Effectiveness and tolerance of multicorrective topical treatment for infraorbital dark circles and puffiness.

BACKGROUND: Treatment of infraorbital dark circles and under-eye puffiness is challenging due to its multifactorial nature and lack of broadly applicable, effective treatments. A daily skincare treatment option that is multimodal, effective, and tolerable across a broad patient population is an unmet need. AIM: A multicorrective topical eye cream (MTEC) formulated with Tetrahexyldecyl (THD) ascorbate (vitamin C), prebiotic Inula Helenium, bioavailable peptides, botanical extracts, chrysin, and caffeine is hypothesized to improve the appearance of infraorbital dark circles and under-eye puffiness by targeting microvasculature congestion and permeability, melanin accumulation and hemoglobin degradation-related pigmentation, and skin health. METHODS: An IRB approved, open-label, 12-week clinical study set out to evaluate the efficacy and tolerability of the MTEC across a broad patient population including varying ethnicities and Fitzpatrick Skin Types (FST). Female subjects (n = 40) ages 35-60 years old, with moderate-to-severe under-eye dark circles, moderate under-eye puffiness, and mild-to-moderate fine lines were enrolled into the study. Objective (Chromameter, VISIA® imaging, and Laser Doppler) and subjective assessments (clinical grading and self-assessment questionnaire) were conducted at baseline and post-baseline timepoints. RESULTS: Thirty-seven subjects completed the study, and the MTEC efficaciously demonstrated short-term and long-term improvements in objective and subjective assessments across a broad patient population. Specifically, the MTEC demonstrated significant improvement of infraorbital dark circles, mainly by the reduction in microvasculature congestion and permeability, melanin, and hemoglobin degradation-related pigmentation. CONCLUSION: Topical application of the MTEC may offer an effective and tolerable treatment option for infraorbital dark circles and puffiness.

Antioxidant Skincare Treatment for Hyperpigmented and Photodamaged Skin: Multi-Center, Open-Label, Cross-Seasonal Case Study.

Objective: The objective of this study is three-fold. Firstly, to evaluate an enhanced vitamin C serum (eVCS) and its' combination with a retinol-bakuchiol serum (RBS) on pigmentation in vitro. Secondly, to evaluate the effect of the eVCS on skin function ex vivo. Lastly, to evaluate eVCS and RSB in the treatment of facial hyperpigmentation and overall photodamage across a range of opposing environments. Methods: MelanoDerm™ tissues were topically treated with the eVCS, and a eVCS and RSB blend for 14 days, and then a melanin assay was performed. Surgical waste facial skin explants were incubated with the eVCS or control for five days and then fixed and stained for skin physiology and structure. A 12-week, IRB approved, study on female subjects (n=29, aged 35 to 65) with moderate global facial hyperpigmentation and overall photodamage was completed. Clinical assessment, tolerability measurements, and subject-assessments were performed baseline at Weeks 6, 8, and 12. Investigator Global Aesthetic Improvement Score was completed at Week 12. Results: The eVCS-treated facial skin explants achieved a significant 145 percent collagen increase compared to control. The eVCS-RSB combination proved synergistic in reducing melanin compared to the eVCS alone. The eVCS-RSB combination demonstrated significant clinical improvement at all timepoints and was well tolerated. Subject responses were favorable and GAIS score of 3.0 was achieved at Week 12, indicating an improvement. Limitations: Limitations include lack of placebo or vehicle control. Conclusion: The product pairing, eVCS and RSB, offers patients an efficacious and well-tolerated treatment to target pigmentation and photodamage. Clinical Trial: This study, Pro00050557, was approved by Advarra IRB (Columbia, Maryland) and submitted to ClinicalTrials.gov #: NCT05423873.

A multi-functional anti-aging moisturizer maintains a diverse and balanced facial skin microbiome.

AIMS: To assess the effect of a 28-day skincare regimen in healthy female subjects on the facial skin microbiome composition and to determine whether the skincare regimen including a gentle cleansing lotion, a multi-functional anti-aging moisturizer formulated with prebiotics and postbiotics at skin neutral pH, and bland sunscreen pushed the microbiome to a healthier state and improved skin aging measured by self-assessment and clinical photography. METHODS AND RESULTS: The study protocol was in accordance with the EU Scientific Committee on Consumer Safety (SCCS) guidance and met all international standards. In all, 25 female subjects between 35 and 65 years old with Fitzpatrick skin types I-VI, moderate crow's feet wrinkles and global face photodamage were enrolled. After 28 days, the skincare regimen improved microbial facial diversity and shifted the microbiota composition when compared to baseline. CONCLUSIONS: After 28 days, the skincare regimen treatment shifted the distribution of the facial skin microbiome, positively influencing the skin microbiome diversity and balance, to promote long-term skin health and protect from further skin aging. SIGNIFICANCE AND IMPACT OF THE STUDY: These results suggest that incorporating prebiotics and postbiotics into a skincare regimen may have a positive impact on the facial skin microbiome in healthy women.
