1. Valorization of Apple Pomace: Production of Phloretin Using a Bacterial Cellulose-Immobilized β-Glycosidase.
This study presents a sustainable, high-yield biocatalytic process that converts apple pomace phloridzin to phloretin using an extremophilic β-glycosidase immobilized on bacterial cellulose in a biphasic system. The approach demonstrates complete conversion under process conditions, enabling circular-economy valorization of agricultural waste into a high-value cosmetic active.
Impact: It offers a greener, scalable route to a widely used cosmetic active, potentially reducing costs and environmental impact while ensuring supply chain resilience.
Clinical Implications: While preclinical/industrial, more reliable access to phloretin may expand its dermatologic use (e.g., antioxidant, anti-inflammatory actives) with better quality control and sustainability.
Key Findings
- Developed a biocatalytic process converting phloridzin (apple pomace) to phloretin using AHeGH1 β-glycosidase immobilized on bacterial cellulose.
- Implemented a two-liquid phase system (water/2,2,5,5-tetramethyloxolane) enabling complete conversion under the reported conditions.
- Demonstrated a sustainable valorization route from agro-waste to a high-value cosmetic ingredient.
Methodological Strengths
- Immobilized enzyme design enabling reuse and process stability
- Biphasic reaction system improving conversion efficiency
Limitations
- Industrial scale-up parameters and long-term catalyst stability were not detailed
- Downstream purification and cost analysis were not fully described
Future Directions: Scale-up studies, lifecycle assessment, cost modeling, and comparative efficacy/quality profiling of biocatalytically produced phloretin versus conventional sources.
In the last decade, phloretin (PHL) has attracted increasing attention due to its remarkable biological properties, including antimicrobial, antidiabetic, cardioprotective, anti-inflammatory, immunomodulatory, and antioxidant effects, becoming a leading ingredient in the cosmetic sector. In this work, an efficient, cost-effective, and highly productive biocatalytic strategy for the preparation of natural PHL has been developed starting from its glycosylated form, phloridzin, one of the main flavonoid components of apple processing waste (apple pomace). The process involved the use of the extremophilic β-glycosidase AHeGH1 immobilized on bacterial cellulose films in a two-liquid phase reaction system (water/2,2,5,5-tetramethyloxolane), allowing for the complete conversion of 5 g L
2. A non-invasive way to enhance cosmetic efficacy by associating a cosmetic serum with a nanochip tapping.
In a split-face in vivo study of 60 women over 8 weeks, a nanochip tapping device significantly augmented the anti‑aging serum’s improvements in wrinkles, fine lines, radiance, and hydration versus serum alone, without compromising stratum corneum integrity. Participants reported ease-of-use and perceived benefits.
Impact: Demonstrates device–cosmetic synergy in a noninvasive, at-home context with objective improvements and safety, informing consumer products and clinical counseling.
Clinical Implications: Clinicians can counsel patients that nanochip tapping may safely enhance outcomes of topical anti-aging regimens; however, product/device specificity and longer-term effects should be considered.
Key Findings
- Split-face in vivo study (n=60) showed significant improvements with serum alone (p<0.001 across measures) after 8 weeks.
- Combining serum with a nanochip tapping device further amplified wrinkle reduction, nasolabial fold smoothness, and firmness.
- No adverse effects on stratum corneum integrity; high user acceptance and perceived benefits.
Methodological Strengths
- Within-subject split-face design controlling for inter-individual variability
- Objective multi-dimensional skin metrics with statistical testing and safety assessment
Limitations
- Randomization/blinding not described; potential bias
- Single product/device; generalizability and long-term durability unknown
Future Directions: Randomized, blinded split-face trials with longer follow-up, device parameter optimization, and exploration across diverse formulations and skin types.
