Detailed answer

To prevent whiteheads, it is recommended to exfoliate 2-3 times per week. Exfoliation helps to remove dead skin cells and unclog pores, reducing the chance of whitehead formation. However, it's essential to avoid over-exfoliating, as it can irritate the skin and lead to more breakouts. Choose a gentle exfoliator suitable for your skin type and always follow up with moisturizer to keep the skin balanced and hydrated. Additionally, maintaining a good skincare routine that includes cleansing twice daily, using non-comedogenic products, and keeping the skin clean can further prevent whiteheads and maintain overall skin health.
