Would you like to share my all-time favorite skin barrier care product that I suddenly became curious about tonight?

Sigh, is everyone asleep? It's already 11 PM... Actually, on my way home from work today, I had a bit of an argument with my best friend over something trivial, so I've been feeling down and haven't been able to fall asleep... ㅠㅠ You all know that feeling of lying in bed with a nagging ache in the back of your mind, right? On top of that, I don't know why I'm so unlucky today, but I spilled a whole bunch of coffee on my favorite shirt at lunch, so my mood was completely ruined. It's so cold outside, and I've had the heater on all day, so my face feels like it's going to crack. So, I put on a sheet mask to soothe myself, but it suddenly occurred to me that the skin barrier care product I'm currently using might not be the best. The one I've been using lately is packed with ceramide, but no matter how much I apply, it's no match for the winter wind... Do you guys have any skin barrier care products you've settled on and would recommend? I was wondering if there are any angel members out there who can be a savior for someone like me with extremely dry skin that goes crazy every winter! Especially at times like this, using just one proper skin barrier product can really boost your skin condition. I know it might be a hassle late at night, but could you please share just one secret product you're currently using? My skin texture feels really damaged, and I'm so upset tonight that I really need your help...! Please take care of your health and get those beautiful, glowing skin days!
