1. Pediatric Skin Care Regimens on TikTok.
Systematic analysis of 100 TikTok skin-care videos by creators ≤18 years found high costs, frequent exposure to potential irritants, and low sunscreen use. The top-viewed content contained numerous potentially sensitizing actives, highlighting preventable risks for children.
Impact: Provides data-driven insight into a rapidly growing pediatric skin-care trend with clear safety implications, informing clinicians and caregivers.
Clinical Implications: Counsel families to simplify pediatric skin care, prioritize sunscreen, and avoid multi-step regimens with multiple active ingredients that increase irritation and allergic contact dermatitis risk.
Key Findings
- Analyzed 100 TikTok videos by creators aged 7–18 years; average 1.1 million views per video.
- Regimens averaged 6 products and cost about $168 per routine.
- Only 26.2% of videos included sunscreen.
- Top 25 most-viewed videos averaged 11 (max 21) potentially irritating active ingredients.
- Twenty inactive ingredients overlapped with the Pediatric Baseline Series allergens used in patch testing.
Methodological Strengths
- Systematic content sampling using new, age-matched accounts to minimize algorithmic bias.
- Ingredient risk mapped against an established pediatric patch testing series.
Limitations
- Cross-sectional design; cannot assess real-world use or outcomes.
- Platform-specific and algorithm dynamics may limit generalizability.
Future Directions: Prospective studies linking product use to dermatologic outcomes in children and evaluating educational interventions to reduce harmful practices.
BACKGROUND AND OBJECTIVES: A recent trend in video-based online content features girls as young as 7 years demonstrating multistep skin care regimens, which may be affecting pediatric skin care practices. We aimed to conduct a systematic analysis of TikTok videos featuring skin care regimens with content creators aged 18 years or younger. METHODS: Two investigators each created a new TikTok account, reporting themselves to be 13 years old. The "For You" tab was used to view relevant content until 100 unique videos were compiled. We collected demographics of content creators, number and types of products used, and total cost of regimens. We created a list of products used and their active and inactive ingredients. The Pediatric Baseline Series used in patch testing was used to identify ingredients with elevated risk of inducing allergic contact dermatitis. RESULTS: Content creator ages ranged from 7 to 18 years. Each video reviewed had an average of 1.1 million views. Regimens featured an average of 6 products, costing an average of $168/regimen. Only one-quarter of videos (26.2%) included sunscreen. The top 25 most-viewed videos contained an average of 11 and a maximum of 21 potentially irritating active ingredients. Twenty of the inactive ingredients are included in the Pediatric Baseline Series. CONCLUSIONS: Skin care regimens on TikTok are costly, infrequently include sunscreen, and often involve exposure to ingredients that carry a risk of irritation, allergic contact dermatitis, and sun sensitivity. They offer little to no benefit for the pediatric populations they are targeting.
2. A Randomised Single-Blind Controlled Trial Comparing Efficacy of Intralesional Vitamin D Injection and MMR (Measles, Mumps, Rubella) Vaccine in Treatment of Warts.
In a single-blind RCT (n=36), both intralesional MMR vaccine and intralesional vitamin D significantly reduced wart size, with a possible advantage of MMR for complete response. Both approaches appeared safe across the short treatment window.
Impact: Direct head-to-head randomized comparison of two low-cost, accessible immunotherapies for common warts provides practical guidance for clinicians.
Clinical Implications: Consider intralesional immunotherapy for recalcitrant warts; dosing every 3 weeks up to three sessions is feasible. MMR may be preferred when aiming for complete response, pending confirmation by larger trials.
Key Findings
- Single-blind randomized controlled trial in a tertiary center with 36 patients aged ≥12 years.
- Both intralesional MMR and vitamin D significantly reduced the size of the largest wart over treatment.
- MMR showed a slight advantage in complete response rate based on secondary outcomes.
- Both treatments were reported as safe in the short-term.
Methodological Strengths
- Randomized, single-blind design with predefined primary and secondary endpoints.
- Clinically pragmatic dosing schedule (every 3 weeks, up to three doses).
Limitations
- Small sample size and single-center design limit generalizability.
- Follow-up duration and detailed statistics on recurrence not provided in the abstract.
Future Directions: Larger, multi-center, double-blind RCTs with longer follow-up to compare complete response, durability, and recurrence; cost-effectiveness analyses.
