Kairax™ Sub-Q with Lidocaine is a professional cross-linked hyaluronic acid (HA) dermal filler developed for deep tissue volumisation and structural contouring. It is positioned within the Kairax range for subcutaneous placement in areas requiring enhanced projection, shape retention, and structural support. In clinical practice, Kairax™ Sub-Q is commonly selected for treatment areas such as the cheeks, jawline, chin, nasolabial folds, and selected contour-focused applications, subject to full patient assessment and anatomical consideration. It is intended for practitioners requiring a higher-support HA gel suitable for deeper planes. Kairax™ Sub-Q is supplied in a 1.0 ml prefilled syringe with sterile needles and is designed for professional use by trained and licensed aesthetic medical practitioners. As with all dermal fillers, product selection, depth, and volume should be determined according to indication, tissue characteristics, and practitioner judgement. How It Works Cross-linked hyaluronic acid is placed into the subcutaneous tissue plane to provide volume support and structural contouring. HA is hydrophilic and binds water within the treated area, contributing to tissue support and projection. The gel is manufactured using a proprietary cross-linking approach intended to support cohesivity and viscoelastic behaviour appropriate for deeper placement.
