Answer 1
January, 2021According to my own observations, tanning by the sea is softer, more beautiful, in contrast to the city, especially in those cities where the sun is hot in earnest :(
Answer 2
January, 2021The persistence of tanning depends on how deeply the light penetrated into the thickness of the skin and to what depth it acted. The deeper the pigment-producing skin cells are located, the longer they will peel off (and the tan will be washed off).
Now let's look at the process of pigment production in the skin depending on the intensity of radiation and its direction. It is this - intensity and incidence at an angle - that distinguishes exposure to sunlight at high latitudes or closer to the equator.
When intense rays strike the skin directly, they quickly cause active production of pigment in the surface layers of the skin. As a result, the deeper layers become protected from the effects of rays (light-absorbing pigment protects them). They remain unpigmented.
In the north, the intensity for the rapid formation of pigment protection in the surface layers is not enough and the rays slowly but surely affect the cells of deeper layers. They also produce pigment. As a result, the pigmented layer of the kosha is thicker and takes longer to exfoliate.
