Livihill Recommended Frequency and Frequency

Hello. Recently, perhaps due to the change of seasons, my skin has become noticeably rough and severely dry from within, so I am considering the Liviheal treatment.

My skin is a bit sensitive and tends to get red frequently, and I heard that Libby Hill is good for skin regeneration. Typically, for a skin type like mine, how many sessions would be needed to restore my condition? I am also curious whether a 2-week or 4-week interval between treatments would be better. I look forward to your reply!
