Estrogens also regulate GAGs in the skin, and losing these hormones results in dehydrated, itchy skin. Estrogenic loss also reduces the number of blood vessels in the skin, resulting in pale skin with a lack of nutrients traveling to the skinâs surface.2 In all, we get pale, thin and dry skin.
Joseph Black recognized magnesium as an element in 1755. It was isolated by Sir Humphry Davy (1778-1829) in 1808 almost 200 years after its discovery. He electrolysised mixture of magnesia (magnesium oxide, MgO) and mercuric oxide (HgO). Davy's first suggestion for a name was magnium but the name magnesium is now used.
The alkali metal was discovered by Sir Humphry Davy in 1807 in England. The discovery of the element happened when he used electrolysis to process caustic potash. According to records, it is the first alkali metal to be discovered using electrolysis. At first, there are no distinctions between potassium and sodium.
