In suitable patients, dermal fillers may be used to restore lost volume, enhance facial contours, and improve the appearance of certain lines or hollows. They can be used in areas such as the lips, cheeks, and chin. Not every filler is suitable for every area; the product and treatment site are selected after a medical assessment.

Hyaluronic acid fillers generally provide immediate volume and contouring. Depending on how it is used, calcium hydroxylapatite may provide structural support and stimulate collagen production. PLLA works primarily by supporting collagen production, so its effects develop gradually over time. These products differ in their treatment areas, onset of results, and potential risks.

Temporary swelling may occur immediately after treatment, and this initial appearance should not be considered the final result. To achieve a natural look, facial proportions, tissue characteristics, and the amount of filler required are evaluated together. Excessive or inappropriate filler placement may cause unwanted changes in appearance. When necessary, a gradual, staged approach may be preferred.

The duration of results varies depending on the product, treatment area, amount used, and individual factors. Hyaluronic acid fillers and collagen-stimulating injectables do not last for the same length of time. There is no single timeframe that applies to everyone; the expected duration and follow-up plan are discussed based on the specific product used.

In suitable cases, hyaluronic acid fillers can be reduced or dissolved by a physician using an enzyme called hyaluronidase. However, this procedure carries its own risks, and more than one treatment may be needed. Calcium hydroxylapatite and PLLA fillers cannot be dissolved with the same enzyme. It is therefore important to discuss reversibility before choosing a filler.

Temporary swelling, bruising, and tenderness may occur. Infection or nodules are also possible. A rare but serious complication is vascular occlusion, which can lead to tissue damage or vision loss. If you develop unusual or increasing pain, whitening or dusky discoloration of the skin, or any change in vision during or after treatment, contact the treating physician immediately. Seek emergency medical care without delay for any vision changes.
