How many Rejuran Healer treatments do I need to feel a noticeable improvement in inner dryness and skin texture?

Lately, my skin has been very dry from within, and it feels like the texture has become rough.

I am wondering if Rejuran Healer is effective for this type of skin.

I think one session might not be enough. Do I need to get it periodically?

Number of procedures Usually, after how many sessions did you feel the effects of internal dryness being resolved and your skin texture becoming smoother?

Treatment interval: I am wondering how many weeks it is best to space out the treatments between sessions.

Experience of skin changes It would be very helpful if you could share your experience regarding whether you actually received help with skin tightness or skin tone improvement after getting the injection.
