Hyaluronic Acid Fillers

Hyaluronic acid (HA) filler treatments at Infinity Clinic are performed by MUDr. Petra Meluzinová, Ph.D., a surgical specialist with expertise in facial anatomy. HA fillers restore volume, define contour, and lift soft tissue in areas affected by age-related fat redistribution and collagen loss. Applications include lip augmentation and modelling, nasolabial fold softening, cheek and mid-face volumisation, chin and jawline definition, and tear trough correction. Hyaluronic acid is a naturally occurring molecule in the body, making it biocompatible and reversible with hyaluronidase enzyme if adjustment is needed. Results are immediate and typically last 6–18 months depending on product viscosity, injection depth, and anatomical location.

Hyaluronic acid (HA) filler treatment at Infinity Clinic (listed under aplikace kyseliny hyaluronové and lip modelling — modelace rtů) is led by MUDr. Petra Meluzinová, Ph.D., whose surgical credentials include a PhD in Surgery and membership of FESSH, bringing a deep understanding of facial tissue planes that is essential for safe, natural-looking filler placement. **What hyaluronic acid fillers do:** HA is a polysaccharide chain that binds water molecules, creating a hydrophilic gel. When injected into the dermis or subcutaneous tissue, it fills space, adds volume, and stimulates fibroblast activity — contributing to both immediate volumisation and longer-term collagen remodelling. The crosslinking degree of the HA determines its viscosity and cohesivity, which dictates where in the face it is appropriately placed. **Treatment areas at Infinity Clinic:** - **Lip augmentation and modelling (modelace rtů):** Increasing lip volume, defining the vermillion border, correcting asymmetry, enhancing Cupid's bow definition - **Nasolabial folds:** Softening the lines from nose to mouth corner - **Cheeks and mid-face:** Restoring lost volume in the malar area for a lifted, more youthful midface - **Tear trough / periocular:** Reducing the hollow under-eye appearance (requires high injection skill — periocular vascular anatomy demands precise technique) - **Chin and jawline:** Projecting or squaring the chin, softening jowl shadow - **Neck and décolletage rejuvenation:** HA and biorevitalization products for superficial skin hydration - **Hand rejuvenation:** Restoring dorsal hand volume **Products and reversibility:** Modern crosslinked HA fillers (Juvederm, Restylane, Belotero product families) are the standard of care. Crucially, all HA fillers are reversible with hyaluronidase injection in the rare event of overcorrection, vascular compromise, or patient dissatisfaction. **Session experience:** A topical anaesthetic cream is applied 30–45 minutes before the procedure, significantly reducing injection discomfort. Lidocaine-containing filler formulations further ease discomfort during injection. Mild swelling and potential bruising at injection sites are normal and resolve in 24–72 hours for most areas. Lip swelling can persist 5–7 days. **Contraindications:** Active skin infection near the injection site, autoimmune skin conditions, allergy to HA or lidocaine, pregnancy, and breastfeeding.
