With the change of seasons, my skin is flaking and my internal dryness is severe. What kind of treatment would be best?

As soon as the change of seasons arrives like this, my skin senses it first; dead skin cells are flaking off in white patches, and the dryness deep inside is so severe that I think I need to get a treatment.

Even though I apply a thick layer of moisturizer frequently, it doesn't absorb deep into my skin and just sits on the surface, causing my makeup to cake and look messy. I am wondering what the most effective treatment is at Maypure for hydration or skin barrier care specifically for the changing seasons.

Please let me know if a moisturizing scaling treatment like Aqua Peel is better, or if it is faster to use a skin booster to directly address internal dryness!
