Spring "break" came, went, and is gone. All I have to show for my last "break" from college (EVER!) is a bunch of new freckles. Now i know that freckles are the first sign of sun damage, but man do i love them. I have 3 favorites. --which yes is weird -- but all the same.
Biology of freckles:Freckles can be found on anyone no matter their genetic background; however, having freckles is genetic MC1R gene variant.The formation of freckles is triggered by exposure to sunlight. The exposure to UV-B radiation activates melanocytes to increase melanin production, which can cause freckles to become darkerand is related to the presence of the dominant melanocortin-1 receptor
