My internal dryness is severe; will Vitaran be effective?

Lately, my skin has been so dry from within that it causes makeup to crack quickly and makes my complexion look dull, which is causing me a lot of stress. I am worried because moisturizing creams or face masks only provide temporary hydration before the skin dries out again quickly. So, I started looking into skin booster treatments and learned about Rejuran, but I hesitated after hearing that it is painful. Then, I became interested in a treatment called Vitaran because I heard it is much less painful and contains salmon DNA, which is good for skin regeneration.

 

What I am curious about is whether I can immediately feel an improvement in skin texture or hydration after just one Vitaran session. I would also like to know if consistent treatment is necessary to see results, and if post-procedure care is difficult. If there are any people struggling with internal dryness who have tried Vitaran, it would be really helpful if you could share what actual changes you experienced and how satisfied you were.
