A "clean-up" refers to the process of tidying or refreshing a specific area or task. In beauty and skincare, a clean-up typically involves a facial treatment aimed at removing impurities, dead skin cells, and excess oil. It often includes steps like cleansing, exfoliating, steaming, and moisturizing to give the skin a fresh and rejuvenated appearance. Clean-ups are usually shorter than full facials and can be done regularly to maintain healthy, glowing skin.
