Diamond Technique: A Triple Treatment for Neck and Décolletage Rejuvenation.

Background: In the pursuit of integral beauty and a harmonious overall appearance, individuals are increasingly seeking cosmetic treatments for both facial and extrafacial regions. Among these areas, the neck and décolleté have become focal points for care due to their visibility and susceptibility to postsurgical scarring and dyschromia compared with the face. Environmental stressors and sun exposure contribute to aging signs in these areas, prompting a demand for effective, minimally invasive procedures with reduced downtime and minimal risks. Biostimulators, hyaluronic acid, laser therapy, microfocused ultrasound and neurotoxins have become key players in addressing these concerns.

Aims: This manuscript introduces the Diamond technique, which uses a diamond-shaped acetate device to perform a minimally invasive protocol combining calcium hydroxyapatite, hyaluronic acid, and incobotulinumtoxinA for neck and décolleté rejuvenation.

Patients/methods: The technique involves two steps: solution preparation and device-guided injections. The diamond-shaped device was developed to guide the injections, enhancing precision and reproducibility and facilitating medical training. The device's strategic markings aid in solution application, ensuring a multidimensional approach to rejuvenation. Four female patients, aged between 55 and 63 years were used to demonstrate the technique, with two categorized as grade II and two as grade III according to the Merz scale of neck laxity at rest.

Results: The four examples demonstrate improvements in skin laxity, wrinkles, and overall skin quality. Two participants reported "good results," and two reported results "beyond expectations." The Diamond technique's potential lies in its ability to provide predictable outcomes, individualized treatments, and patient satisfaction.

Conclusion: While the authors assert the technique's safety and efficacy, the need for controlled studies is crucial. Rigorous, long-term studies are warranted to validate its effectiveness and safety compared with the existing approaches.
