The person from @[Image 2](image_2) must perform exactly the same movements and actions as the person in the original video, with realistic facial features, body proportions, skin texture, lighting, and motion. Replace the original skincare product with the exact product shown in @[Image 1](image_1). Preserve its exact packaging, shape, proportions, pump, label, colors, logo, typography, and visual identity. The product must interact naturally with the person’s hand and remain consistent throughout the entire video. Replace the original environment/background with the exact environment shown in @[Image 3](image_3). Integrate the person naturally into this location with matching perspective, lighting, reflections, shadows, depth of field, and color temperature.
