Dry skin is one of the main health problems of the skin, characterized by the loss of fluids and nutrients. Dry skin can be caused by external factors such as environmental agents, smoking, etc. and internal factors such as aging (senile xerosis) or other diseases. Prevention involves proper measures such as avoiding aggravating environmental agents and adequate skin moisturization and hygiene. When skin becomes very dry it can become extremely scaly, rough and itchy, tending to form small superficial cracks.
