Black Friday Crimson Serum Sale

Professional Black Friday e-commerce sale poster, vertical 9:16, glossy crimson cosmetic-serum promo with satin ribbons. [Colors] Background is a rich crimson-to-scarlet gradient lit from the upper right, with translucent red satin ribbons sweeping across the corners; the top headline is white with a red accent bar; offer pills are white and red; the two vials are clear glass with silver caps and red-banded labels; the bottom echo line is large semi-transparent white outline caps. No frame border. [Layout] A small logo row tops the frame; the two-line headline and red sub-pill fill the upper third with a small date line beneath; the two serum vials float centred at a slight tilt in the middle band, ribbons passing behind; the bottom sixth carries the giant echo headline bleeding off the left edge. [Subject] No people. Two clear glass serum vials with brushed silver aluminium caps, labelled in English "REGEN — Recombinant Type III Humanized Collagen Liquid Dressing, Spec: 45mg+3ml" on clean white-and-red labels; crisp specular highlights, floating at slightly different heights amid curling red satin ribbons and small red envelope accents. [Headline] Top in heavy white caps: "BLACK FRIDAY MEGA SALE". Red pill in white italic: "Beauty First! Price-Locked All Week". Small white date line: "Event: Nov 21, 00:00 - Nov 28, 23:59". Bottom echo in huge outline caps: "BLACK FRIDAY MEGA SALE". [Badges] Two small red envelope icons with $ marks float beside the vials as decorative accents. [Mood] Lush, festive and clinical-clean; deep crimson satin luxury keeping the sterile glass vials as the hero.
