Really regardless of race each person’s palms and soles become lighter in color. Due to the difference in tone, this situation is more evident in blacks.

In addition, the lines in these areas are still different from the light colors in these areas. gets dark. For this reason, the lines on the palms and soles of black people are much clearer.

Our skin is made up of layers called stratum corneum, epidermis, and dermis from the outside in.

The stratum corneum is the outermost layer of the skin and is made up of dead skin cells. This part also provides protection against harmful rays. The epidermis is where melanin is produced/stored. here melanocyte concentration It also provides protection from harmful rays.

Our skin color It is controlled by melanin produced by cells called melanocytes. Dark-skinned people have a higher concentration of melanin. The reason for this is that our skin has developed a shield against the sun in the process of evolution.

For this reason, the skin tone even darkens if you go to warm regions.

In the evolutionary process, people there have adapted to the environment due to the high temperatures in Africa. african bodies, to protect themselves from the sun’s rays formed too much melanin in their skin.

After this adjustment genes are passed on to the next generation. That is why today’s Africans have black skin. As you move away from the warm areas, the skin tone will shift to white as this natural shield is no longer needed.

This feature, which protects us through millions of years of evolution, can even come into play within a few hours, causing our skin to darken.

of the stratum corneum So fat is good. The thicker it is, the more we are protected from harmful rays. Our skin on the palms and soles has a thicker stratum corneum compared to other parts of the skin and therefore does not require a large concentration of melanocytes.

good “if it’s thick here, you don’t need a lot of melanin” our body always keeps these areas white.
