Why do Europeans and Americans have freckles and rough skin? But it looks rosy.

It's simple because people of different races have different skin colors. Europeans and Americans are mostly white, and their skin color is very white. Therefore, the skin contains very little melanin, which is pitifully small. It is precisely because there is less melanin that the skin color is white and ruddy, which is easier to penetrate and visible to the naked eye. There is less melanin, although the skin color is white, but the skin without melanin protection is very fragile, and it is difficult to resist external damage, including air, sunlight and artificial preparations, so it will be rough and even freckles over time. So, there are advantages and disadvantages, depending on what you think!
