Abstract
Acne, a chronic inflammatory condition of the pilo-sebaceous unit, often results in scarring with significant aesthetic and psychological consequences for patients. While various treatments exist, including surgical and non-surgical approaches, a combined method has shown promise in effectively addressing acne scarring. Lipofilling, with its adipose-derived stem cells, has emerged as a promising technique for volume restoration and collagen stimulation but may not be suitable for all patients, especially those who prefer non-surgical treatments. Recently, a novel approach involving simultaneous injection of hyaluronic acid (HA) and calcium hydroxyapatite (CaHa) has been introduced in the literature, showing lifting properties, improving dermal thickness and skin texture, and inducing neocollagenesis. HArmonyCa™ (Allergan Aesthetics, an AbbVie Company) is a hybrid filler combining HA (20 mg/mL) and CaHa 55.7% (microspheres 25–45 µm) with 0.3% lidocaine in a 1.25-ml syringe. It has demonstrated volumizing, lifting, and skin-tightening effects, along with increased fullness, elasticity, and turgor of the skin. It has also shown an increase in viscoelasticity, suggesting new collagen formation, making it suitable for treating conditions like solar elastosis. Compared to lipofilling, HArmonyCa™ offers a non-surgical alternative with comparable outcomes and patient satisfaction. These findings have led us to employ this hybrid filler for the treatment of post-acne scarring. We present a case of a 35-year-old woman with post-acne scarring, treated with HArmonyCa™ combined with Volite™ injections, CO2 laser resurfacing, and chemical peels. Significant improvement in skin texture, reduction of shadowing effect, and restoration of tissue elasticity were observed, resulting in high patient satisfaction. While HArmonyCa™ presents a promising solution for post-acne scarring, further research is needed to comprehensively evaluate its efficacy and suitability. This study contributes to the growing body of literature exploring the potential applications of hybrid fillers, particularly in addressing post-acne scarring.
