Cleansing is important before applying other skincare products because it removes dirt, oil, makeup, dead skin cells, and environmental pollutants that accumulate on the skin throughout the day. This clears the pores and prevents clogging, which can cause breakouts and other skin issues. Clean skin also allows other skincare products like toner, serums, and moisturizers to penetrate more effectively and work better. Additionally, cleansing helps balance the skin's pH and supports skin renewal by removing dead cells, leading to a smoother and healthier complexion. It also improves blood circulation and reduces inflammation, which benefits sensitive skin. Overall, cleansing prepares the skin to receive the full benefits of subsequent skincare treatments and helps maintain skin health and radiance.
