Abstract

Objectives: To present a clinical protocol for treating abdominal skin laxity induced by rapid weight loss, utilizing collagen biostimulation through a strategic vectoring technique combined with comprehensive body assessment. Introduction: The increasing use of GLP-1 analogs and derivatives for weight loss can significantly impact body composition, particularly in areas prone to skin laxity such as the abdomen. While patients pursue weight reduction as part of the pursuit of the “ideal body,” they often simultaneously seek aesthetic treatments to address the resulting cutaneous laxity. Cutaneous laxity has become a common aesthetic concern, demanding effective and personalized therapeutic strategies. Although technologies are often incorporated into these protocols, collagen stimulation remains the foundation of treatment. Materials / method: Abdominal biostimulation was performed using a vectorized application technique with calcium hydroxylapatite (CaHA) as the primary agent. Patients underwent global aesthetic assessment, including static and dynamic analysis. Biostimulation was indicated every 3–4 kg of weight loss. Technologies were occasionally combined to enhance skin tightening, depending on individual needs. Results: Preliminary cases demonstrated visible improvement in abdominal tone, with better definition and elevation of the umbilical region. The strategic vectoring allowed consistent outcomes with reduced product use. Video documentation provided enhanced visualization of functional improvements in skin response to movement. Conclusion: GLP-1-induced weight loss can result in profound abdominal skin laxity that requires a tailored and strategic therapeutic approach. The vectorized application of collagen biostimulators, coupled with full-body and dynamic assessment, offers a reliable strategy for restoring tissue firmness and optimizing aesthetic outcomes. Evaluation in motion and outside the primary area of complaint should be incorporated into aesthetic protocols for comprehensive treatment planning.
