Please recommend a treatment for facial flushing, heat sensation, and skin barrier strengthening.

It is truly distressing because my skin turns red constantly due to the high summer temperatures and UV rays. Even a short walk outside makes my cheeks flush red like carrots, and the temperature difference between indoors and outdoors causes my face to burn and even itch. It feels like my skin barrier has completely collapsed; it reacts sensitively to even the slightest external stimuli and does not calm down easily. Even applying a cooling soothing pack only cools the heat for a moment, and the slightest irritation causes it to flare up red again as if on fire. It is extremely stressful because the flushing is difficult to cover up even with makeup. Are there any treatments or skincare programs that can reduce the heat and strengthen the weakened barrier of this easily heated and sensitive skin?
