Skin care refers to the practice of maintaining the health and appearance of the skin through regular cleansing, moisturizing, and protection from environmental factors like sun exposure. A good skincare routine typically includes cleansing to remove dirt and impurities, exfoliating to remove dead skin cells, moisturizing to keep the skin hydrated, and using sunscreen to protect against harmful UV rays. Proper skin care helps improve skin texture, prevent premature aging, and maintain a healthy glow.
