What it is
This is a quasi-drug cushion foundation that focuses on wrinkles, blemishes, and rough skin. With SPF50+, PA++++, and UV water resistance test★★, the environment surrounding our skin—UV rays, sweat, dryness, etc.—is becoming increasingly harsh year after year. This Barrier Makeup®-inspired cushion foundation was created with the desire to protect skin from such external stressors all day long. The active ingredient niacinamide approaches wrinkle improvement and whitening*1, while the active ingredient dipotassium glycyrrhizate prevents rough skin and dryness damage, keeping skin healthy. It also contains a light-feeling polymer*2 that is lightweight and highly adhesive, and a lasting polymer*3 that enhances makeup longevity. It fits even the active skin of adults, preventing creasing and shine while maintaining a beautiful finish for a long time. Furthermore, the light-feeling polymer*4 with a soft-focus effect gently covers skin concerns such as blemishes, pores, and dullness. It provides excellent coverage for problem areas without feeling heavy, creating a translucent, natural-looking glow that makes your skin appear naturally beautiful. Formulated with five moisturizing ingredients*5 and five plant extracts*6 for mature skin prone to dryness, it provides moisture and firmness, and the skincare effects continue while you wear it. The included teardrop-shaped puff fits easily into small areas such as the sides of the nose, corners of the mouth, and around the eyes, ensuring a smooth and beautiful finish. It is also easy to use over Kazuki and design tapes, supporting an even smoother finish.

How to use
First, remove the protective film from the mirror before use. Use after washing your face and preparing your skin with lotion and emulsion. (1) Place 2-3 fingers on the included puff and gently press it onto the cushion surface 2-3 times to pick up an appropriate amount. (2) Gently pat the product onto your face and spread it evenly. If the puff becomes dirty, dissolve a small amount of mild detergent in lukewarm water, gently wash it by pressing, rinse thoroughly, remove excess water with a towel, and air dry in the shade.
