How genetics affects your skin

The skin is the largest organ in the body, and it’s also one of the most complex. The skin’s job is to protect us from the environment and everything in it, including UV rays, bacteria, and toxins. But did you know that your skin can also give insights into your health? For example, certain genetic conditions can cause changes in the skin that may be an indication of a more serious underlying condition. By working with an experienced team of professionals at Plantation Dermatology in Plantation, FL, you can learn more about the role genetics play in the health of your skin.

Ways in which genetics affect the skin

  • Allelic exclusion. One way genetics can affect the skin is through allelic exclusion. This process occurs when specific genes are not expressed due to mutations or other changes. This can lead to skin problems, such as increased susceptibility to infection or inflammation.
  • Gene flow. Another way genetics affects the skin is through something called gene flow. This is when genes from one population are introduced into another population. It can happen when two different species interbreed or when humans migrate to new areas and come into contact with varying populations of people. Gene flow can also cause problems if the genes introduced are not well-suited for the new environment. For example, if a person with a genetic mutation that causes increased sun sensitivity moves to an area with strong sunlight, they may be more likely to develop skin cancer.
  • Natural selection. Another reason why genetics affects the skin is because of something called natural selection. This is when specific genes are more likely to be passed on to future generations because they offer some advantage in the environment. For example, people who have a genetic mutation that makes them less susceptible to skin cancer are more likely to survive and pass on that mutation to their children.
