Trends in Use of Prescription Skin Lightening Creams

The desire for an even skin tone pervades all cultures and regions of the world. Uniform skin color is considered a sign of beauty and youth. Pigmentation abnormalities can arise idiopathically with genetic predetermination, with injury and environmental exposures, and with advancing age, and can, therefore, be distressing to patients, leading them to seek a variety of treatments with professional assistance. In this short report, we describe the trends in the use of prescription lightening creams, particularly in patients with darker skin types residing in the US. Amongst 404 participants, skin hyperpigmentation had a moderate effect on patients’ quality of life, and the most common diagnosis associated with the use of a prescription product was melasma (60.8%). The most common agent prescribed was hydroquinone (62.9%), followed by triple combination cream (31.4%). It is the dermatologist’s duty to gauge the effect of the pigmentation disease on patients’ life in order to counsel, tailor, and decide on the most appropriate treatment option.

Estimation of Active Compounds Quantity from Pharmaceuticals Based on Ginkgo biloba

Ginkgo biloba is one of the most important sources of active compounds, mainly flavonoids and phenolic compounds. Due to its importance related to pharmaceutical practice, the making of a qualitative and quantitative method for the detection and quantification of active compounds from Ginkgo biloba pharmaceutical products is desirable. In this study, the content of biological active compounds from Ginkgo biloba products was estimated using cyclic voltammetry. The electrochemical determination of active compounds was carried out by using a screen-printed carbon electrode modified with carbon nanotubes. The studies regarding parameter optimization were made using solutions containing potassium ferrocyanide and catechol, respectively. In both cases, the redox processes of studied compounds was observed, which were controlled by the diffusion phenomenon. We analyzed two pharmaceutical products containing Ginkgo biloba, a RX product (recipe medicine requires a medical prescription to be dispensed) and an OTC (Over-The-Counter, which can be obtained without a prescription) product. The cyclic voltammograms of the two products showed two redox processes due to the antioxidant properties of the products. It was found that the RX product had a greater content of active compounds compared to the OTC product. Therefore, the voltammetric method has great utility for the determination of compounds with redox properties from pharmaceutical products containing Ginkgo biloba.
