A skin care routine is a series of steps designed to maintain and improve the health and appearance of the skin. It typically includes cleansing, exfoliating, moisturizing, and applying sunscreen. Each step serves a specific purpose, such as removing dirt and oil, sloughing off dead skin cells, hydrating the skin, and protecting it from harmful UV rays. The products used in a skin care routine can vary based on skin type, such as oily, dry, or sensitive skin. Common products include cleansers, toners, serums, and moisturizers. Establishing a consistent routine can help achieve clearer, healthier skin over time.
