美白提亮面膜 (Whitening & Brightening Mask) [00-04s] Ingredient Purity & Texture: A cinematic macro shot of a single, unfolded white silk mask sheet floating in mid-air against a pure white background. A clear, viscous essence drips onto the sheet in slow motion. The essence is filled with glowing gold micro-particles (representing Niacinamide). As the drop hits the mask, it absorbs instantly, making the sheet translucent and heavy with hydration. [05-08s] Perfect Fit & Absorption: Cut to a model applying the mask to her face. The camera focuses on the nose and eye areas, showing the custom cut that fits perfectly without air bubbles. A special visual effect shows the glowing essence penetrating deep into the skin layers (cross-section view of epidermis). Dark melanin spots in the deep skin layers visually fade away as the light touches them. [09-12s] The Reveal: The model peels off the mask slowly. Her skin underneath is visibly brighter (1.5 shades lighter), dewy, and plump with moisture ("Glass Skin" effect). [13-15s] Elasticity Check: She gently presses her cheek with a finger, and the skin bounces back elastically with a watery glow highlight on the cheekbone.
