Molybdenum dusts and fumes, generated by mining or metalworking, can be toxic, especially if ingested (including dust trapped in the sinuses and later swallowed). [100] Low levels of prolonged exposure can cause irritation to the eyes and skin. Direct inhalation or ingestion of molybdenum and its oxides should be avoided.
Molybdenum deficiency refers to the clinical consequences of inadequate intake of molybdenum in the diet. The amount of molybdenum required is relatively small, and molybdenum deficiency usually does not occur in natural settings. [1] However, it can occur in individuals receiving parenteral nutrition.

Metals have been used in treatments since ancient times. The Ebers Papyrus from 1500BC is the first written account of the use of metals for treatment and describes the use of Copper to reduce inflammation and the use of iron to treat anemia. Sodium vanadate has been used since the early 20th century to treat rheumatoid arthritis.
Most molybdenum is excreted from the human body as molybdate in the urine. Furthermore, urinary excretion of molybdenum increases as dietary molybdenum intake increases. Small amounts of molybdenum are excreted from the body in the feces by way of the bile; small amounts also can be lost in sweat and in hair. [31] [32]

Galvanic treatment in the beauty industry has been described since at least the 1970s [15] and earlier. [13] Sometimes called galvanism, the treatment aims to improve the skin in two ways: (1) cleansing: a process called desincrustation, and (2) nourishing the skin condition, through an electro-chemical process [16] called iontophoresis [17] (also called ionisation). [18]
Changes in skin: This often looks like noticeable dryness, flaky, or scaly skin, especially around the eyes, nose, and mouth. Changes in nails: You may start to notice your nails becoming more ...
In the human body, water constantly evaporates from the deeper layers of the skin through an effect known as transepidermal water loss. By regulating its water content, human skin naturally maintains a dry, easily shed surface as a barrier against pathogens, dirt, or damage, while protecting itself from drying out and becoming brittle and rigid.
