Mouthwash Flash Sale Product Image

[Format] Professional e-commerce product main image, square 1:1, high-energy red-orange flash-sale style with glowing bokeh light. [Colors] Vivid red-to-pink gradient background from #e8262f into #ff7a4f with soft circular bokeh spots, turquoise product liquid, a purple coupon block, white badge panels; no frame border. [Layout] The text stack fills the upper-left; the large bottle stands right of centre with a filled glass in front of it; a coupon ticket and a price badge stack down the lower left, keeping the right side clear for the product. [Subject] Right: a large faceted bottle of bright turquoise mouthwash with a clear screw cap, glossy highlights running down its ribbed sides, beside a short clear glass half filled with the same blue-green liquid. [Headline] Upper left in white: "Bestseller Pick" on a small tag, then "Imported Original" in large outlined bold, then a pill reading "The Rinse Alternative"; a purple coupon ticket shows "$20 Off" with "Clip Coupon For Instant Savings" beneath; the lower-left white badge with soft cat-ear curves reads "Final Price" above "$29.9" in enormous red numerals with a small "$" prefix. [Mood] Flashy deal-driven excitement; hot red ground, icy turquoise product, giant price numerals pulling the eye to the bottom left.
