My skin feels very dry deep inside due to the air conditioning in the middle of summer. Please recommend a treatment.

The weather has been so sweltering lately that I've been blasting the air conditioner all day long, both at the office and at home. However, constantly being exposed to the cold air has left the surface of my skin shiny with sweat and oil, while the inside feels severely dry, cracked, and tight, as if it were on a parched drought. Even applying generous amounts of moisturizer frequently at home feels like it just sits on the surface; perhaps due to the large temperature difference between indoors and outdoors, I've even developed redness on my face, and it feels like my skin barrier has completely collapsed. I am planning to get professional care at Maypure before it's too late. I am writing this post because I am curious about which treatment would be most effective for the extreme inner dryness and oil-moisture imbalance caused by summer air conditioning like mine. I would appreciate your advice and treatment recommendations on whether LDM Waterdrop Lifting, which replenishes moisture without irritation, would be better, or if it would be more appropriate to use a skin booster like Vitalan, which contains salmon extract, to promote inner regeneration.
