I would like to get Quadsay to refine my hair texture. What is the procedure like?

My skin's oil-moisture balance has been completely disrupted due to the office heating and cooling, so I am seriously considering Quadsay Care, a gentle treatment. I looked into stopping by on my way home from work, and I heard that because it uses a non-irritating ultrasound method, you can return to your daily routine immediately without any side effects or downtime.

However, since this isn't a treatment that ends after just one or two sessions, I'm asking those who have actually received Quadsay. How much redness or skin irritation is there immediately after the procedure? I'm wondering if it will be okay to apply makeup or go to work the very next day. Compared to standard aesthetic hydration treatments, are the effects of Quadsay—such as deep hydration and texture refinement—clearly noticeable? Please advise on how many sessions I should purchase in a package to see proper skin barrier improvement.
