Lately, even though I apply plenty of moisturizer, it feels like my inner dryness has gotten much worse. My skin feels rough and flaky to begin with, and it's really stressing me out that my makeup cakes. I'm thinking of getting some kind of skin booster treatment. How effective is Rejuran for severe inner dryness?

I saw it on YouTube and it looked promising, so I'm thinking of visiting a nearby dermatology clinic in Wonju for a consultation. Do you happen to know of any places where you had good results?
