Detailed answer

Excessive exfoliation involves scrubbing or using harsh physical exfoliants too frequently, which can lead to the removal of the top layer of the skin. This can temporarily make the pores appear smaller because the surface layer is smoother. However, over time, excessive exfoliation causes skin damage, thinning of the epidermis, and can disrupt the skin's natural barrier. As a result, the skin produces more oil to compensate for the loss of moisture and protection. The excess oil can then clog the pores, making them appear larger. Additionally, constant exfoliation can irritate the skin, leading to inflammation, which can also contribute to enlarged pores. Therefore, it is important to exfoliate in moderation and choose gentle exfoliation methods to maintain healthy skin and minimize pore size.
