Daily Cosmetic Research Analysis
Across cosmetic and aesthetic dermatology, three studies stand out: a scoping review maps the broad applications and combination strategies of radiofrequency microneedling (RFM) for facial rejuvenation; a 1-year cohort suggests pimecrolimus 1% cream can partially reverse topical corticosteroid-induced facial skin damage; and a comparative cohort shows PRP plus hyaluronic acid mesotherapy improves chloasma more than single-modality treatment with good short-term safety.

1. A Scoping Review of Radiofrequency Microneedling: Clinical Application and Outcome Assessment.
This scoping review maps where and how RFM is used for facial rejuvenation and summarizes outcome assessments. It highlights the enhanced effects of combining RFM with agents such as poly-L-lactic acid, polynucleotides, PRP, or TCA and emphasizes using both patient-reported and objective measures to guide personalized protocols.
Impact: Provides a field-wide synthesis that can standardize assessment and inform combination strategies for RFM in aesthetic practice.
Clinical Implications: Clinicians can consider RFM across multiple facial regions and leverage combinations (e.g., PLLA, polynucleotides, PRP, TCA) to augment collagen remodeling, while adopting standardized subjective and objective outcome measures.
Key Findings
- RFM is applied to cheeks, periorbital areas, mandible, lower face, neck, and photoaged skin.
- Combining RFM with poly-L-lactic acid, polynucleotides, platelet-rich plasma, or trichloroacetic acid can enhance outcomes via collagen synthesis and repair.
- Outcome assessments span subjective patient satisfaction and objective clinical evaluations, enabling personalized treatment strategies.
Methodological Strengths
- Broad database search (PubMed, Web of Science, Embase) with anatomical region–specific synthesis
- Integrates combination-therapy evidence and categorizes subjective/objective outcomes
Limitations
- Scoping review design without quantitative meta-analysis limits effect size estimation
- Heterogeneity in protocols and outcome measures across included studies
Future Directions: Prospective RCTs with standardized RFM parameters and harmonized outcome scales; mechanistic studies of synergy with PLLA, polynucleotides, PRP, and acids.
2. Corticosteroid-induced skin damage improved with pimecrolimus cream 1% treatment: a 1-year study in adults with mild to moderate atopic dermatitis.
In a 48–52-week cohort of adults with AD and TCS-induced facial/cubital skin damage, intermittent pimecrolimus 1% cream led to a 30.5% improvement in dermatoscopic scores and reversal of atrophy/telangiectasia in about half of patients.
Impact: Suggests a steroid-sparing option that may reverse established steroid-induced skin damage in sensitive areas, addressing a common cosmetic concern in AD management.
Clinical Implications: Consider intermittent pimecrolimus 1% cream for patients with TCS-induced atrophy/telangiectasia, especially on the face, while monitoring response with standardized imaging and balancing eczema control.
Key Findings
- Dermatophot dermatoscopic score improved by 30.5% from baseline after intermittent pimecrolimus treatment over 48–52 weeks.
- Approximately half of patients showed reversal of TCS-induced skin atrophy and telangiectasia.
- Objective imaging (dermatoscopy; ultrasound in a subset) was used to document changes in skin structure.
Methodological Strengths
- Long follow-up duration (48–52 weeks) in a real-world cohort
- Objective, device-based assessments (dermatoscopy; ultrasound subset)
Limitations
- Single-arm, nonrandomized design without a control group
- Ultrasound data were only available in a small subset (n=11)
Future Directions: Randomized controlled trials comparing pimecrolimus with TCS taper/withdrawal and other calcineurin inhibitors; histologic and biomarker studies to elucidate reversal mechanisms.
3. Clinical Analysis of PRP Combined With Hyaluronic Acid Mesotherapy in the Treatment of Facial Chloasma.
In 57 patients with chloasma, PRP+HA mesotherapy outperformed PRP or HA alone across MASI reduction and pigment-related indices at 4 weeks. Satisfaction was higher in the PRP+HA group than HA alone, and no serious adverse events were reported.
Impact: Provides comparative clinical evidence supporting a combination biostimulatory strategy for a challenging pigmentary condition with favorable short-term safety.
Clinical Implications: PRP+HA mesotherapy can be considered for chloasma to enhance early improvements in MASI and pigmentation metrics; clinicians should counsel on the preliminary 4-week horizon and plan longer-term maintenance.
Key Findings
- At 4 weeks, effective rates exceeded 50% in both PRP and PRP+HA groups.
- PRP+HA showed greater improvement than PRP or HA alone across MASI reduction and pigment degree/area/quantity indices.
- Patient satisfaction was higher in PRP+HA than HA alone; no serious adverse reactions were observed in any group.
Methodological Strengths
- Three-arm comparative design enables benchmarking of combination versus monotherapy
- Multiple quantitative endpoints (MASI, pigment indices) plus satisfaction and safety monitoring
Limitations
- Nonrandomized allocation with small group sizes and short 4-week follow-up
- Single-center design limits generalizability and durability assessment
Future Directions: Conduct randomized, blinded trials with longer follow-up to assess durability and optimal dosing schedules; include objective imaging/colorimetry and stratify by baseline melasma severity and skin phototype.
