Xylose is the second most abundant monosaccharide in nature, and gallic acid (GA) has properties of antioxidant, anti-inflammatory and anti-bacterial. Hence, the gallate xylose (GX) polymers were synthesized from d-xylose and gallic acid for skin care applications in this paper. Then, the structure, generation mechanisms and the antioxidant activity of the generated polymer were studied. It got the results that: The generated GX polymers have strong antioxidant properties, yielded in 80.1% of GA mass. The DPPH scavenging activity was over 80.0% under the polymer's solution over 0.2 mg/mL. Moreover, the reaction mechanisms of DPPH removal were explained in a new theory based on Mass spectral analysis. Therefore, it demonstrates that the GX polymers of is a potential antioxidant material for skin care products, and it does contribution to the theory of DPPH removal for application in the fields of chemistry, biology and medicine researches.

Melanoma is the fifth most common skin cancer in the UK, accounting for 4% of all new cancer cases, with a predicted 7% increase in incidence between 2014-35. In parallel, since the initial publication of the Melanoma NICE Guidelines in 2015, there has been a paradigm shift in the management of the disease, with the introduction of effective systemic therapies. These innovations have reshaped the management of melanoma throughout the patient journey, and improved clinical outcomes.

While convex skin barriers have been used in patient care for decades, regulatory bodies and manufacturers have not established consistent parameters for measuring the most essential characteristics of a convex skin barrier. A transdisciplinary panel of manufacturers, engineers, marketing specialists and clinical subject matter experts from the United States was convened to address this gap. An initial consensus meeting was held to establish consensus around measurement parameters for 5 characteristics of convex skin barriers: depth, slope, flexibility, compressibility, and tension location.

Hazards to human and planetary health are present at every stage of the plastic life cycle, yet plastic production is projected to triple by 2060. This review focuses on three key areas: the life cycle of plastic, the impact of microplastics and their associated chemicals, along with recommendations to reduce plastic use. In dermatology, micro- and nanoplastics are especially problematic as they are present in over 90% of personal care products.

An 89-year-old male with a medical history of non-ischemic cardiomyopathy was initially admitted with acute hypoxic respiratory failure attributed to heart failure exacerbation. Aside from progressive dyspnea, a non-pruritic, non-painful rash and constitutional symptoms were reported. Initial work-up was remarkable for normocytic anemia, lymphopenia, mild hypercalcemia, and elevated inflammatory markers.
