Use the provided white-background product image as the locked product reference. Keep the white DR.ALVA toner bottle unchanged: tall rounded bottle, white cap, cap lettering, DR.ALVA logo, Chinese/English label layout, pale blue graphics, proportions, and front-facing angle.
Create a vertical premium hydrating skincare poster in a cool blue-white laboratory water style. Use transparent glass test tubes with blue liquid and bubbles plus a shallow glass water basin, but change the number of tubes, tube angles, crossing pattern, water levels, bubble positions, and basin shape from the original.
Lighting: crisp cool studio light, glossy water highlights, transparent glass refractions.
Constraints: preserve product label/logo; no extra poster text outside the product label, no watermark, no border.
Avoid: copied test-tube arrangement, duplicated basin, distorted bottle, unreadable label, people, hands.
