I have an inquiry about skincare.

My skin condition has been really erratic lately, so I really need some skincare tips. It's usually fine, but then it suddenly turns red or feels tight, making it difficult to manage.

I am curious about the most important skincare point among all the tips, especially during sensitive times like these. Are there any specific points I should pay particular attention to regarding cleansing methods or the order of my skincare routine? I would also like to know how to avoid overdoing these tips. Please let me know.
