Studio beauty product photograph of a frosted-glass skincare serum bottle with a matte black dropper cap and a minimalist cream label reading 'LUMÉRA', 30ml, standing on a wet polished travertine slab. Single large softbox key from upper left, soft graduated warm-beige seamless background, gentle rim light separating the glass, a few fresh dew droplets on the shoulder of the bottle, a soft reflection pooling beneath. 100mm macro, f/8, dead-on eye-level hero angle, centered with generous negative space above. Luxury editorial cosmetics grade, creamy highlights, ultra detailed, photorealistic. No text on background, no watermark, no hands.

Minimalist luxury skincare label on cream stock. Largest, centered serif wordmark: 'LUMÉRA'. Below in small tracked-out caps: 'RADIANCE FACIAL SERUM'. Bottom line, smallest: 'Vitamin C + Squalane 30ml'. A thin gold hairline rule between wordmark and subtitle. Elegant, lots of whitespace, embossed-foil feel, high legibility.
