Roughly how often should I use Celre Diem to soothe facial redness and heat? ㅠㅠ

Even the slightest heat makes my face instantly flush and turn bright red like a burning sweet potato ㅠㅠ When I get hit by the air conditioner, it feels so dry it feels like it's going to crack, and it feels like my skin barrier has completely collapsed, so I just sigh every time I look in the mirror lol. This is said to be the best for cooling, soothing, and strengthening the barrier. Seldiem I was recommended this, and is it really super effective for calming redness? I don't think one session will be enough; usually, it takes a few weeks. to give I'm wondering if I need to get treatments regularly tailored to my skin to make it feel comfortable lol. For someone like me with extremely sensitive and thin skin Seldiem I'm curious if it really fills in the inner glow when hit ㅠㅠ I'm trying to build a strong barrier. Seldiem Those of you who have gotten this, please leave lots of great aftercare tips lol
