Summary
Q1 2025 cosmetic-related research coalesced around exposure science, evidence-strengthening trials, platform standardization, and precision imaging. Human exposure experiments showed personal care formulations can amplify dermal uptake and predicted serum levels of environmental SVOCs, while a cross-sector nanocarrier framework advanced safety-by-design and reporting coherence. High-rigor trials expanded pediatric options (once-daily roflumilast for atopic dermatitis; biomimetic hydroxyapatite–fluoride toothpastes for enamel caries). Harmonized international breast implant registries demonstrated scalable, real-world analytics for device risk benchmarking. Mechanistic and platform advances included fascia-driven vascularization for scaffold survival and MSOT-based automated 3D mapping to guide tissue-sparing dermatologic surgery. A cross-disciplinary reconstruction of Roman-era lead pollution contextualized modern exposure policy and risk communication.

3. Mobilization of subcutaneous fascia contributes to the vascularization and function of acellular adipose matrix via formation of vascular matrix complex.
In murine models, subcutaneous fascia migrated to acellular adipose matrix implants, delivering fascia-embedded vessels and forming a vascular matrix complex essential for vascularization and implant survival; restricting fascia impaired vascularization and led to implant collapse.
Impact: Reveals fascia as an active driver of vascularization, linking anatomy to biomaterial integration and informing scaffold engineering and surgical handling for durable, aesthetic outcomes.
Clinical Implications: Encourages fascia preservation/recruitment in soft-tissue reconstruction and engineering scaffolds to integrate with fascia to enhance vascularization and survival.
Key Findings
- Fascia migrates to and encases implants, delivering fascia-embedded vessels.
- A dynamic vascular matrix complex forms and remodels with vascularization.
- Limiting/removing fascia markedly impairs vascularization and causes collapse.
4. Pan-European atmospheric lead pollution, enhanced blood lead levels, and cognitive decline from Roman-era mining and smelting.
Integrating Arctic ice-core archives, atmospheric transport modeling, and modern exposure–response epidemiology, the study infers Roman-era emissions elevated European air lead, increased blood-lead levels, and contributed to population-level cognitive decline.
Impact: Links paleoarchives to modern health effects, reframing legacy pollution burdens with a methodological template relevant to current exposure policy and counseling.
Clinical Implications: Reinforces primary prevention and remediation of legacy contaminants and supports vigilant exposure assessment among at-risk populations.
Key Findings
- Ice-core geochemistry indicates elevated atmospheric lead during the Roman era.
- Modeled background lead likely increased population blood-lead levels.
- Applying modern exposure–response suggests links to cognitive decline.
