1. The global regulatory landscape of stem cell medical aesthetics: challenges, comparisons, and pathways to coordination.
This comparative policy analysis maps major jurisdictions’ regulation of stem cell-based aesthetics, highlighting gaps in definitions, risk stratification, and oversight for derivatives like exosomes. It proposes harmonized core definitions, a risk-based tiered classification distinguishing medical vs cosmetic uses, and a hybrid model of conditional approval with real-world evidence tracking.
Impact: By offering a concrete pathway for international coordination, this work can directly inform policymakers and professional societies, improving safety and curbing misleading marketing of stem cell-derived cosmetic products.
Clinical Implications: Clinicians should scrutinize the regulatory status of stem cell-derived products (e.g., exosomes), distinguish cosmetic from medical claims, and emphasize evidence-based consent while advocating for post-market data collection.
Key Findings
- Identifies major cross-country discrepancies in definitions, risk perception, and regulatory philosophy for stem cell-based aesthetics.
- Calls for unified core definitions and risk-based tiered classification, especially for derivatives such as exosomes.
- Advocates a hybrid model combining conditional approval with real-world evidence tracking to balance innovation and safety.
- Emphasizes strengthening fundamental research and standardized efficacy assessments, including instruments and PROs.
Methodological Strengths
- Comprehensive cross-jurisdictional comparative analysis spanning the US, EU, Japan, South Korea, and China.
- Actionable policy framework linking taxonomy, risk stratification, and evidence generation.
Limitations
- Narrative policy analysis without formal PRISMA-method systematic review methods.
- Lack of empirical outcome data; rapidly evolving regulations may limit durability of conclusions.
Future Directions: Develop consensus definitions for cell-derived cosmetic products and pilot risk-tiered, conditional approval pathways with mandated real-world registries and standardized efficacy endpoints.
This paper systematically examines the regulatory frameworks of major regulatory bodies-including the United States, the European Union, Japan, South Korea, and China-regarding the use of stem cells and their derivatives (such as conditioned media and exosomes) for cosmetic purposes. Despite the rapid global growth of "stem cell medical aesthetics" within the cosmetic medical market, its scientific evidence remains insufficient, and it faces the core challenge of inconsistent regulatory systems. Through in-depth comparative analysis, this paper not only reveals profound differences among nations in risk perception, regulatory philosophy, and terminology definitions, but also dissects the resulting market fragmentation and patient safety risks. Based on this, the paper proposes feasible pathways to advance international regulatory coordination: The primary task is to unify core definitions and classification standards (especially for derivatives like exosomes) based on scientific consensus, and establish a risk-based tiered regulatory mechanism that clearly distinguishes medical from cosmetic applications. Concurrently, fundamental research should be strengthened and specific efficacy assessment standards (e.g., instrument measurements and patient-reported outcomes) should be developed.
2. Cosmetic after-feel modulates brain activity in sensory and reward networks: an fMRI study.
In a within-subject fMRI study of 20 women, a cosmetic formulation differing only by emulsifier (cream A) engaged orbitofrontal, amygdalar, and striatal regions beyond primary somatosensory cortex during after-feel self-touch. Reward-related responses showed right-hemispheric dominance, suggesting that specific ingredients can enhance affective tactile salience, potentially via C-tactile pathways.
Impact: This work introduces a neurobiological framework for designing emotionally engaging cosmetic textures, linking ingredient-level formulation to central reward processing.
Clinical Implications: While not immediately practice-changing, the findings inform patient experience optimization and could guide product selection for individuals seeking mood-enhancing sensorial profiles.
Key Findings
- Cream A (emulsifier-different) elicited broader activation including orbitofrontal cortex, amygdala, putamen, beyond primary somatosensory areas.
- Reward-related activations (striatal/insular) showed right-hemispheric dominance contralateral to stimulated hand.
- No-cream and cream B primarily engaged primary somatosensory regions consistent with basic tactile encoding.
- Findings support a hierarchical integration from sensory encoding to affective appraisal, implicating C-tactile pathways.
Methodological Strengths
- Within-subject design with standardized self-touch speed and preprocessing pipeline.
- Use of GLM-based fMRI analysis targeting sensory and reward networks.
