I'm a working professional suffering from internal dryness like crazy ㅠㅠ Is this the correct characteristic of Vitaran?

Hi haha. I'm a 5-year veteran IT planner battling the heat from my monitor every day. The office is so dry that even though I empty a bottle of mist a day, I was suffering from internal dryness that felt like my face was going to crack by the afternoon. ㅠㅠ I have combination skin—oily on the surface but parched underneath—so no matter how thickly I applied moisturizer, it wouldn't absorb and just sat on the surface. So, I squeezed in some time during my lunch break to search extensively for skin boosters, and I'm getting really interested in Vitaran because there are so many reviews saying it's a surefire way to replenish moisture! ㅋㅋ

Since there are so many types of skin boosters, I'm getting confused. Is it true that Vita strengthens the skin barrier and locks in deep hydration? I'm also really curious about how it compares to other boosters in terms of bumps or pain. I'm a total scaredy-cat who is terrified of needles, so I'm hesitating to pay yet because I'm afraid I might run out of the room during the procedure due to the pain.

If any of you seniors in the community have tried Vitaran, please share some real stories about its characteristics. Is it painful enough to bring tears to your eyes, or is it bearable if you apply anesthetic cream? I'm also curious how many times I need to get it at one-month intervals to have skin that doesn't feel tight after washing my face.

I've decided to bite the bullet and go on a dermatology clinic tour this weekend. I would be so grateful if you could share any tips on choosing a clinic that administers Vitaran thoroughly. This year, I really want to escape this persistent inner dryness and transform into having firm, supple skin that prevents makeup from caking. Haha. Everyone, please make sure to moisturize your skin regularly!
