Melanocytes produce dark brown substance called melanin, which allows the sun's rays penetrate deeply into the skin layers as it would be detrimental. At the same time, the Sunday of the cells stimulated the generation of light, the skin becomes thicker and therefore more resistant to UV rays. It appears that the sun is really good for the skin. Well ... People with light skin does not have enough melanin-producing cells, their mechanism of sunscreen is not strong, and they are bued very quickly Sunday. UV rays are very strong biological effects, which can damage proteins and molecules also alter the genetic material that causes healthy cells into malignant. Therefore, the tanning is bad. One could say yes, but ... Sunday is good nutrition for health. The increase in blood flow to the skin, stimulates cellular regeneration, helps to combat acne scars and minor imperfections of the skin smooth.

This is also shown to reduce the appearance of wrinkles and help maintain skin tone. Coenzyme Q10 is a powerful antioxidant. It is found in meat, fish, cereals, eggs, beans and spinach. Human body makes its own CoQ10, but production decreases with age. Coenzyme Q10 has exceptional antioxidant properties.
