BIAS SKIN: AI Skin Coach

BIAS SKIN is the AI K-beauty coach that reads your skin like a Korean cosmetic scientist would. Calm, observational, no pressure. Your skin has a bias. Its favourite tone, texture, and rhythm. Find yours in a quick skin-type quiz, then track it over 8 weeks with AI photo skin analysis, an ingredient label scanner, and a 30-day routine curriculum. Built for K-beauty readers who want substance over noise. No ten-step minimum, no celebrity name-drops, no urgency tricks. [ What's in BIAS SKIN ] - Skin-Type Bias Quiz Find your K-beauty "bias", one of six skin types (Dewy Glass, Sensitive Porcelain, Oily Combination, Dry Velvet, Mature Radiance, Acne-Prone Clear). About 30 seconds. No medical advice. - AI Photo Skin Analysis (Pro) Take a guided self-portrait. Claude Vision returns 5 descriptive signals (hydration, clarity, texture, pores, redness) on a 0-100 scale plus a per-region map. Cosmetic observation only, never a diagnosis. - Ingredient Scanner (Pro) Shoot the back of any K-beauty product. We read the INCI list, score fit for your bias, flag potential irritants, and call out vegan and halal compatibility automatically. - 8-Week Timeline Weekly-averaged trend chart for all 5 skin signals. Compare any two scans side-by-side with a drag slider. Pro adds Claude-written trend insights. - 30-Day Challenge A gentle K-beauty curriculum with five phases (Reset, Hydrate, Brighten, Refine, Maintain). One small action a day. The first 7 days are free; Pro unlocks the full path. - Shared Shelves Build your own bias edit. Browse public shelves (Glass Skin Routine, Sensitive Skin SOS, Halal-Friendly Picks). Trade share codes with friends. - Quiet Reminders Daily challenge nudge, AM/PM routine, 24-hour streak care, all opt-in. Local notifications only, no surprise push. [ Why K-beauty readers choose us ] 1. Four languages, native voice English, Korean, Spanish, Arabic. Each translation is naturalised by Claude, no robotic feel. Arabic is right-to-left with a warm older-sister tone. 2. Halal and vegan flags, auto Mention snail mucin in an Arabic-language scan and you get an inline "not suitable for halal routines" note, automatically. No guessing INCI lists in three languages. 3. Soft phrasing only Korean cosmetic scientist meets warm older sister. Never "you have acne", always "skin shows congestion in this area." Never "prescribed", always "may help support."
