1. Peptide-enriched hydrogel formulation for sensitive and damaged skin: from design to application testing.
The authors designed peptide-enriched hydrogels (NE1 with GHK; IM2) and showed stability, rapid peptide release (75–80% in hours), stimulation of keratinocyte migration, and favorable dermatological tolerance without irritant/sensitizing properties. Application testing suggested improvements in moisturization, redness, itch, and skin tension, supporting daily care use for sensitive or damaged skin, including post-radiation.
Impact: This work bridges formulation science and dermatological application, offering a peptide-based cosmeceutical with multi-layer evidence of safety and pro-regenerative activity relevant to patients with sensitive or radiation-damaged skin.
Clinical Implications: Provides a candidate daily-care formulation for sensitive or post-radiation skin; supports consideration of peptide-enriched hydrogels as adjunctive skincare pending randomized clinical trials.
Key Findings
- NE1 (GHK-containing) and IM2 peptides were formulated into stable hydrogels with preservative properties.
- Approximately 75–80% of each peptide was released within the first hours, indicating rapid bioavailability.
- p407 and the peptide-enriched composition stimulated HaCaT keratinocyte migration in vitro.
- Dermatological tests showed no irritant or sensitizing properties and indicated improvements in moisturization, redness, itch, tension, and irritation.
Methodological Strengths
- Integrated pipeline spanning peptide synthesis, physicochemical characterization, in vitro safety/activity, and human dermatological testing
- Quantified peptide release kinetics and cell migration assays using standard human keratinocyte model (HaCaT)
Limitations
- Human sample size and demographics not reported; no randomized or controlled clinical comparison
- Short-term assessments; long-term efficacy and safety remain undefined
Future Directions: Conduct randomized controlled clinical trials in patients with radiation-induced skin damage, define dose-response and durability, and elucidate mechanisms (e.g., GHK-mediated pathways) in vivo.
Various factors such as infections, wounds, and comorbidities can disrupt the skin's physiological function. Moreover, skin lesions can result from radiation therapy. We aimed to create a new cosmetic formulation with pro-regenerative properties that is specifically designed for patients with sustained skin damage, such as those who have undergone radiation therapy. In the first stage, NE1 and IM2 peptides were synthesized, and hydrogels were prepared. IM2 is a derivative of the IM peptide, while NE1 contains the bioactive GHK sequence. In the next stage physicochemical analyses were conducted, including the evaluation of peptide stability and the developed composition's microbial purity and packaging compatibility. In addition, in vitro safety and activity assessments were implemented on human skin cells. In the final step, dermatological tests were conducted on the participants. The results indicate that the cosmetic composition is stable, possesses preservative properties, and is safe in both in vitro and in vivo studies. Peptide release studies show that within the first hours, approximately 75-80% of each peptide is released, ensuring a rapid onset of action. Analysis of cell migration indicate that both p407 and the designed composition stimulate migration of HaCaT keratinocytes in vitro. Dermatological tests did not show any irritant and sensitizing properties. Application analyses revealed that the designed composition effectively moisturizes and takes care of sensitive skin, alleviates redness and the effects of rough skin, eliminates the sensation of itching and the effects of skin tension, and soothes irritation. This formulation can be used for the daily care of sensitive, allergic, or irritated skin.
2. Is Women's Happiness and Life Satisfaction a Determinant of Cosmetic Surgery Acceptance? Latent Profile Analysis.
In a cross-sectional online survey of 422 women using validated scales, happiness and life satisfaction correlated with each other but not with overall cosmetic surgery acceptance. Latent profile analysis identified three acceptance classes, with the high-acceptance class showing higher happiness and life satisfaction than others; sociodemographic variables were not significant predictors.
Impact: By combining validated measures with latent profile analysis, this study challenges simplistic assumptions about psychological predictors of cosmetic surgery acceptance and highlights heterogeneity relevant to patient counseling.
Clinical Implications: Preoperative counseling should not assume low happiness or life dissatisfaction as primary drivers of cosmetic surgery acceptance; instead, stratify by acceptance profiles and assess psychological well-being holistically.
Key Findings
- In 422 women, happiness and life satisfaction were positively correlated, but neither predicted overall cosmetic surgery acceptance.
- Latent profile analysis identified three acceptance classes (low, medium, high); the high-acceptance class had higher happiness and life satisfaction than others.
- Sociodemographic variables did not significantly predict acceptance levels in logistic regression.
Methodological Strengths
- Use of validated instruments with latent profile analysis to uncover heterogeneity
- Moderate sample size with multivariate modeling
Limitations
- Cross-sectional online survey limits causal inference and may introduce selection/self-report bias
- Findings may not generalize beyond the sampled population; predictors in regression were non-significant
Future Directions: Prospective, cross-cultural studies incorporating body image, stigma, and mental health measures; test whether acceptance profiles predict surgical decision-making and outcomes.
