Genetic Basis of Rosacea
Rosacea is a common disease characterized by inflammation and vascular abnormalities of the facial skin and ocular surface. The exact pathogenesis of papulopustular rosacea is not well understood and current methods to treat this disease are often unsatisfactory. The purpose of this study is to develop gene expression profiles of papulopustular rosacea compared to those of normal skin. The investigators hope to better understand the abnormal gene functions that might contribute to this condition. This understanding may lead to the development of additional and better treatments for rosacea.
Discovery of Effects of Retinol on Human Skin Aging in Individuals of East Asian Descent
There has been increasing evidence for different rates of natural aging in humans and one of the best organs to study human aging is skin. Studies have demonstrated anti-agingeffects of topical agents (such as creams, gels, lotions, or ointments) and one of them, retinol or vitamin A, was shown to decrease fine wrinkling in skin of older individuals. Additionally, studies of retinol in humans have largely occurred in white populations and so this study aims to focus on skin aging in individuals of East Asian descent as they represent a majority of the world population. This study aims to better characterize the molecular basis of rejuvenation effects and to potentially discover new topical agents with similar and/or more effective preservation of skin youthfulness.
