No matter how much skincare I apply, my inner dryness is insane. Would Rivicol be okay? ㅠㅠ

My skin feels incredibly tight deep down, whether it's because of the weather lately or sitting under the air conditioner all day. Even after slathering on hydrating ampoules and heavy moisturizers morning and evening, the feeling of my skin cracking deep inside just won't go away. My cheeks look dry and cakey whenever I apply makeup, and when I go barefaced, my face feels like it's going to tear apart. I'm seriously so stressed out I could die. I don't think I can overcome this with home care alone, so I'm looking into skin booster treatments at a dermatology clinic. I heard that the Revicol injection, which replenishes collagen, is really famous for tackling inner dryness. I'm wondering if my typical combination skin—super sensitive, oily on the outside but dead on the inside—can still achieve that hydrated, glowing inner skin that looks like a peeled egg. I'm also curious if there is any pain, if the marks don't last long, and if I can return to my daily life immediately after the injection. Please, those of you who have tried it, leave some really honest advice!
