Screening sunscreens: Protecting biomechanical barrier function of skin from solar ultraviolet radiation damage
from Society of Cosmetic Scientists via PubMed
Solar ultraviolet radiation is ubiquitous in human life and well-known to cause skin damage that can lead to harmful conditions, such as erythema. Although sunscreen is a popular form of protection for some of these conditions, it is unclear if sunscreen can maintain the mechanical barrier properties of skin. The objective of this study is to determine if in vitro thin film mechanics techniques adapted for biological tissue are able to characterize the efficacy of commonly used UV inhibitors and commercial sunscreens to protect the biomechanical barrier properties of stratum corneum from UV exposure.
