Skin care refers to a range of practices and products that are designed to maintain healthy skin, prevent or reduce the appearance of wrinkles, blemishes, or other imperfections, and protect against environmental factors such as sun exposure. This can include regular cleansing, exfoliation, moisturizing, and applying topical treatments as needed. Skin care routines may vary depending on an individual's skin type, age, lifestyle, and other factors, but the overall goal is to promote healthy, radiant skin through proper maintenance and protection.
