Dermal filler injections: what to know

Filler may be used for selected areas affected by volume loss, contour changes, or etched lines. A consultation considers your anatomy, skin quality, movement, medical history, previous procedures, and desired degree of change. [Hyaluronic Acid Filler](/materials/hyaluronic-acid-filler/) is one material used in aesthetic practice; different products behave differently and are chosen for a specific tissue and goal.

The injection itself may involve a needle or cannula, with topical or local numbing used when appropriate. Redness, swelling, bruising, tenderness, firmness, and temporary asymmetry can happen. Results and longevity vary with the area, product, metabolism, and technique.

Tell the clinician about allergies, medicines, bleeding problems, immune conditions, dental work, active infection, and earlier filler or reactions. Ask what to pause only if the clinician advises it. Compare [Dermal Fillers](/treatments/injectables/dermal-fillers/) with options such as [Botox](/treatments/injectables/botulinum-toxin-injection/), a [Collagen Biostimulator Injection](/treatments/injectables/biostimulator-injection/), or [Fat Transfer](/treatments/surgical-dermatology/fat-grafting/). Follow written aftercare and keep the review appointment.

Get prompt advice for worsening pain, swelling, redness, warmth, drainage, or skin colour change. Sudden visual symptoms, severe pain, weakness, confusion, or difficulty speaking require emergency care. Do not massage or attempt to correct a new problem yourself unless a medical professional directs you.

Ask what problem is being treated, which product and depth are planned, what alternatives exist, and how an unwanted result or complication would be handled. Ask when you should contact the clinic and what recovery signs are expected.
