How often should oily skin undergo exfoliation?

For oily skin, exfoliation twice a week is considered ideal because it helps to remove excess dead skin cells and prevent clogged pores, which can lead to acne and dullness. Oily skin tends to have a thicker stratum corneum due to the higher sebum production, making it more prone to build-up. By exfoliating twice a week, the skin can maintain a clear and more refined texture, and it allows for better absorption of skincare products.

This frequency strikes a balance that promotes skin health without causing irritation. Over-exfoliation, such as doing it every day, can strip the skin of necessary oils and may trigger an overproduction of sebum as the skin tries to compensate for the loss of moisture. Similarly, exfoliating once a month may not provide enough benefit to address the needs of oily skin. Therefore, exfoliating twice a week is the most effective strategy for managing oily skin while ensuring it remains healthy and vibrant.
