Genetic studies have found that human skin color, eye expression, hair color and other characteristics are all influenced by chromosomes and genes. Among them, the gene mutation that causes skin spots may occur at the time of fertilized eggs, or it may be inherited by one parent.
So there is no direct relationship between past lives and people with spots in the sky. People with long spots don't mean they have had past lives, that's just a legend. People with long spots need to pay attention to sun protection and avoid irritation, especially spots that have become melanoma should be treated in time. If it is not treated and managed for a long time, it may seriously affect appearance and health.