BACKGROUND: Skincare cosmetics have long been central to daily facial care routines, while recent years have seen a surge in the popularity of home beauty devices. Consumers increasingly seek more effective and efficient results from their beauty regimens while also expressing concerns about the potential risks of certain beauty procedures. Although various technological devices have been developed to meet these demands, research on the interactions between beauty devices and cosmetic products remains limited. METHODS: This in vivo study was conducted on 60 Chinese women of different ages and skin types. An assessment of the impact of a specific home beauty device, used after a standalone referential and marketed anti-ageing serum, on enhancing facial skin attributes (wrinkles, fine lines, radiance and hydration) was conducted. The device-a nanochip tapping tool with an ultra-fine surface-was evaluated alongside the serum under a half-face protocol. The study compared the efficacy of serum application alone to that achieved with the combined serum-device regimen. RESULTS: Marked reduction in ageing signs was reported for the serum alone, particularly for wrinkles (p < 0.001), fine lines (p < 0.001), radiance (p < 0.001) and hydration (p < 0.001) after 8 weeks. When paired with the nanochip device, efficacy was significantly amplified and enhanced global wrinkle reduction, nasolabial fold smoothness and firmness. There were no adverse effects on SC integrity, confirming that the serum-nanochip application preserved the integrity of the skin. All subjects found the nanochip easy to use and indicated perceived benefits.
3. Modified inverted 'L' epicanthoplasty combined with incisional blepharoplasty for epicanthal folds and single eyelids: a clinical outcomes study.
In 100 women undergoing a modified inverted ‘L’ epicanthoplasty combined with incisional blepharoplasty, the overall effectiveness and satisfaction rates were 97%, with significant postoperative palpebral fissure improvements and only minor, conservatively managed complications.
Impact: Provides pragmatic, outcomes-focused evidence supporting a commonly sought aesthetic procedure with high satisfaction and low complication rates.
Clinical Implications: Supports the modified inverted ‘L’ epicanthoplasty plus incisional blepharoplasty as a reliable option for epicanthal folds/single eyelids, with attention to precise marking, gentle dissection, and careful closure to minimize scarring.
Key Findings
- Overall effectiveness rate of 97.0% with 60% significant and 37% moderate improvement.
- Patient satisfaction rate of 97.0%; only two minor complications managed conservatively.
- Postoperative palpebral fissure measurements showed significant improvement.
Methodological Strengths
- Standardized marking/incision technique with defined follow-up schedule
- Objective eyelid measurements combined with patient-reported satisfaction
Limitations
- Single-center, female-only cohort; no control or comparator technique
- Short follow-up (3 months); long-term scar quality and stability unknown
Future Directions: Prospective controlled or randomized comparisons versus alternative epicanthoplasty techniques with longer-term aesthetic and functional outcomes.
OBJECTIVE: To evaluate the clinical outcomes of a modified inverted 'L' epicanthoplasty combined with incisional blepharoplasty for correcting epicanthal folds and single eyelids in patients of Mongoloid descent. METHODS: This observational study included 100 female patients aged 20 to 38 years, who underwent the combined procedure from January 2018 to September 2024 at Ganzhou People's Hospital. The modified technique utilized a specific marking and incision approach to address the epicanthal folds and create a double eyelid, with an emphasis on minimizing scarring and optimizing aesthetic outcomes. Local anesthesia was used, followed by meticulous dissection, fixation of the medial canthal ligament, and careful skin closure. Postoperative care included pressure dressing and ice packs, with follow-up visits at 1 week, 1 month, and 3 months. The observed indexes included the total effectiveness rate, changes in palpebral fissure measurements, patient satisfaction, and the incidence of postoperative adverse events. RESULTS: The overall effectiveness rate was 97.0%, with 60.0% of patients showing significant improvement and 37% achieving moderate outcomes. Three patients (3.00%) were dissatisfied with the outcomes. Postoperative palpebral fissure measurements showed significant improvement. Follow-up assessments indicated a high patient satisfaction rate of 97.0%, with minor complications in two cases, which were managed conservatively. CONCLUSION: The modified inverted 'L' epicanthoplasty combined with incisional blepharoplasty is an effective and aesthetically pleasing procedure for correcting epicanthal folds and creating double eyelids. Its simplicity, minimal scaring, and high patient satisfaction make it a valuable approach in oculoplastic surgery.
