Some people's skin is naturally sun-protected
Due to genetic changes in some individuals their skin becomes automatically sunscreen and they are protected from the harmful effects.
This was revealed during a survey on the correlation between vitamin D and genetics. The study evaluated the genes of about 5 million people in the UK and was conducted under the supervision of John McGrath, a professor at the Brain Institute at the University of Queensland.
This research has revealed several genes that are associated with vitamin D. These genes are beyond color and affect the production of vitamin D. In short, these genes also enhance the whole process of vitamin D production. Experts have concluded that the HAL (histidine ammonia-lyase) gene transforms the skin internally into a sunblock or sunscreen and also protects against sunburn. In this way, some people can withstand the side effects of sunlight.
In total, 143 genes have been discovered in the gene that affects vitamin D deficiency. Experts say the research will keep them busy for years because a detailed study is yet to be done. On the other hand, knowing how to make vitamin D in your body will also help.
Every person's skin and eyes can be affected by the sun and other forms of ultraviolet (UV) rays. People with fair skin are much more likely to have UV damage to their skin (and skin cancer), although people with darker skin, including people of any ethnic origin, can also be affected.
For some people, the skin tans when it absorbs UV rays. Tanning is caused by an increase in the activity and number of melanocytes, the cells that produce the brown pigment called melanin. Melanin helps block harmful UV rays to some degree, which is why people with skin that is naturally more
Dark skin is less likely to get sunburned, while people with lighter skin are more likely to get sunburned. Sunburn can increase your risk of skin cancer, including melanoma. However, UV exposure can increase the risk of skin cancer even without causing sunburn.
Most types of skin cancer are caused by excessive exposure to ultraviolet (UV) rays. Most of this exposure comes from sunlight, but a certain amount can come from artificial sources, such as tanning beds and sunlamps. People who are too exposed to ultraviolet (UV) rays have an increased risk of skin cancer.