INTRODUCTION: Common warts are benign skin lesions caused by human papillomavirus (HPV) infection. They are often resistant to conventional treatments and may cause cosmetic and psychological distress. Immunotherapy is a promising alternative that stimulates the host immune system to clear the virus and the infected cells. This study compared the efficacy and safety of two immunotherapeutic agents, intralesional measles, mumps, and rubella (MMR) vaccine and intralesional vitamin D, in the treatment of common warts. METHODS: This was a single-blind randomised controlled trial conducted at a tertiary care hospital in Kolkata, India. Patients aged 12 years or older with common warts were randomly assigned to receive either intralesional MMR vaccine or intralesional vitamin D every 3 weeks for a maximum of three doses or until complete resolution, whichever was earlier. The primary outcome was the reduction in the size of the largest wart. Secondary outcomes included patients' and physicians' global assessment, complete response rate, adverse effects, and recurrence rate. RESULTS: A total of 36 patients were enrolled and analysed. Both MMR and vitamin D groups showed a significant reduction in the size of the largest wart throughout the treatment period ( CONCLUSION: Both intralesional MMR vaccine and intralesional vitamin D are effective and safe immunotherapeutic options for the treatment of common warts. MMR vaccine may have a slight advantage over vitamin D in terms of complete response rate; however, further studies with larger sample sizes and longer follow-ups are needed to confirm this finding.
3. Supramolecular Assembly of Dendrobium officinale Polysaccharides-Hyaluronic Acid and Its Moisturizing Properties.
A supramolecular complex of Dendrobium officinale polysaccharide and hyaluronic acid formed sheet-like structures, enhanced moisture absorption, protected cells from drying injury, and improved skin moisture, roughness, and scale indices in very dry conditions.
Impact: Demonstrates a synergistic, biopolymer-based supramolecular strategy that improves moisturizing performance from bench to real-world dry environments.
Clinical Implications: Supports development of gentler, more effective moisturizers for xerosis-prone skin, potentially reducing irritation versus higher-active formulations.
Key Findings
- Supramolecular DOP–HA formed large sheet-like structures under scanning electron microscopy.
- Moisture absorption significantly improved after supramolecular assembly.
- The complex protected against cell drying damage in an in vitro model.
- In winter outdoor conditions (Beijing), it improved skin moisture, reduced roughness and scale, and favorably impacted TEWL.
Methodological Strengths
- Multi-scale evaluation (SEM morphology, in vitro cell model, and in vivo-like field tests including TEWL).
- Clear before–after comparisons pre- and post-supramolecular assembly.
Limitations
- Sample size and detailed human testing methodology not reported in the abstract.
- No randomized, controlled human trial presented.
Future Directions: Conduct controlled, randomized human studies comparing DOP–HA to HA alone and standard moisturizers, with longer follow-up and barrier biomarker endpoints.
BACKGROUND: Supramolecular technology has been widely applied in cosmetics due to its ability to enhance the stability of active substances and reduce their irritation potential. The synergistic interaction between polysaccharides can produce new products with characteristics and rheological properties that make them suitable for various applications. OBJECTIVE: The supramolecularly assembly of Dendrobium officinale polysaccharide (DOP) and hyaluronic acid (HA) was produced, and its moisturizing effect was verified to provide a basis for the application of supramolecular technology in cosmetic functional raw materials. METHODS: The supramolecular structure of polysaccharide assembly samples was verified through scanning electron microscopic observation. Moisture absorption and the ability of samples to resist cell drying damage before and after supramolecular assembly were evaluated by moisture absorption experiments and a cell drying damage model, respectively. Furthermore, this study validated the moisturizing effect of the supramolecular compositions during their application in cosmetics through tests of skin moisture content in extremely dry environments (during the winter season of Beijing, China), skin roughness and scale index, and trans epidermal water loss. RESULTS: The supramolecular composition appeared as a large sheet-like structure under a scanning electron microscope. Further, the supramolecular composition had significantly improved moisture absorption performance and could effectively resist cell drying damage. In an extremely dry environment, the composition showed excellent moisturizing performance and effectively improved skin scale and roughness. CONCLUSIONS: The supramolecular assembly of DOP and HA has a synergistic moisturizing effect; thus, it can be expected to have a good moisturizing effect when applied to cosmetics.
