What is Acquired Sensitization?

Skin that was not originally sensitive but became so through too many clinic sessions or harsh ingredients

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

Main causes & characteristics

This refers to a state in which skin that was not originally sensitive gradually becomes more reactive due to aggressive skincare habits. Overuse of retinol or AHAs, frequent peeling sessions, and improper product application order are reported to progressively weaken the stratum corneum and skin barrier, lowering the threshold for irritation. The condition tends to appear once cumulative stress exceeds a tipping point.

How to manage

It is generally recommended to reduce the frequency of active ingredient use and allow a rest period dedicated to barrier recovery. Moisturizing with a balanced formulation containing ceramides, cholesterol, and fatty acids while systematically identifying irritants one by one is advised. If the skin does not calm down, consulting a dermatologist is recommended.

Good to know alongside

This is frequently mentioned alongside reactive skin, skin barrier damage, and stratum corneum exfoliation management. It also connects to the concept of gradually reintroducing actives at lower concentrations after recovery.

Everyday care tips

Rather than using exfoliating ingredients daily, it is better to start at one to two times per week and increase gradually based on how your skin responds.
