RESUMO

Purpose:  This prospective, single-center study aims to evaluate the safety and effectiveness of NEAUVIA Intense, a PEG cross-linked polymeric hydrogel, in correcting moderate-to-severe nasolabial folds (NLF) in a routine clinical setting. The study investigates the aesthetic outcomes, patient satisfaction, and adverse events associated with the injectable filler. Patients and Methods: Seventy patients were initially enrolled, with 60 meeting study parameters. The post-market study involved a single session treatment, employing NEAUVIA Intense on each side of the NLF. Assessments utilized the Modified Fitzpatrick Wrinkle Scale (MFWS), Global Aesthetic Improvement Scale (GAIS), and Visual Analogical Scale (VAS). Results:  The study demonstrated a statistically significant improvement in tissue depression immediately post-injection (p < 0.001), with sustained effects up to 6 months. MFWS assessments revealed that responder patients were 96.6% immediately after treatment, 76.6% one month, 48.3% after 3 months, and 28.3% at 6 months (p < 0.001). Additionally, there was a significant change in the frequency distribution of MFWS scores post-treatment (p < 0.001), with the majority of patients experiencing improvement in tissue depression. Maximum improvement was observed at 30- and 90-days post-treatment based on GAIS assessments. Patient and physician satisfaction, measured by VAS, remained stable over time, with fluctuations at 4 and 24 weeks after treatment (p < 0.001, Anova; p < 0.05, Wilcoxon). Throughout the entire follow-up duration of the patients enrolled in the study, no adverse effects related to the use of the product were observed. Conclusion:  NEAUVIA Intense proved to be an effective solution for correcting NLF, providing significant and lasting improvements in tissue depression and aesthetic outcomes. The study underscores the necessity for continuous assessment in aesthetic medicine to align outcomes with evolving patient expectations and optimize long-term results. The findings contribute to the understanding of this specific hydrogel filler and highlight the broader context of injectable fillers in comprehensive facial aesthetic strategies.

RESUMO

BACKGROUND: Age-associated changes in epidermal hydration, pigmentation, thickness and cell renewal influence skin appearance and can lead to laxity, dryness and poor skin tone. The aim of this pilot study was to assess the synergistic effects of a new bipolar radiofrequency plus non-crosslinked hyaluronic acid (HA) mesotherapy protocol compared with radiofrequency alone on skin appearance and markers of epidermal function. METHODS: This prospective, single-center, split-face pilot study recruited women aged 25-65 years with dryness and laxity of the facial skin defined by a trans-epidermal water loss (TEWL) value of ≥26 g/m2/h. Subjects were treated with a bipolar radiofrequency device on both sides of the face. This was immediately followed by needle hyaluronic acid (HA) treatment on one side of the face with 2.5 mL of a non-crosslinked HA. Photographic documentation, analysis of epidermal barrier function parameters, and high frequency (HF) ultrasound analysis were performed prior to treatment and at 28 days. RESULTS: Twenty female subjects with a mean age of 46 (range 29 to 54) years and dry and lax facial skin were included. TEWL was reduced and skin hydration improved to a greater extent with the combined radiofrequency plus mesotherapy protocol compared with radiofrequency alone (-5.8% vs. +3.9% and +23.1% vs. +1.0%, respectively). The combined protocol was also associated with greater improvements in melanin (-7.5% vs. -1.5%) and erythema values (-7.2% vs. +3.0%), respectively. Ultrasound measures of epidermal thickness and epidermal density were greater after the combined protocol compared with radiofrequency alone (12.0% vs. 5.6% and 57.7% vs. 7.1%, respectively). Both treatments were well-tolerated. CONCLUSIONS: The combined bipolar radiofrequency and HA mesotherapy protocol provided greater improvements in skin hydration, firmness and tone compared with radiofrequency alone. The combination treatment was also associated with greater epidermal thickness and density and increased keratinocyte differentiation suggesting a synergistic effect of both treatments on epidermal homeostasis and barrier function. Both treatments were well-tolerated and led to improvements in facial appearance.

RESUMO

Mucous membrane pemphigoid (MMP) is a subtype of autoimmune subepidermal blistering diseases characterized by autoantibodies to structural components of the hemidesmosome primarily affecting mucous membranes. Inflammation-related progressive scarring can lead to serious complications, including blindness, and the disease may be associated with malignancy. Conventional immunosuppressive treatment is often insufficiently effective and limited due to side effects, warranting new therapeutic options ideally targeting both inflammation and extensively recalcitrant cicatrization. Heat shock protein 90 (Hsp90) is a cell stress-inducible chaperone required for the function of a large number of client proteins, and its pharmacological inhibition has proven to be effective and relatively safe in patients with cancer. Recent observations also suggest a promising role of Hsp90 as drug target in preclinical in vivo murine models of autoimmune diseases such as subepidermal bullous and fibrotic autoimmune disorders comprising epidermolysis bullosa acquisita and systemic sclerosis, respectively, which exhibit some pathophysiological features reminiscent of MMP. This article thus hypothesizes that Hsp90 blockade could represent a double-edged sword in MMP treatment by targeting pathogenic factors of inflammatory blister and fibrosis formation. Moreover, Hsp90 inhibitors could even be proclaimed as a triple-edged sword in case of an underlying malignancy. Future studies investigating the role of Hsp90 in MMP are needed to clarify whether Hsp90 inhibition could become a novel treatment approach for patients with this potentially devastating disease.
