What causes freckles?

Is it true that people with fair skin are prone to getting freckles? I wonder what causes freckles, perhaps because I do a lot of outdoor activities. I'm also curious about the difference between freckles and spots. They look like spots and spots, so it's confusing. I want to find out the cause of freckles and have clear skin. If I visit Maypure, please tell me the overall cause of freckles and how the treatment is done. I'm also curious about what I should do to manage freckles on a daily basis♡ I heard that you diligently eat and apply vitamin C, but it's not easy to manage;
