Cleanse, or purify, refers to the process of removing impurities or contaminants from a substance. This can apply to various contexts, such as cleansing water to make it safe for drinking or purifying air to improve indoor quality. The goal is to achieve a state of cleanliness that promotes health and safety. In personal care, cleansing often involves removing dirt, oil, and makeup from the skin. Products like cleansers and toners are commonly used in skincare routines to maintain a clear complexion. Additionally, detox diets aim to cleanse the body by eliminating toxins through specific foods or fasting.
