Ultraviolet

Both UVA and UVB destroy vitamin A in skin, which may cause further damage. UVB light can cause direct DNA damage. In defense, our body releases a pigment called melanin, which is produced by cells in our skin called melanocytes. Melanin absorbs ultraviolet light and dissipates it as heat. According to Gary Chuang, assistant professor of dermatology at Tufts University School of Medicine says,” Melanin is a natural sunscreen. When your body senses sun damage, what it does is it starts sending…

the sun. Tanning produces more of the pigment melanin, which helps skin cells absorb the ultraviolet radiation of the sun's rays…

We all know that we have our own unique fingerprints but did you know that you can make sun prints? You may be wondering what a sunprint is, a sunprint is like a unique type of photo made with special sunprint paper that with the help of the sun creates a permanent image. A sunprint is formed when a chemical reaction happens with chemicals inside the paper,but before we talk about that, here is how you make a sunprint. You can make a sunprint by placing an object on a sheet of sunprint paper,…

possible issues, than other body systems. Skin cancer is a growing issue in this country. Cutaneous Squamous Cell Carcinoma is one of the most common forms of skin cancer. Our very own sun can cause this cancer, also causing it to advance from the Ultraviolet Rays. In studying Cutaneous Squamous Cell Carcinoma (SCC) through DNA Methylation profiling, two subclasses of SCC have been found to have two distinct cell origins. Actinic Keratosis (AK) are UV-induced precancerous corruption of cells…

actinic elastosis is a condition associated with chronic ultraviolet damage superimposed on aging skin. It presents as a yellowish thickened appearance to the skin which is bumpy and covered with furrows. The condition is due to the accumulation of disordered elastic tissue in the upper and middle layers of the dermis, which are most susceptible to sun exposure. In this way solar elastosis is a biological indicator of the degree of ultraviolet-induced skin damage the individual has sustained,…

structure. A healthy and well-being is what we want and this is an excellent way to do that. UV Rays The Sun is a very nasty monster that can cause catastrophic damage to our skin. The most damage, of course, comes from the ultraviolet radiation from the sun’s rays. Ultraviolet is an electromagnetic radiation and is present in sunlight constituting about 10% of the total light output of the Sun. Even though UV rays make up only a very small portion of the sun’s rays, they are the main cause of…

Background It is well recognised that exposure to solar ultraviolet (UV) radiation is a major cause of skin cancer (World Health Organisation IARC 1992). Worryingly recent studies have shown that UV levels have increased due to the reduction of stratospheric ozone (World Meteorological Organization 2010). The United Nations Environment Programme (UNEP) predicts that in the event of a 10% decrease in stratospheric ozone an additional 304,500 cases of skin cancer will occur globally each year…

may encounter from the sun. That is why caucasians are more immune to skin cancer because they do not produce enough melanin as someone with darker skin does. Most people believe that people with dark skin cannot get skin cancer which is false. Ultraviolet radiation is how one can get skin cancer. If an individual is exposed to the sun for long periods of time, he or she has a good chance of getting skin cancer, regardless of their skin color.…

photosensitivity, pigmentary changes, and malignant tumor development. This affliction received its name from its characterized dry, pigmented skin. The symptoms are caused by an irregularity in DNA repair as a result of cellular hypersensitivity to ultraviolet radiation. XP usually presents itself during infancy and early childhood. Just a few minutes in the sun can cause serious sunburn with redness and blistering. People with this unique condition have an expanded risk of developing skin…

Hunter Baker Furlong 1 FF Health Skin Cancer Skin cancer is cancer cause from sun's ultraviolet rays when you are exposed to them too much. Skin cancer is the abnormal growth of skin cells. Also don't be tricked you can get skin cancer on areas of the body not exposed to the sun, and no skin color does not change if you can get this type of cancer or not. There are 3 main types of skin cancer but also 5 other kinds that are rare and cause only 1% of all skin cancer with the 5 combined.…
