What is the standard recommended number of Density High sessions for sensitive skin?

Nice to meet you. My skin barrier is very thin and sensitive, so I have a skin type prone to severe redness that breaks out and becomes extremely dry if I receive irritating treatments. As an alternative, I was recommended high-frequency skincare that precisely regulates thermal energy, but I am concerned about the number of sessions. For someone with skin like mine, which is very weak and severely saggy, I would like to know if the recommended number of consecutive Density High sessions is the standard approach. I have heard that you need to periodically apply the tip once or twice a year to send energy and allow regeneration to occur from within, thereby strengthening the barrier; however, I am worried about whether this will really be too much. I am curious to know exactly how many Density High sessions are required to feel the barrier regeneration effects. I am seeking warm advice from those with similar skin types who have had success with this product. Please let me know the effective frequency and application cycle for Density High.