BACKGROUND: This study aimed to investigate the acceptance of cosmetic surgery among women in relation to their happiness and life satisfaction. METHODS: A cross-sectional, descriptive-correlational study employing latent profile analysis was conducted. An online survey was administered to 422 women between November 2024 and February 2025. Data were collected using a Sociodemographic Form, the Cosmetic Surgery Acceptance Scale, the Oxford Happiness Questionnaire-Short Form, and the Contentment with Life Assessment Scale. RESULTS: Participants reported moderate average levels of happiness, life satisfaction, and cosmetic surgery acceptance. Correlation analysis revealed a significant positive relationship between happiness and life satisfaction. However, neither happiness nor life satisfaction showed a significant overall correlation with cosmetic surgery acceptance. In the latent profile analysis, participants were divided into three different groups as low (Class1), medium (Class2) and high (Class3) in cosmetic surgery acceptance. In the analysis, it was found that of the three acceptance groups defined, the high acceptance group had higher scores for happiness and life satisfaction than the other groups. In the logistic regression analysis, it was seen that sociodemographic variables had the potential to increase cosmetic surgery acceptance levels, but it was not found to be statistically significant. CONCLUSION: Happiness and life satisfaction are interrelated but do not predict overall acceptance of cosmetic surgery. The high acceptance group exhibited greater psychological well-being, revealing the heterogeneity of acceptance. Sociodemographic variables did not prove predictive. The findings call traditional assumptions into question. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

3. Hyperdiluted Triamcinolone Injections for Nasal and Alar Contouring.
A structured 20-patient case series describes a standardized 10-point microinjection protocol of hyperdiluted triamcinolone acetonide (~1.3 mg/mL) for gradual nasal/alar soft-tissue thinning. Five sessions (every 3 weeks; 1.0 mL per session) yielded patient-reported GAIS improvements, and the authors propose a patient-level GAIS reporting framework for transparency.
Impact: Introduces a nonfiller steroid-based contouring approach that conceptually differs from volume-adding fillers and surgical rhinoplasty, addressing safety and indication gaps in minimally invasive nasal refinement.
Clinical Implications: Offers a potential option for selected patients seeking soft-tissue debulking rather than augmentation; requires careful dosing, anatomical precision, and counseling on risks (cutaneous atrophy, telangiectasia, hypopigmentation).
Key Findings
- Standardized 10-point microinjection protocol of hyperdiluted TAC (~1.3 mg/mL) was applied in 20 adults.
- Five sessions at 3-week intervals (1.0 mL per session) resulted in patient-reported GAIS improvements at final follow-up.
- Cumulative TAC dose per patient was approximately 6.5 mg, aiming for localized, gradual soft-tissue thinning distinct from fillers.
Methodological Strengths
- Structured protocol with standardized injection map and dosing
- Transparent patient-level GAIS reporting framework
Limitations
- Small, uncontrolled case series using subjective outcomes (GAIS) without objective volumetric measures
- Short follow-up and no comparative safety data versus fillers or placebo
Future Directions: Prospective controlled studies with 3D imaging and quantitative thickness metrics, dose-ranging and anatomical safety studies, and longer-term follow-up.
BACKGROUND: Demand for minimally invasive nasal contour refinement has increased, particularly among patients seeking subtle esthetic improvement without surgery or volume augmentation. While hyaluronic acid filler-based nonsurgical rhinoplasty can alter contour, it fundamentally adds volume and carries rare but severe vascular risks. In contrast, intralesional corticosteroids are known to induce localized soft-tissue thinning and have been used in postoperative rhinoplasty to manage supratip fullness, suggesting a potential role in nonsurgical soft-tissue contour modulation. OBJECTIVE: To describe a nonsurgical, nonfiller technique using hyperdiluted triamcinolone acetonide (TAC) microinjections for targeted reduction of nasal and alar soft-tissue fullness, and to present a structured case-series protocol with standardized Global Aesthetic Improvement Scale (GAIS) reporting. RESULTS: Twenty adult patients underwent a standardized 10-point microinjection protocol using hyperdiluted TAC (approximately 1.3 mg/mL), with 1.0 mL administered per session and sessions repeated every 3 weeks for a total of five sessions. The cumulative TAC dose per patient was approximately 6.5 mg. Outcomes were assessed using patient-reported GAIS at final follow-up. This manuscript provides a patient-level GAIS reporting framework and an illustrative results table to support transparent outcome documentation. The technique is conceptually distinct from surgical rhinoplasty and filler-based approaches, aiming for gradual, localized soft-tissue thinning through dose-minimized, distributed corticosteroid exposure.
