Daily Cosmetic Research Analysis
Three studies stand out today: a systematic review suggests Nd:YAG laser as a minimally invasive option for selected skin cancers with favorable cosmetic outcomes; a cross-sectional analysis of top TikTok sunscreen videos reveals low accuracy and promotional bias despite high engagement; and a prospective comparison shows transoral endoscopic thyroidectomy causes transient chin/lower-lip sensory changes yet remains a cosmetically superior, generally safe alternative.

1. Nd: YAG laser in the treatment of non-melanoma and melanoma skin cancers.
Across 12 studies (7,358 lesions), Nd:YAG laser was used predominantly for basal cell carcinoma with encouraging clearance and cosmetic outcomes in low-risk lesions; evidence for SCC and melanoma is limited and mostly in early/thin cases. Lack of margin control and heterogeneous methods constrain broad adoption, but the modality is a promising minimally invasive option for selected patients, particularly in cosmetically sensitive sites or non-surgical candidates.
Impact: This synthesis aggregates multi-decade experience indicating where Nd:YAG laser fits in oncologic dermatology, balancing tumor control with cosmesis and morbidity.
Clinical Implications: Consider Nd:YAG laser for low-risk BCC (and possibly early SCC) in cosmetically sensitive locations or when surgery is contraindicated, with thorough counseling about lack of histologic margin control and the need for careful follow-up. Avoid routine use in melanoma outside research settings.
Key Findings
- Twelve studies from 1985–2023 reported 7,358 histologically confirmed malignancies treated with Nd:YAG laser: 6,846 BCC (93.0%), 185 SCC (2.5%), 323 melanoma (4.4%), and 4 Bowen’s disease.
- Most favorable outcomes were in low-risk BCC with good cosmetic results and reduced morbidity vs surgery; SCC and melanoma treatments were limited to early/thin lesions with experimental status for melanoma.
- Major limitations include lack of margin control, heterogeneous protocols, and variable recurrence data, restricting generalizability and broad adoption.
Methodological Strengths
- Systematic literature search across major databases over nearly four decades
- Large aggregate lesion count enabling subtype-specific insights and safety signals
Limitations
- Heterogeneity of study designs and protocols; limited randomized data
- No histologic margin control with laser; inconsistent and incomplete long-term recurrence reporting
Future Directions: Prospective, standardized protocols with long-term oncologic outcomes (clearance, recurrence) and comparative effectiveness versus surgery or other modalities, including cost-effectiveness and patient-reported cosmetic outcomes.
Surgical excision remains the cornerstone treatment for skin cancer, considered the gold standard in clinical practice. However, alternative methods such as laser therapy are being explored for their potential to achieve tumor control while minimizing tissue damage and improving cosmetic outcomes. This review analyzes the existing literature on the use of Nd: YAG laser in the management of non-melanoma and melanoma skin cancer, with the aim of evaluating clearance and recurrence rates, as well as gaining deeper i
2. Perception, Quality, and Accuracy of Sunscreen Content on TikTok: SkinMedia Cross-Sectional Content Analysis.
Among the 100 most-liked videos, 74% were positive toward sunscreen, only 35% were accurate, 6% were inaccurate, and none cited references; Global Quality Scores were low. Accuracy negatively correlated with likes and views, while quality correlated with accuracy but not engagement, underscoring a disconnect between popularity and reliability.
Impact: Provides timely, quantitative evidence of misinformation dynamics in a high-reach platform, guiding dermatologists and public health stakeholders on targeted digital interventions.
Clinical Implications: Clinicians should proactively disseminate evidence-based sunscreen guidance on social media, advocate for transparent promotional disclosures, and collaborate with platforms to elevate trustworthy content.
Key Findings
- Of top 100 videos, 74% had positive attitudes toward sunscreen; 35% were accurate, 57% opinion-based, 6% inaccurate; 0% cited references.
- Global Quality Scores were low: 40% poor (1), 31% below average (2), only 2% excellent (5).
- Accuracy negatively correlated with likes (r=-0.229; P=.02) and views (r=-0.242; P=.02); quality correlated with accuracy (r=0.270; P=.007) but not engagement; likes and views strongly correlated (r=0.726; P<.001).
Methodological Strengths
- Structured codebook with predefined metrics (GQS, accuracy, themes) and statistical testing
- Focus on highest-engagement content to assess real-world exposure
Limitations
- Cross-sectional snapshot limited to English-language top-liked videos; potential selection and algorithm bias
- No assessment of behavioral outcomes or longitudinal content evolution
Future Directions: Multi-language, longitudinal analyses and interventional trials to test strategies that improve accuracy/visibility of quality content; partnerships for standardized disclosure and evidence citation.
BACKGROUND: TikTok, with more than 2 billion users worldwide, has become an influential venue for health information, including dermatologic advice. However, concerns remain about the accuracy and impact of sunscreen-related content. OBJECTIVE: This study aimed to assess the quality, accuracy, and themes of popular TikTok videos about sunscreen; evaluate associations with creator credentials and promotional content; and identify implications for public health. METHODS: We conducted a cross-sectional con
3. Sensory changes in the chin and lower lip after transoral endoscopic thyroidectomy.
All 37 transoral patients exhibited immediate postoperative chin/lower-lip sensory disturbance that diminished significantly over time (p=0.028), with 5/37 fully recovered by 2 months; no sensory changes occurred in the conventional group. Operative time was longer with the transoral approach, supporting its cosmetic advantage with minimal long-term sensory compromise when performed within the safety zone.
Impact: Provides prospective, controlled safety data on mental nerve-related sensory outcomes for a scarless thyroidectomy technique, informing patient counseling and surgical selection.
Clinical Implications: Use transoral endoscopic thyroidectomy in appropriately selected benign cases with counseling about expected early numbness that generally improves by 2 months; monitor sensory recovery and weigh longer operative time against cosmetic benefits.
Key Findings
- In the transoral group (n=37), all patients had immediate postoperative sensory disturbances in the chin/lower lip that decreased at 1 and 2 months versus 1 week (p=0.028); 5/37 achieved complete recovery by 2 months.
- No sensory changes occurred in the conventional transcutaneous group (n=40) at any time point.
- Operative times were significantly longer in the transoral group; the approach within a defined safety zone preserved long-term mental nerve integrity.
Methodological Strengths
- Prospective observational design with a contemporaneous control group
- Objective quantitative sensory mapping at multiple postoperative time points
Limitations
- Short follow-up (2 months) may miss late sensory sequelae
- Single-setting sample with modest size; nonrandomized allocation
Future Directions: Longer-term, multi-center studies to define recovery timelines, risk factors for persistent dysesthesia, and strategies (e.g., intraoperative nerve monitoring) to mitigate sensory changes.
BACKGROUND: Minimally invasive thyroid surgery offers cosmetic benefits over traditional approaches, but mental nerve injury risk affecting the chin and lower lip persists. Transoral endoscopic thyroidectomy within a defined safety zone is a scarless alternative that may cause transient sensory changes. METHODS: In this prospective observational study, 77 patients with benign thyroid conditions were enrolled; after exclusions, 37 underwent transoral endoscopic thyroidectomy and 40 underwent conventional
