Dermal Fillers

Dermal fillers restore volume loss, enhance facial contours and add fullness to areas like the lips, jawline, cheekbones and temples. Most modern fillers are based on hyaluronic acid (HA) — a naturally occurring molecule in the body, biocompatible and reversible.

What Are Dermal Fillers?

Dermal fillers are sterile, injectable gels made primarily of cross-linked hyaluronic acid in varying densities. They are placed in the skin or subcutaneous layers to restore volume, smooth wrinkles and shape facial contours. Hyaluronic acid is a glycosaminoglycan naturally present in skin, joints and eyes; its capacity to bind water makes it a powerful volumiser and hydrator.

One of HA's most important advantages is its reversibility: if needed, the enzyme hyaluronidase can dissolve the filler quickly and safely. This is a significant safety net not offered by permanent or semi-permanent fillers.

Common Treatment Areas

Each anatomical region calls for filler with a specific density and viscosity. Temples show volume loss early in the ageing process and can be restored with a volumising filler. Under-eye (tear trough) hollows require a fine, low-water-binding product to avoid puffiness. Cheekbones benefit from dense lifting fillers that restore mid-face volume and indirectly support the nasolabial fold.

Lip fillers address volume, definition and hydration; the goal is natural proportion rather than excessive volume. Chin and jawline fillers sharpen profile contours, support facial structure and improve the chin–neck angle. Nasal fillers (non-surgical rhinoplasty) can smooth bumps, lift the tip and add symmetry within carefully selected anatomical limits.

How Are Fillers Different from Botox?

Botox relaxes muscles to soften dynamic lines; fillers restore volume to address structural ageing. Botox is preferred for forehead lines, frown lines and crow's feet. Fillers are chosen for hollow temples and cheeks, deep nasolabial folds, marionette lines and lip volume loss. In many cases, the two are combined for a complete result.

The Procedure

The session begins with a full facial analysis. Areas of volume loss, asymmetries and patient priorities are mapped. Topical anaesthetic cream is applied; most modern fillers also contain lidocaine for comfort. Injection is performed with fine needles or blunt cannulas depending on the area; the total procedure typically takes 20–40 minutes.

Immediate results are visible. Mild swelling, redness or bruising may occur for 1–7 days. Final shaping settles over 2 weeks as the gel integrates with surrounding tissue and water binding stabilises.

Duration

Effects last 6–18 months depending on the area, product type and individual metabolism. Lips and tear-trough zones (high movement, thin skin) generally last shorter; cheekbones and jaw (denser fillers, less movement) last longer. With each maintenance session over time, the natural collagen response improves and intervals can be lengthened.

Safety Profile and Contraindications

Performed by an experienced physician in a clinical setting, HA fillers have a high safety profile. Temporary side effects (swelling, bruising, tenderness) are common and self-resolving. Rare but serious risks include vascular occlusion — which is why physician experience and a thorough anatomical knowledge are non-negotiable. Contraindications include active infection at the injection site, allergy to filler components, pregnancy and breastfeeding.
