What is Acquired Sensitization?

Skin that was not originally sensitive but became so through excessive treatments or harsh ingredients

Caused by retinol or AHA overuse, excessive peeling, or incorrect skincare routines that damage the barrier.

Main causes & characteristics of Acquired Sensitization

This refers to a state in which skin that was not originally sensitive gradually becomes more reactive due to aggressive care habits. Overuse of retinol or AHAs, frequent peeling treatments, and incorrect skincare layering are reported to progressively weaken the stratum corneum and skin barrier, lowering the threshold for irritation responses. The condition tends to emerge once the cumulative burden on the skin exceeds a tipping point.

Managing Acquired Sensitization

It is generally recommended to reduce the frequency of active ingredient use and allow a recovery period focused on restoring the skin barrier. Moisturizing with a product that contains a balanced blend of ceramides, cholesterol, and fatty acids while identifying irritants one by one is advisable. If the condition does not improve, consulting a dermatologist is recommended.

This concept is frequently mentioned alongside reactive skin, impaired skin barrier, and management of stratum corneum exfoliation. It is also connected to the approach of reintroducing active ingredients at lower concentrations and gradually increasing them after recovery.

Everyday care tips

Rather than using exfoliating actives daily, it is better to start with once or twice a week and increase frequency gradually while monitoring your skin's response.