Limitations
- Small sample of healthy women only; proof-of-concept limits generalizability.
- Single-session design without behavioral hedonic ratings linked to neural signals.
Future Directions: Include larger, sex-balanced samples, blinded sensory ratings, and ingredient-controlled factorial designs to map formulation features to neural signatures and behavior.
The affective dimensions of cosmetic textures were investigated using functional magnetic resonance imaging (fMRI) to examine how after-feel, defined as residual tactile sensations persisting on the skin after product application, modulates sensory and emotional processing. Twenty healthy women took part in three conditions: no cream (control), cream A, or cream B, differing only in emulsifier composition. A fixed amount of cream was applied to predefined areas of the left hand. After absorption, participants stroked these areas at a controlled speed. fMRI data were acquired during this self-touch task, preprocessed using a standardized pipeline, and analyzed using a general linear model. Results showed that the no-cream and cream B conditions primarily engaged primary somatosensory regions, consistent with basic tactile encoding. In contrast, cream A additionally recruited brain areas involved in affective and reward processing, including the orbitofrontal cortex, amygdala, and putamen, with key reward-related responses, notably within striatal and insular regions, showing a right-hemispheric dominance contralateral to the hand receiving the tactile input.
3. Analysis of US Food and Drug Administration Data on Radiofrequency Microneedling Device Complications.
Postmarketing MAUDE analysis of 114 RFMN reports (224 events) highlights textural change (25%), dyspigmentation (18.3%), and fat loss (11.6%) as leading complications, with additional inflammatory reactions, burns, and pain. Findings underscore operator training, patient counseling, and standardized surveillance to mitigate risks.
Impact: As energy-based devices proliferate, real-world safety signals guide risk mitigation, informed consent, and training priorities in aesthetic dermatology.
Clinical Implications: Discuss risks of textural change, dyspigmentation, and potential fat atrophy during consent; tailor device settings and anatomic site selection; ensure operator training and encourage post-procedure monitoring and adverse event reporting.
Key Findings
- 114 MAUDE reports encompassing 224 adverse events related to RFMN were identified (2013–2025).
- Most frequent complications: textural changes (25.0%), pigmentary alteration (18.3%), fat loss (11.6%).
- Other notable events included inflammatory reactions (8.0%), burns (6.3%), and pain (5.4%).
- Face, neck, and abdomen were the most commonly treated regions.
Methodological Strengths
- National postmarketing database capturing device-related adverse events over a 12-year span.
- Systematic categorization of narrative reports into clinically meaningful outcomes.
Limitations
- Underreporting and reporting bias inherent to voluntary MAUDE submissions; lack of denominators prevents incidence estimation.
- Heterogeneity and incomplete narratives limit causality assessment and risk factor analysis.
Future Directions: Establish prospective registries with standardized data elements (device parameters, skin type, anatomic site) and link to outcomes to quantify risk and inform best practices.
BACKGROUND: Radiofrequency microneedling (RFMN) is increasingly used for rejuvenation, acne scars, and tightening. Although marketed as minimally invasive, lasting adverse effects have been reported. Postmarketing surveillance provides insight into real-world safety. OBJECTIVE: To characterize adverse events associated with RFMN devices reported to the US FDA MAUDE database, emphasizing the frequency and spectrum of complications. MATERIALS AND METHODS: A retrospective review of FDA MAUDE reports from January 2013 to October 2025 was conducted. Entries involving RFMN were analyzed for treatment location and adverse outcomes. Narrative descriptions were categorized into clinically relevant events, and descriptive statistics summarized complication frequencies and anatomic sites. RESULTS: A total of 114 reports with 224 events were identified. The most frequent complications included textural changes (n = 56, 25.0%), pigmentary alteration (n = 41, 18.3%), and fat loss (n = 26, 11.6%). Inflammatory reactions (n = 18, 8.0%), burns (n = 14, 6.3%), and pain (n = 12, 5.4%) were also frequently reported. The face, neck, and abdomen were the most treated anatomic regions. CONCLUSION: Although RFMN is generally safe, significant complications may occur. Experience and proper training are crucial to minimizing risks. Clinicians should counsel patients, monitor outcomes, and support surveillance and standardized reporting to improve safety.
