It has a pattern.\n\nSkinsign is the first skin coach that connects your lifestyle to your breakouts. Scan your face, scan your food, log how you sleep and how stressed you feel. See exactly which triggers are showing up on your skin.\n\nWHY SKINSIGN IS DIFFERENT\n\nMost skin apps recommend more products. Skinsign does the opposite. We help you see how your habits show up in your skin, so you can change what's working against you. Built by someone who spent years fighting acne with every product on the shelf, only to clear his skin by figuring out his own triggers. Skinsign is the tool he wishes he had.\n\nHOW IT WORKS\n\n1. SCAN YOUR SKIN\n\nTake a quick face scan. Get four clear scores: acne, redness, texture, hydration. No vague ratings. No vanity metrics.\n\n2. SCAN YOUR FOOD\n\nPoint your camera at any barcode. Skinsign reads the ingredients, scores the product for your skin, and flags what could be triggering you: added sugar, dairy, seed oils and more. No barcode? Snap the ingredient label instead.\n\n3. LOG\n\nTrack the four things that actually move your skin: food, sleep, stress, water. Thirty seconds a day.\n\n4. DISCOVER\n\nOur Correlation Engine finds patterns you'd never spot on your own. See which habits line up with your clearest days and which show up on the rough ones. The more you log, the more you'll notice.\n\n5. UNDERSTAND\n\nRead quick, jargon-free articles on what actually affects your skin. Nutrition. Hormones. Sleep. Stress. No influencer opinions. No product pushing.\n\nWHAT YOU GET\n\n- Face scans with four skin scores\n\n- Daily log for food, sleep, stress, hydration\n\n- Food scanner that scores any barcode and flags your likely triggers\n\n- Personal trigger insights from your own data\n\n- Progress tracking with side-by-side before and afters\n\n- A library of short articles, grounded in science\n\n- A streak system that rewards consistency, not perfection\n\nWHO SKINSIGN IS FOR\n\nIf you've tried every serum, every routine, every product, and your skin still won't cooperate, you're probably chasing the symptom and missing the pattern. Skinsign helps you see it.\n\nBest for people between 16 and 30 who want to understand their skin instead of just covering it up.\n\nPRIVACY\n\nYour face scans and logs stay private. We don't sell your data. Ever.\n\nStart your first scan. See what your skin has been trying to tell you.\n\nIMPORTANT\n\nSkinsign is a health & wellness tracking tool. It is not a medical device. It does not diagnose, treat, or cure any medical condition, including acne. Always seek a doctor's advice in addition to using this app and before making any medical decisions regarding your skin.\n\nTerms of Use: https://skinsign.app/terms","facts":{"developer_id":1892848552,"developer_url":"https://skinsign.app/","first_released":"2026-04-24T07:00:00Z","support_url":"https://skinsign.app/","privacy_url":"https://skinsign.app/privacy","website_url":"https://skinsign.app/","app_version":"1.3.12","release_notes":"You can now see every product you have scanned and you can go back and log days you have missed.","rating_current_version":4.64516,"rating_count_current_version":217,"star_counts":[1,3,13,38,162],"genres":["Health & Fitness","Lifestyle"],"languages":["EN"],"content_advisories":["Infrequent/Mild Medical/Treatment Information"],"device_families":["iphone","ipod"],"made_for_iphone_duo":false,"chart":null},"freshness":{"apple_read_at":"2026-11-11T22:05:13.384Z","catalog_read_at":"2026-11-13T20:37:13.087Z","reviews_checked_at":null,"summary_written_at":"2026-11-12T10:32:13.062Z","placed_at":"2026-11-11T22:27:12.906Z","scored_at":"2026-11-14T07:25:13.195Z"},"editorial":{"one_liner":"Tracks face scans, food barcodes, sleep, stress and water to show which habits line up with acne breakouts.","what_is":"Skinsign is a health and fitness app that scores face scans for acne, redness, texture and hydration.
