Moisturizer is a product used to hydrate and soften the skin. It is often applied to the face and body to prevent dryness and irritation. The most common type of moisturizer is LOTION, which is a liquid or cream-based product that is applied to the skin. Lotions are typically composed of water, oil, and an emulsifier, and can contain additional ingredients such as fragrances, preservatives, and vitamins.
