Dermal Fillers (Hyaluronic Acid and CaHA)

Dermal filler treatments at Berska Clinic are performed by MUDr. Šárka Běrská using hyaluronic acid (HA) and calcium hydroxyapatite (CaHA) injectables. HA fillers restore volume, hydrate, and smooth lines through their natural affinity for water; CaHA provides immediate structural lift plus longer-term collagen and elastin stimulation. Applications include lip augmentation (the most frequently requested procedure at the clinic), under-eye hollows, nasolabial folds, marionette lines, cheek volume restoration, chin and nose contouring, and full-face liquid lifting. Injections are delivered by thin needle or cannula depending on the zone.

Dermal fillers are injectable materials placed precisely within the skin or subcutaneous tissue to restore volume, define contours, smooth folds, and enhance specific anatomical features. At Berska Clinic, two primary categories of filler are used, each with distinct properties and applications. Hyaluronic acid fillers are cross-linked chains of hyaluronic acid — a polysaccharide naturally present in human connective tissue and skin. Different formulations have varying cross-linking densities, which determines their rheological properties: thin, low-viscosity HA gels are used for superficial fine lines and lip borders; denser, high-G-prime formulations provide structural lift in the cheeks or chin. All HA fillers are biodegradable and reversible — if the result is unsatisfactory or if complications arise, hyaluronidase enzyme can dissolve the product. Effect duration for HA ranges from 6 to 18 months depending on the product, treatment zone, and individual metabolism. Calcium hydroxyapatite (CaHA), marketed under brands such as Radiesse, consists of microspheres of CaHA suspended in an aqueous gel carrier. Upon injection, the carrier provides immediate volume and lift. Over the following weeks to months, the microspheres stimulate fibroblasts to produce type I and type III collagen and elastin — the structural proteins responsible for skin firmness. The product itself is gradually resorbed over 12–18 months, leaving behind newly deposited collagen. MUDr. Běrská describes this as a triple effect: immediate volume, collagen stimulation, and elastin stimulation. The most frequently performed procedure at Berska Clinic is lip augmentation. MUDr. Šárka Běrská has extensive experience with lip anatomy and the nuanced techniques required to achieve natural-looking enhancement — careful attention to lip proportion, border definition, and overall facial harmony distinguishes experienced medical practitioners from those less familiar with facial anatomy. Other commonly treated areas include: nasolabial folds, marionette lines, chin modeling (lengthening, projecting, or reshaping), non-surgical nose correction (rhinoplasty), tear trough/under-eye dark circles, cheek volume restoration, jawline definition, and ear lobe rejuvenation. Full-face liquid lifting combines multiple small-volume deposits to produce a comprehensive volumisation and lifting effect. Injection technique: thin needles are used for superficial and precise placement; cannulas are preferred for larger-volume deposits in mobile areas (cheeks, nasolabial folds) as they reduce bruising risk by navigating around blood vessels rather than piercing them. Aftercare: mild bruising and swelling are normal in the first 24–72 hours. Avoid heavy exercise, heat (sauna, sun), and alcohol for 24 hours. Gentle massage may be advised for certain areas.
