What does the term "redox" stand for?

Enhanced oxidation
Reduction-oxidation
Radical oxidation
Reactive oxygen derivatives

The correct answer is: Reduction-oxidation

The term "redox" is a shorthand for "reduction-oxidation." In chemistry, a redox reaction is a type of chemical reaction that involves the transfer of electrons between two species. In these reactions, one substance is oxidized (loses electrons) while another is reduced (gains electrons). This simultaneous occurrence is fundamental in various biological and chemical processes, including metabolism, the corrosion of metals, and even in certain skin care treatments aimed at improving skin health. Understanding redox reactions is crucial for estheticians as they can be involved in procedures that rely on oxidative agents or antioxidants to affect the skin. For example, many skincare products and treatments utilize redox principles to enhance skin rejuvenation or to combat oxidative stress, which is linked to aging and skin damage.
