What is oxidation in chemical terms?

1. Loss of electrons

2. Gain of oxygen

3. Both A and B

4. None of the above

The correct answer is: Both A and B

Oxidation in chemical terms refers to a reaction in which a substance loses electrons and often involves the addition of oxygen. When a substance oxidizes, it increases its oxidation state. The process of oxidation is fundamental to many chemical reactions, including those that occur in skincare products. In the context of esthetics, understanding oxidation is important because it can affect how ingredients in products react and how they interact with the skin. The gain of oxygen is frequently associated with oxidation in chemical reactions, exemplified by processes such as rusting of metals or combustion reactions. Therefore, both the loss of electrons and gain of oxygen are underlying principles that define oxidation. This duality is captured in the correct choice, reinforcing the understanding that oxidation encompasses both aspects simultaneously.
