What kind of care should I take to restore the skin barrier?

Hello~ I would like to inquire about skin barrier recovery management.

My skin has become a lot rougher these days and even though I exfoliate,

When I put on makeup, the area around my cheeks gets really flaky, maybe because of the dead skin cells?

I wonder if this is because the skin barrier is damaged a lot.

Is it possible that exfoliating too much can destroy the skin barrier?

Is it really possible to restore the skin barrier? What kind of treatment is needed to restore it?

Is it possible to restore the skin barrier through skin care or laser treatment?
