Why Is Silica In My Product? - The Dermatology Review

Silica, also known as silicon dioxide, is an oxide of silicon, the 14th element on the periodic table of elements After oxygen, silicon is the second most abundant element in the Earth’s crust, however, it very rarely occurs in nature as its pure form, rather, 90% of the Earth’s supply of silicon occurs as silica
