Summary
February’s cosmetic research was led by high-quality randomized and real-world evidence and by platform innovations. A Phase 3 pediatric RCT of once-daily roflumilast 0.05% expanded steroid-sparing options for toddlers with atopic dermatitis, while a triple-blind trial favored biomimetic hydroxyapatite–fluoride toothpastes for pediatric enamel caries. Harmonized international breast implant registries delivered robust, clinically actionable revision risk estimates. On the technology front, a flexible microLED skin patch showed early clinical rejuvenation benefits, and a cross-sector nanocarrier definition framework advanced safety-by-design and regulatory alignment.

1. Efficacy and Safety of Once-Daily Roflumilast Cream 0.05% in Pediatric Patients Aged 2-5 Years With Mild-to-Moderate Atopic Dermatitis (INTEGUMENT-PED): A Phase 3 Randomized Controlled Trial.
A double-blind Phase 3 RCT (n=652) showed once-daily roflumilast 0.05% for 4 weeks significantly improved vIGA-AD success (25.4% vs 10.7%), EASI-75 (39.4% vs 20.6%), and itch (WI‑NRS success 35.3% vs 18.0%) in children aged 2–5 years, with pruritus reduction within 24 hours and low, mostly mild/moderate adverse events.
Impact: High-quality, preregistered Phase 3 evidence expands safe, steroid-sparing topical therapy into the 2–5-year age group, a population with limited nonsteroidal alternatives.
Clinical Implications: Consider once-daily roflumilast 0.05% for toddlers with mild-to-moderate AD as a well-tolerated steroid-sparing option; long-term safety and head-to-head trials against topical steroids are still needed.
Key Findings
- Week‑4 vIGA‑AD success: 25.4% (roflumilast) vs 10.7% (vehicle); p<0.0001.
- EASI‑75 at Week 4: 39.4% vs 20.6%; WI‑NRS (itch) success: 35.3% vs 18.0%; itch improved within 24 hours.
- Low treatment‑emergent adverse event rates; stinging/burning causing definite discomfort reported by ≤0.7%.
2. Hydroxyapatite-Fluoride Toothpastes on Caries Activity: A Triple-Blind Randomized Clinical Trial.
A triple-blind randomized clinical trial of 610 preschool children over 24 months found greater inactivation of enamel caries lesions with hydroxyapatite–fluoride formulations compared with monofluorophosphate controls, with significant benefits for enamel lesions and active-to-inactive transitions in primary dentition.
Impact: Large, long-duration pediatric prevention trial provides high-level evidence favoring biomimetic hydroxyapatite–fluoride formulations for enamel caries control.
Clinical Implications: For children with active enamel lesions, consider hydroxyapatite–fluoride toothpastes as an evidence-based option alongside standard oral hygiene and dietary counseling.
Key Findings
- Triple‑blind RCT (n=610; 24 months) comparing HAF toothpastes (1000/1450 ppmF) vs NaMFP controls.
- Significantly greater enamel lesion inactivation and favorable active→inactive transitions in primary dentition in the HAF group.
- High feasibility with a 3×/day brushing protocol; 518 children completed per-protocol.
3. Comparing International Revision Incidence of Commonly Used Breast Implants.
A harmonized pooled cohort analysis of Australian and Dutch breast implant registries (150,969 implants) using frailty Cox models compared complication-related revision incidence. Cosmetic anatomical polyurethane–silicone implants had lower revision hazard versus anatomical textured–silicone (HR 0.38), though 5‑year cumulative differences across types were small.
Impact: Demonstrates the feasibility and clinical value of international registry harmonization to deliver robust, actionable real-world safety estimates for implant selection and surveillance.
Clinical Implications: Use pooled registry estimates to inform shared decision-making on implant type; continued registry participation and inclusion of surgical variables will refine long-term risk profiles.
Key Findings
- Harmonized pooling enabled analysis of 150,969 implants with time-to-event modeling.
- Revision incidence: 6.3% (reconstructive) vs 1.2% (cosmetic).
- Cosmetic anatomical polyurethane–silicone implants had lower revision hazard vs anatomical textured–silicone (HR 0.38; 95% CI 0.22–0.64), but 5-year cumulative differences were minimal.
4. Flexible, surface-lighting MicroLED skin patch for multiple human skincare.
Engineering and early clinical testing of a flexible surface‑lighting microLED patch demonstrated uniform, high‑density irradiation conforming to skin, with initial clinical benefits in pore tightening and rejuvenation.
Impact: Clinically tested wearable phototherapy platform that addresses flexibility and uniformity limitations of conventional LEDs, with immediate translational relevance.
Clinical Implications: May broaden effective, tolerable at‑home phototherapy for cosmetic indications; requires randomized trials, dose optimization, and long-term safety data for widespread adoption.
Key Findings
- Developed FSLED patch enabling skin conformity and uniform emission via pick-and-place transfer.
- Supports high-density irradiation over large areas with mechanical flexibility.
- Early clinical testing showed improvements in pore tightening and rejuvenation.
5. A systematic review of nanocarriers used in medicine and beyond - definition and categorization framework.
A cross‑sector systematic review proposes a size (1–1000 nm) and function‑based definition and categorization by material origin/composition to standardize risk assessment and reporting for topical and injectable products.
Impact: Establishes a unifying, actionable framework that enables safety‑by‑design, consistent characterization, and prioritized evaluation of high‑risk nanocarriers across cosmetics and therapeutics.
Clinical Implications: Guides developers on selection, documentation, and preclinical safety assessment of nanocarriers for topical/injectable products, facilitating regulatory submissions and standardized reporting.
Key Findings
- Proposes nanocarrier definition based on size (1–1000 nm) and function for risk assessment alignment.
- Categorizes by origin and chemical composition to prioritize evaluation.
- Highlights cross‑sector use (medicine, cosmetics, agriculture, consumer products) and environmental considerations.
