Recommended number of Vitaran treatments!?

Hello!! I have always suffered from internal skin dryness, but the loss of elasticity has become so severe that I am considering a skin booster treatment. While researching, I learned about the Vitaran treatment and heard that it is relatively painless and the effects last a long time! I looked it up and found that it is generally recommended to receive Vitaran treatments every 3 to 4 weeks!! I am curious about the specific recommended number of sessions! Does the recommended frequency remain similar even if skin thickness varies from person to person? My skin barrier is severely compromised, and I have very thin skin, so I am very worried about whether it is safe for me to follow the recommended number of Vitaran sessions as is typical for others!
