1. Diet and Everyday Product Use and Serum Per- and Polyfluoroalkyl Substances Levels in the Korean Population: Findings from the Korean National Environmental Health Survey.
In a nationally representative Korean sample (n=3,768), sparse reduced-rank regression identified two dominant exposure patterns: seafood and food contact materials driving overall PFAS levels, and a PFHxS-specific pattern characterized by processed foods and non-dietary sources (e.g., fast food, disposable paper cups, hot-food plastic containers, body wash, household cleaners). Sex-stratified analyses implicated cosmetics as a major PFHxS source in women.
Impact: This large, representative analysis clarifies real-world PFAS exposure sources, highlighting cosmetics as a meaningful PFHxS contributor in women and informing risk communication and regulatory priorities.
Clinical Implications: Clinicians and public health practitioners can counsel patients—especially women—on reducing PFAS exposure by moderating seafood intake, scrutinizing food contact materials, and selecting PFAS-safe cosmetics and personal care products.
Key Findings
- Two dominant exposure patterns were identified: overall PFAS driven by seafood and food contact materials, and a PFHxS-specific pattern linked to processed foods and non-dietary sources.
- Cosmetics emerged as a major PFHxS exposure source in women; body wash was a notable source in men.
- Age-stratified patterns differed, with older adults more influenced by seafood and younger adults by food contact materials; students resembled adults ≥40 years.
Methodological Strengths
- Nationally representative sample with objectively measured serum PFAS
- Advanced multivariate modeling (sparse reduced-rank regression) and stratified analyses
Limitations
- Cross-sectional design limits causal inference
- Questionnaire-based exposure assessment may introduce recall and residual confounding
Future Directions: Longitudinal cohorts linking product-level PFAS measurements to serum changes, intervention studies testing exposure reduction strategies, and regulatory evaluations of PFAS in cosmetics.
Per- and polyfluoroalkyl substances (PFASs) are persistent synthetic chemicals widely used in consumer and industrial products and lead to ubiquitous human exposure and adverse health effects. However, how various exposure sources contribute relatively to the human PFAS burden remains unclear. The primary exposure sources contributing to serum PFAS concentrations, specifically dietary intake and everyday product use, were examined in a nationally representative sample using Korean National Environmental Health Survey Cycle 4 (2018-2020) data, including 2,990 adults and 778 secondary school students. Information on exposure sources was collected through questionnaires, and serum concentrations of perfluorohexanesulfonic (PFHxS), perfluorooctanesulfonic, perfluorooctanoic, perfluorononanoic, and perfluorodecanoic acids were measured.
2. Efficacy of Microneedle Fractional Radiofrequency Combined With Platelet-Rich Plasma for the Treatment of Melasma: A Split-Face, Randomized Trial.
Both MFR-treated sides showed significant mMASI reductions at 3 months. Adding PRP did not further improve global clinical pigment scores or ultrasound-detected structural changes, though VISIA metrics (red area, brown spots) improved significantly on the combination side only. Safety was acceptable with minimal adverse events.
Impact: This evaluator-blinded randomized split-face trial provides practical, comparative evidence that PRP may not add clinically meaningful global benefit to MFR for melasma, guiding cost-effective therapy choices.
Clinical Implications: MFR is a reasonable option for Fitzpatrick III–IV melasma. Routine PRP addition may be unnecessary for global outcomes, though it may assist erythema- and pigment-related imaging features; shared decision-making should weigh added cost, downtime, and patient priorities.
Key Findings
- Both sides (MFR±PRP) achieved significant reductions in mMASI/hemi-mMASI at 3 months.
- Adjunctive PRP did not improve global clinical pigment scores or ultrasound-measured structural changes versus MFR alone.
- VISIA showed significant reductions in red area and brown spot scores on the combination side only; safety profile was favorable.
Methodological Strengths
- Randomized, evaluator-blinded split-face design minimizing inter-individual variability
- Use of objective imaging (VISIA) and ultrasound in addition to clinical scores
Limitations
- Small sample size (n=30; 29 completed) and short follow-up (3 months)
- Limited generalizability to Fitzpatrick III–IV and specific device/PRP protocols
Future Directions: Larger, multi-center RCTs with longer follow-up to assess durability and relapse, optimization of PRP protocols, and subgroup analyses by melasma subtype and skin type.
BACKGROUND: Melasma is a common facial pigmentary disorder that markedly impairs quality of life, yet current treatments often yield incomplete clearance and frequent relapse. Microneedle fractional radiofrequency (MFR) can remodel the dermis and enhance transdermal delivery, whereas platelet-rich plasma (PRP) provides growth factors that may modulate melanogenesis and inflammation. AIMS: To compare the efficacy and safety of MFR combined with PRP versus MFR alone in the treatment of facial melasma. METHODS: In this prospective, randomized, evaluator-blinded, split-face trial, 30 patients with stable, symmetrical facial melasma received two sessions of MFR. One facial side was randomly assigned to receive adjunctive PRP and the contralateral side received saline. Outcomes included modified Melasma Area and Severity Index (mMASI) and hemi-mMASI scores, VISIA skin analysis, patient-reported satisfaction, and adverse events.
3. Dermocosmetics in Acne Vulgaris: South African Consensus Recommendations With a Focus on Skin of Color.
A South African expert panel synthesized clinical experience and literature to recommend integrating dermocosmetics into acne care to support the epidermal barrier, reduce treatment-related irritation, address pathogenic pathways, and manage post-inflammatory hyperpigmentation in skin of color. Practical guidance covers adjunctive use with prescription therapy, monotherapy in mild disease, and maintenance regimens.
Impact: Delivers regionally contextualized, skin-of-color–focused guidance to optimize acne outcomes with dermocosmetics, potentially improving adherence and reducing sequelae like hyperpigmentation.
Clinical Implications: Incorporate dermocosmetics to enhance tolerability and target acne pathways; prioritize barrier-repair formulations and pigment-modulating agents in skin of color; use as adjuncts, mild-case monotherapy, and maintenance therapy.
Key Findings
- Dermocosmetics support barrier repair, reduce irritation from conventional acne treatments, and target pathogenic pathways.
- Guidance emphasizes management of acne-induced hyperpigmentation in skin of color.
- Recommendations span adjunctive therapy, monotherapy in mild acne, and maintenance to sustain remission.
Methodological Strengths
- Structured expert meetings integrating regional clinical experience
- Targeted review of international and local evidence to inform recommendations
Limitations
- Consensus-based methodology without PRISMA-level systematic review
- Lack of quantitative synthesis or graded evidence for specific products
Future Directions: Head-to-head RCTs of dermocosmetic regimens in diverse skin types, pigment-centric outcomes, cost-effectiveness, and real-world implementation studies.
BACKGROUND: Acne vulgaris is one of the most common dermatological disorders worldwide, affecting both adolescents and adults. It frequently leads to significant psychosocial and physical sequelae, including acne-induced hyperpigmentation and scarring. Beyond pharmaceutical therapies, dermocosmetics-topical formulations enriched with active ingredients in cosmetically elegant vehicles-have emerged as essential partners in acne management. They optimize clinical outcomes by supporting skin barrier repair, reducing irritation associated with conventional treatments, and targeting key pathogenic pathways in acne. However, no region-specific guidance exists to inform the effective use of dermocosmetics in South African patients, particularly those with skin of color. AIMS: To develop expert consensus recommendations for the use of dermocosmetics in acne vulgaris management within the South African context. METHODS: This consensus was developed through structured expert meetings and a targeted literature review of current international and local evidence.
