The skin is the organ of the human body larger. As the body develops therefore the functions of nutrition, assimilation and elimination.
So it is important what you eat because the food eaten will be catabolized, ie, becoming smaller, to reach out to the capillaries that are supplying the entire skin.
These capillaries also transport oxygen to be used to synthesize energy and having a “fuel” available to perform various functions.
You have two arguments and to raise awareness of the importance of acquiring food and physical exercise in aesthetic issues.
The activity is best the aerobic, or in the presence of oxygen, which is what most stimulates increased blood circulation to all muscles of the body, thereby enabling the elimination of toxins and cell renewal.
Also, cells are formed in about 75% water, hence the importance of hydration for freshness.
Finally, it is important that the skin ‘breathe’, that is, not too warm or keep it covered, because it alters the process of eliminating toxins, and the skin becomes flabby and sick.
