My face feels really tight and dull. Roughly how much does Quad Say cost? ㅠㅠ

After returning from summer vacation, perhaps because I was exposed to too much air conditioning, my skin has completely cracked like a desert, and the inner dryness is seriously no joke ㅠㅠ No matter how much moisturizer and face mask I apply before bed, my face feels like it's going to tear apart by morning, and when I put on makeup, it just sits on the surface around my nose, so I'm so stressed lol. To firmly tackle inner dryness and strengthen the skin barrier, I need something that replenishes moisture. Quadsay I was recommended this because it's super popular these days! Even for sensitive, dehydrated combination skin like mine—oily on the surface but extremely tight underneath—will it give a dewy, inner glow? I've heard that people usually sign up for a 3-session package at dermatology clinics. Quadsay Approximate price I'm so curious about the estimate. I'm scared of the pain, but I wonder if it will be painful. Quadsay Those of you who have been hit, please give me some vivid advice lol
