Restore the skin’s protective barrier and prepare the canvas.Just as a house needs prepared ground, the skin requires a clean, pH-balanced environment to function. This step focuses on removing impurities that block absorption while respecting the skin's acid mantle.

Balance lipid and moisture supply and stimulate renewal.This step acts as the solid foundation. Without it, the "walls" (collagen) will collapse because they cannot penetrate effectively. This involves exfoliation to remove the "glue" holding dead skin cells together.

Strengthen the skin structure for firming and lifting.The "walls" of the skin are built from collagen and elastin. Since natural collagen levels decrease with age, this step focuses on infiltrating skin-identical substances into the deeper layers to regain firmness and hydration.

Protection and reduction of specific concerns (wrinkles, hyperpigmentation).The final step is the "roof" that protects the interior. This includes sealing in moisture and targeting specific issues like pigmentation or deep wrinkles.
