I want to get Vitaran because of internal dryness. Does it really make my skin moisturized? ㅠㅠ

No matter how much moisturizer I apply, my skin feels really parched from the inside, so I'm thinking of getting some dermatological treatments. I can't bring myself to try the other famous procedures because of the pain, so I'm currently looking for reviews mainly for Vitaran, which is said to be less painful.

If the results are guaranteed, I want to pay for it right away. I'm really curious if getting Vitaran injections actually brightens the complexion and completely resolves internal dryness. It's quite expensive, isn't it? I'm worried it might not work, so I really need some advice.

I want to get Vitaran because of internal dryness. Does it really make the skin moisturized? If anyone has tried Vitaran themselves, I would be so grateful if you could share your honest, genuine review of how many sessions it took to feel the effects!
