We mapped the full end-to-end journey, from unboxing to long-term treatment tracking, before a single screen was designed. The flow handles language selection, gender personalization, account creation, and device pairing via barcode scan, then guides users through a skin tone safety check and spot test before their first session. Treatment reminders, area selection across seven body zones, real-time session tracking, and a monthly progress calendar all live within a single, unbroken journey. Nothing is left to chance, because when you're dealing with a laser device, every edge case needs a designed answer.
