A close-up 3D shot focuses on a sleek glass dropper held above a pristine glass serum bottle. A single droplet of serum forms at the tip, catching the soft, diffused lighting and reflecting subtle highlights, emphasizing the liquid’s smooth, viscous texture. The drop slowly elongates and detaches, suspended mid-air for a moment before falling into the bottle below, creating a tiny ripple on the serum’s surface. The background is minimalistic, softly blurred to keep the focus on the dropper and the liquid, highlighting the elegance, purity, and premium quality of the serum. The materials are realistic—glass reflects light naturally, the liquid has slight translucency, and the dropper has a subtle metallic or rubber tip finish.
