It is proved that people with red hair color have a low level of vitamin K, which contributes to healing wounds, and, as a result, poor blood clotting. And the unconditional plus of red-haired - their body synthesizes a lot of vitamin D, which significantly reduces the risk of developing bone diseases, such as osteoporosis and rickets. These people should be less located in the sun and always use protective cream: Pigment Feomelain under ultraviolet rays affects the skin in such a way that there are free radicals that contribute to the development of skin cancer (melanoma). This statement is fair not only for red-haired, but also for people belonging to the first and second phototype (with light skin, blond or light-rusia hair, green, gray or blue eyes).
The skin itself gives danger signals - carefully inspect your moles. Spend an imaginary axis on each of them. It will divide the "good" mole into two symmetric parts. In safe moles, the edging is smooth and smooth, the color is homogeneous. If you have noticed different color inclusions (for example, black dots appear on a light mole), most likely nothing to do with the mole. The more Molenia, the higher its chances to turn into melanoma. The appearance of any external changes (crusts, cracks, peeling, bleeding) should alert you.
