What is a common result of over-exfoliation?

Over-exfoliation refers to the excessive removal of dead skin cells from the skin's surface, typically through the use of physical scrubs, chemical exfoliants, or a combination of both. A common result of this practice is skin irritation and a compromised skin barrier.

When the skin is over-exfoliated, it can lead to increased sensitivity, redness, inflammation, and the potential for various skin conditions, such as acne or dermatitis. The skin barrier, which serves as the first line of defense against environmental aggressors, can become weakened, making it more susceptible to irritants, allergens, and pathogens. This impaired barrier function can also hinder the skin's ability to retain moisture, leading to dryness and flakiness.

In contrast to the other choices, which suggest positive outcomes such as improved barrier function, decreased sensitivity, or enhanced product absorption, the reality is that over-exfoliation disrupts the balance of the skin, leading to negative consequences. Though some degree of exfoliation is beneficial for promoting cell turnover and a youthful appearance, moderation is key to maintaining skin health.
