Cinematic web experiences for premium brands

Cinematic web experiences for premium brands

Same brand. Different world. Took HandSkill's website from outdated to premium — without changing who they are. The old site had the right ingredients: strong brand colors, real product photography, clear navigation. But it felt stuck in 2015. No hierarchy, no conversion focus, no visual confidence. The redesign kept the identity and elevated everything else: → Editorial hero layout with product staging → Typography that commands attention → Social proof bar above the fold → Clear CTA that actually converts Built with HTML, CSS, and AI-assisted design — delivered fast, without sacrificing craft. Before → After. Swipe. What do you think — which element made the biggest difference, the typography or the product staging?" #webdesign #redesign #brandidentity #beforeandafter #landingpage #uidesign #cosmetics
