Dermal Fillers

Injectable hyaluronic acid dermal fillers restore facial volume, smooth deep static lines, and shape the lips and perioral area at EsteticUsti. Unlike botulinum toxin, which relaxes muscles, fillers physically fill the space beneath the skin — lifting nasolabial folds, replacing the fat pads lost to ageing under the eyes, and adding definition and volume to the lips. The clinic offers filler dissolving (hyaluronidase enzyme) for corrections if needed. Results are immediate and last approximately 18 months, varying by area and product viscosity.

Hyaluronic acid (HA) is a naturally occurring polysaccharide present throughout the body's connective tissue, synovial fluid, and skin dermis, where it binds water molecules to maintain tissue hydration and structural integrity. Age-related loss of HA — combined with bone resorption, muscle atrophy, and fat compartment shifting — produces the hollowing, sagging, and shadowing that characterise facial ageing. Injectable HA dermal fillers replace this lost volume through a precise, reversible injection technique. At EsteticUsti, dermal fillers are administered for several distinct indications. Under-eye (tear trough) correction addresses the hollowed appearance and dark circles caused by septal descent and volume loss in the infraorbital fat pad — one of the most technique-sensitive filler applications, requiring understanding of the orbital anatomy to avoid complications. Nasolabial fold correction fills the deep groove between the cheek and upper lip. Perioral area treatment smooths fine lines radiating from the lip border (smoker's lines). Lip enhancement adds volume and definition to the vermillion border and the body of the upper or lower lip. Filler products are graded by their HA cross-linking density, with denser gels selected for deeper structural support (nasolabial folds, chin, cheekbones) and lighter gels for superficial fine lines and tear troughs. The treating physician selects the appropriate product and viscosity at consultation. The procedure involves topical anaesthetic for comfort; HA fillers also contain lidocaine for in-situ numbing during injection. Results are visible immediately and develop further over 2–4 weeks as the filler integrates with surrounding tissue. HA fillers are fully reversible: hyaluronidase enzyme can dissolve the product in 24–48 hours if correction is needed. Contraindications include active skin infections, herpes labialis, and blood-thinning medications.
