Abstract

Skin cancer is one of the most common forms of cancer and thus a big public health problem worldwide. However, although it is well known that UV radiation is the main cause of skin cancer, there are currently only a few quantitative studies about the effects of UV radiation on the skin. One of the main objectives of the research project we are conducting is centered on the study of the change in elasticity and/or stiffness that the skin suffers after being irradiated with UV, parameters that are being analyzed and quantified with the aim of using these elasticity properties as a powerful clinic tool. Preliminary studies on the elasticity of animal skin samples aged inside a UV radiation chamber were conducted using Digital Holography Interferometry, a non-invasive optical technique that has been gaining importance as an alternative way to study elasticity properties, mainly due to its sensitivity and precision for measuring displacements and strains. Controlled sound waves were used to stimulate the skin samples, with the results suggesting that the longer it is exposed to UV radiation the greater is its increase in stiffness, confirming the importance of not selfoverexposing to solar radiation. The research work proposed in the project represents a great opportunity to contribute to the knowledge of other skin diseases as well as skin cancer. A deeper analysis of the change in elasticity between healthy skin and skin with cancer will be discussed in a later publication.
