A luxurious glass serum bottle stands at the center of the frame on a reflective surface, softly illuminated by golden and white studio lights. From above, a single droplet of rich, glowing serum slowly detaches from a glass dropper. The camera focuses tightly on the droplet as it stretches with surface tension, refracting light like a jewel before releasing. In slow motion, the droplet falls gracefully into the open bottle, creating a subtle ripple and glisten inside the liquid. Tiny spark-like highlights shimmer across the droplet, giving it a premium, almost magical quality. The background remains minimal and blurred, ensuring the entire spotlight is on the elegance of the drop and the serum bottle.
