A clean, refreshing vertical advertising poster design for Arencia Vitamin C Booster, using a graphic illustration style with soft watercolor and vector elements. The poster is set against a clean white and light teal background. Do not show the model’s face; use a faceless, cropped figure or omit the person entirely, keeping the composition focused on the product. The overall style is clean, modern, and graphic, with flowing organic shapes, stylized leaves, flowers, and water splashes in shades of aqua, teal, light green, and white. The background features delicate, stylized botanical illustrations that complement the product. At the top, large, friendly, rounded sans-serif font reads in Arabic: "إشراقة تبدأ من العناية". Below it, a catchy Arabic tagline: "انتعاش، عناية، وإشراقة". The main product, a clearly recognizable Arencia Vitamin C Booster bottle, is illustrated prominently. Include Arabic product details and benefit claims only when verified from the official Arencia website; do not invent product claims or ingredients. Add small graphical icons around the bottle with concise Arabic labels based on verified official product information. Small illustrative bubbles, stars, and botanical accents float around the composition, adding a sense of lightness and freshness. At the bottom, include Arabic availability text, the Arencia logo, and social media details if provided. The poster has a clean layout with ample negative space and soft, natural lighting. Ensure all visible text is in accurate, legible Arabic.
