HArmonyCa™ hybrid filler to restore connective tissue: An Italian real-life retrospective study.

Background: Facial aging and dermal conditions may negatively influence the quality of life, leading patients to seek aesthetic procedures to restore a more satisfying appearance. HArmonyCa™ is a recently developed hybrid filler that combines the actions of the most common dermal fillers, hyaluronic acid (HA) and calcium hydroxylapatite (CaHA).

Aims: This study investigates the efficacy and safety of HArmonyCa™ in patients affected by chrono- and photoaging and several facial skin conditions.

Patients/methods: One hundred and twenty-nine patients, affected by chrono- and photoaging, and skin conditions such as oily and acne-prone skin, rosacea, or scarring, were treated with HArmonyCa™. Injections followed the retrograde linear fanning technique. A physicians' consensus identified five optimal entry points. The physician and patients assessed treatment outcomes using the Global Aesthetic Improvement Scale (GAIS) 9 months after treatment (including immediate lift effect, skin firmness, and elasticity), and 3D images were taken for documentation. Adverse events (AEs) were evaluated immediately after the procedure and after 9 months.

Results: According to the physician's assessments, all patients displayed an improvement in facial appearance, particularly during movement, with the patients' evaluation showing agreement. Only minor AEs were reporte, which resolved spontaneously. Moreover, HArmonyCa™ treatment proved compatible with different medications and aesthetic procedures.

Conclusions: This study shows that one treatment with HArmonyCa™ yields highly satisfactory outcomes in patients affected by skin conditions. For the first time, we show that HArmonyCa™ is a dynamic filler that improves facial laxity during movement. The treatment proved to be safe and fully compatible with other cosmetic procedures and medications.
