A vertical split-screen advertising poster, clean minimalist commercial photography style. LEFT HALF: cool muted grey-green background (#8E938E). A dark amber glass skincare serum dropper bottle with a matte silver collar and a dark rubber pipette top, sitting upright, soft studio lighting, subtle shadow. The bottle label is deliberately blurred and partly censored with a small black redaction bar, suggesting hidden ingredients — mysterious, secretive mood. RIGHT HALF: deep clean forest-green background (#10513C). A frosted clear-glass serum dropper bottle with a silver collar , standing upright, bright even lighting. It has a crisp, highly readable white minimalist label printed with a clear ingredient list. A subtle magnifying-glass icon hovers near the label, implying "look closer" — honest, clinical, trustworthy mood. TEXT (large bold white sans-serif, all English, centered across the top): headline reading "WE PUT THE INGREDIENTS ON THE FRONT" with a smaller tagline underneath: "Ingredients you can actually read." Bottom left: large price "$80" with the words "LEGACY BRAND" below. Bottom right: large price "$28" with the brand name "MÍNGBAI" below. Flat, modern DTC beauty-brand aesthetic, no gradients, no clutter, high contrast between the two halves. Premium editorial product photography. All text in English only.
