How to Establish the Baseline for Non-Invasive Technological Regenerative Esthetic Medicine in the Face and Neck Region: A Literature Review

(1) Background: Esthetic regenerative medicine is increasingly in demand for facial and neck rejuvenation due to its proven efficacy, safety profile, and minimal downtime. This study aimed to evaluate the role of standardized assessment tools in optimizing the outcomes of non-invasive regenerative esthetic technologies, both during the treatment course and in follow-up. (2) Methods: A literature review of the main articles published in peer-reviewed journals was conducted to identify high-quality studies addressing the use of validated esthetic scales and questionnaires (patient-reported outcomes) for evaluating the effectiveness of non-invasive regenerative treatments for the face and neck using accessible clinical tools such as photographs and 3D facial scanning. (3) Results: Clinician-reported outcomes (CROs) can be collected using standardized and reproducible photographic documentation and facial scans. The esthetic scales and classifications target both specific facial areas (e.g., upper third, perioral, periorbital) and overall skin appearance. Furthermore, advanced software allows overlay facial scan analysis and wrinkle mapping for precise quantification of improvements. In addition to objective CROs, patient-reported outcomes (PROs) offer essential insights into perceived esthetic changes, satisfaction, and emotional well-being, completing a multidimensional evaluation of treatment efficacy. (4) Conclusions: Standardized evaluation protocols based on accessible tools such as clinical photographs, 3D facial scans, and validated PRO questionnaires are essential for guiding effective, personalized regenerative treatments. Their integration into routine practice enhances clinical decision-making and patient satisfaction. While advanced tools like dermal probes may further refine assessments, they require specific expertise and resources and may be less practical for daily clinical use.
