Three Beauty Mobile Landing Pages

A sophisticated promotional mockup showcases three elongated smartphone screens side-by-side in a vertical triptych layout, each displaying a landing page for a modern beauty brand's lip products. The overall composition is editorial, minimalist, and sophisticated, designed specifically for mobile web design presentations on social media. The left panel, set against a soft gradient background from pale purple to blush pink, displays a black-bezeled phone with a screen featuring {argument name="brand name" default="Kosas"} A beauty website featuring cream-toned blushes. At the top of the panel, elegant small serif fonts read {argument name="left headline" default="Fresh Pout."} The top of the phone screen displays a cropped close-up image of a beauty product, with the prominent headline "Lips in their fullest expression." (The word "fullest" is in italic serif style), accompanied by a rounded, dark call-to-action button, a row of three lip close-up thumbnails, three effect labels labeled "Plumps," "Tingles," and "Shines," and a row of five shade or effect icons below. The middle panel, set against a gradient background from light to dark purple, showcases a second phone with a black bezel, whose landing page has a more sophisticated layout. The serif font above reads {argument name="middle headline" default="Claude Code"} The top of the screen features a cropped portrait image, a striking black stacked headline "LIP PULSE.", below which is a line of pink italicized handwritten text "is here.", a rounded dark button, a dark area containing the phrase "Lips in their fullest expression.", and a product grid near the bottom containing six color code cards (arranged in 2 rows and 3 columns). The right panel, set against a deep navy blue textured background, showcases a third phone with a black bezel, its page featuring a pink-toned e-commerce style. At the top center, in uniform white font, is the text {argument name="right headline" default="GPT Images 2.0"} The screen prominently displays the product's homepage area, featuring the brand name "Kosas," the large headline "The Lip Pulse," a pink lip gloss tube tilted to the right, small function icons, a row of six lip swatches near the center, and a promotional section below with images of more pink products. Maintaining a symmetrical layout, exactly three phones are positioned vertically, one on each panel, all fully visible. It employs high-end cosmetics advertising aesthetics, clean spacing, a stylish web typography with a mix of serif and bold sans-serif fonts, a soft pink and cream UI color scheme, subtle shadows, and a fashionable product design suitable for showcasing an AI-generated mobile website concept.
