Redefining neck rejuvenation: pain assessment and satisfaction with calcium hydroxyapatite and polydioxanone threads
Abstract
Background: Skin aging is influenced by multiple factors, with collagen loss being the most significant due to its progressive physiological decline. Recent trends favor minimally invasive rejuvenation techniques. This study assessed the pain and satisfaction after collagen stimulation treatments using calcium hydroxylapatite (CAHA) and polydioxanone (PDO) threads in the neck region. Methods: Two groups of four participants each were formed: CAHA and PDO. Outcomes were assessed pre- and post-treatment at six months via data collection, photography, and a structured satisfaction questionnaire. The CAHA group comprised four females aged 30–74 years, while the PDO group included three females and one male aged 37–58 years. Results: Both treatments contributed to safe skin improvement in the neck, enhancing participant satisfaction. No major adverse effects were reported, with minimal downtime. Conclusion: CAHA and PDO threads are effective, minimally invasive options for neck rejuvenation, improving flaccidity, texture, and overall appearance.
