Step-by-step explanation:
Function of Moisturizers
Moisturizers are cosmetic preparations used to protect, moisturize, and lubricate the skin. They have several functions:
- Hydration: Moisturizers provide temporary hydration to the skin by containing water, which helps moisturize and soften the skin.
- Barrier Formation: Moisturizers form a barrier on the surface of the skin, preventing the loss of water and keeping the skin hydrated.
- Relief of Itching and Inflammation: Some moisturizers contain active ingredients like occlusives and humectants, which can alleviate itching and inflammation of the skin. Occlusives form a coating on the skin, preventing water loss, while humectants help draw moisture into the skin.
- Additional Ingredients: Moisturizers may also contain antioxidants, ceramides, emulsifiers, fragrances, and other components that can provide additional benefits to the skin.
