Objectives: Skin aging is subject of many studies in esthetic surgery including several morphological changes like decrease of epidermis thickness and of cell proliferative potential. ASC, mesenchymal stem cells derived from adipose tissue, have been used in regenerative and reparative surgery as well as anti-aging solution. The aim of this study was to highlight the influence of ASCs on skin a...
Studies in model organisms suggest that aged cells can be functionally rejuvenated, but whether this concept applies to human skin is unclear. Here we apply 3'-end sequencing for expression quantification ("3-seq") to discover the gene expression program associated with human photoaging and intrinsic skin aging (collectively termed "skin aging"), and the impact of broadband light (BBL) treatmen...
Loss of fine skin patterning is a sign of both aging and photoaging. Studies investigating the genetic contribution to skin patterning offer an opportunity to better understand a trait that influences both physical appearance and risk of keratinocyte skin cancer. We undertook a meta-analysis of genome-wide association studies of a measure of skin pattern (microtopography score) damage in 1,671 ...
Skin aging is influenced by many factors including ultraviolet radiation, excess alcohol consumption, tobacco abuse, and environmental pollution. Age-related skin changes are the result of genetically programmed changes (intrinsic factors) and environmental wear-and-tear on the skin (extrinsic factors). This article also provides information about wrinkles development and the approaches to stim...
The free radical theory of aging postulates that the production of mitochondrial reactive oxygen species is the major determinant of aging and lifespan. The skin represents an excellent and accessible model organ to study aging that is characterized by atrophy, wrinkle formation, reduced tensile strength and impaired wound healing. Oxidative stress as a consequence of an imbalance in prooxidant...
The quest for youth and beauty is an ongoing one. No organ conveys youth and beauty to the extent that skin does. Advances in research over the past several decades have yielded a tremendous amount of information on the molecular pathways involved in both intrinsic aging (natural) and extrinsic aging (photoaging). In this article, we aim to describe the molecular pathways that lead to an aged a...
