographs — front and three-quarter, at rest — and a doctor reviews them. You get an honest answer on whether filler is the right treatment, and what else might be.
General information, not medical advice. Fillers are prescription medical devices and are only appropriate after a consultation with a qualified practitioner; suitability differs from patient to patient.
