SILICON

In a study conducted in Brazil in 2016, the potential benefits of using silicone in skin and hair care were investigated. The research indicated that silicon plays a crucial role in activating hydroxylating enzymes and enhancing collagen synthesis in the skin.

This suggests that silicon may contribute to improving skin strength and elasticity. Furthermore, the study noted that silicone can enhance hair shine and potentially reduce the rate of hair loss. These findings highlight the potential positive effects of silicone in enhancing the health and appearance of both skin and hair.

Silicon is a remarkably abundant element, constituting approximately 27.7% of the Earth's mass, making it the second most abundant element on our planet, surpassed only by oxygen. In its natural form, silicon is rarely found uncombined, typically occurring as silicates and oxides, most commonly in the form of silica.

Commercially, silicon is primarily produced through a process known as reduction, in which sand is reduced with coal in an electric furnace. This process allows for the extraction and purification of silicon, making it available for various industrial applications and technological advancements.
