What are the signs of over-exfoliation?

Over-exfoliation refers to the excessive removal of dead skin cells, which can lead to various harmful skin reactions. The signs of over-exfoliation typically include redness, irritation, and peeling skin. These symptoms occur because the skin barrier is compromised, making it more susceptible to irritation from environmental factors and products. When the outer layer of the skin is stripped too frequently or too aggressively, the underlying layers become exposed and can easily become inflamed or reactive.

In contrast, enhanced glow and radiance, which may initially seem appealing, are not typical signs of over-exfoliation. Such a condition would generally indicate a healthy skin glow from proper exfoliation, not from excessive treatment. Increased oil production can also occur due to a disrupted skin barrier, but it isn't a definitive sign of over-exfoliation on its own. Decreased sensitivity is misleading as well; typically, over-exfoliation increases skin sensitivity, making the skin more reactive and prone to discomfort due to the loss of its protective barrier.
