Build this as a scalable MVP with future startup potential, focusing on Indian beauty consumers.
I'll build this premium skincare comparison platform as a scalable MVP with a luxe aesthetic. This is a complex multi-system application, so let me structure it properly.
Now let me start building the application. I'll begin with the database schema and seed data.
Now I'll start building the platform. Let me create the database schema, types, and seed data first.
I've set up the complete database schema with tables for products, prices, users, routines, alerts, and ingredient conflicts. The schema includes comprehensive seed data with real skincare products across different price ranges and platforms. Next, I'll build the AI Skin Quiz and personalization engine.
Let me continue building the platform systematically. I'll move to the next task.
Now let me build the AI Skin Quiz and personalization engine with API routes and components.
I've built the AI-powered skin quiz with personalized analysis using the LLM. The quiz collects user data across 5 steps, sends it to the AI for analysis, and displays detailed recommendations with ingredient guidance and routine structure. Now let me move to building the price comparison system.
I've created a comprehensive price comparison system with intelligent deal scoring that considers price, discounts, free gifts, delivery speed, and stock availability. The system includes a "Build-Your-Bag" optimizer and visual components for comparing prices across platforms. Let me continue with the routine builder and ingredient checker.
I've built a comprehensive routine builder with real-time ingredient conflict detection, safe layering order, and cost calculation across routines. The system checks for common incompatibilities like retinol+vitamin C and uses AI for additional analysis. Now let me build the user dashboard and product pages.
I've created the main pages including a luxe-styled homepage with hero section, features, and product grid, plus a detailed product page with tabs for comprehensive information. The design uses elegant neutrals with rose gold accents for a premium beauty aesthetic. Now let me complete the final task with alerts and saved features.
Perfect! I've completed all the tasks and built a comprehensive premium skincare comparison platform. The application now includes saved products management, price alerts with target notifications, and a complete dashboard for users to manage everything. Let me mark the project as complete.
I've successfully built a production-ready premium skincare comparison platform tailored for the Indian beauty market. Here's what has been delivered:

Now I'll update the branding to "DERMY" and add makeup product recommendations throughout the app.
Now I'll make the changes to rebrand to DERMY and add makeup recommendation functionality throughout the platform.
I've successfully rebranded the platform to "DERMY" and integrated makeup product recommendations throughout the application. The changes include updated branding in the header, footer, page titles, and meta descriptions. The AI analysis system now recommends both skincare and makeup products based on user's skin profile, climate, and concerns. The recommendation API separates skincare and makeup products while maintaining compatibility with existing components.
