I'm trying to tackle internal dryness before winter comes, so I'm curious about the skin booster treatment cycle and how to use a soothing cream.

Ever since temperatures dropped sharply in the mornings and evenings, white flakes of dead skin have been appearing on my cheeks after washing my face. No matter how many layers of toner I apply, my skin feels tight immediately; applying a thick layer of cream helps a little, but the tightness returns, and this cycle repeats. I would like to ask a few questions because I want to replenish moisture in advance with a skin booster before my skin becomes too dry to survive the winter.
1) How often are skin boosters typically used? I heard that you start with a few sessions at 2-week intervals, and then the intervals lengthen for maintenance; I'm curious if there is a significant individual variation.
2) How do you handle home care after the procedure? I am wondering if I can continue using my usual soothing cream, or if I should only use less irritating products immediately after the procedure.
3) I would appreciate it if you could let me know if there are any things to avoid before or after the procedure (such as drinking alcohol, saunas, or exfoliation).
Since my skin is on the sensitive side, I'm a little worried that the redness might last a long time after the procedure. It would be really helpful if you could share your experiences or tips!
