极简风止痒膏海报

A clean minimalist vertical product poster on a soft pale gray background with a subtle green tint, designed like a modern Chinese skincare or medicine advertisement. Show a {argument name="character type" default="Charlie Chaplin lookalike"} from the chest up on the left side, wearing a black bowler hat, black suit jacket, white shirt, dark tie, and gray vest, posed formally and holding a bright green plastic jar of {argument name="product name" default="anti-itch cream"} with a white lid in both hands at center-left. One hand supports the jar from below while the other points toward it, creating a clear product presentation pose. The face should have a gentle pleasant expression, but keep the composition focused more on wardrobe, hands, and product than facial detail. On the upper right, place a green brand logo and Chinese brand text. Below it, add large elegant green Chinese headline text reading “舒缓 止痒膏” and smaller English subtitle text “ANTI-ITCH CREAM”. To the right of the jar, include a circular botanical graphic with {argument name="herb" default="mint leaves"}, plus exactly 2 green checklist claims in Chinese beneath it. At the bottom, add a curved white panel spanning the width of the poster containing exactly 3 evenly spaced green line icons with Chinese captions: a leaf icon for cooling itch relief, a water droplet icon for moisturizing dry itch, and a shield icon for gentle protection. The product jar label should be yellow-green with Chinese text and small herb illustrations, matching the green branding. Overall style: sparse, neat, commercial poster, lots of negative space, premium pharmacy-ad aesthetic, soft studio lighting, realistic photography mixed with clean graphic layout, green-and-white color palette.
