Handheld, selfie-style front camera in a real bathroom. Soft daylight from a window; slight phone shake is okay. The young woman (natural skin texture, minimal makeup) leans toward the lens in a striped or simple tee, hair casually pulled back. Background is real-life bathroom—white tiles, mirror smudges, a plant slightly out of focus. She brings a brown glass serum bottle with black dropper up close to the camera so the label fills frame, then pulls it back to her face. Framing notes: start tight on her face/hand, brief focus rack to the bottle, then back to her eyes. Keep cuts minimal (one continuous take preferred).
