About

SkinStack AI

Your skin goals. One system that works toward them. SkinStack isn't just a product scanner. It's a skin-goals system that learns you, and everything in it feeds the same picture of your skin. Start with what you want to work on: dehydration, fine lines, dark circles, dark spots or pores. That becomes your goal, and everything else in SkinStack works towards it. SCAN. Scan a product's barcode, or photograph its ingredient list, and SkinStack reads it against your actual skin: your type, concerns and sensitivities, not a generic average. If a barcode isn't in our database yet, photograph the ingredients once and it's remembered for next time. INGREDIENTS TO AVOID. Choose what your skin doesn't get on with, such as fragrance, drying alcohols, sulfates, parabens, essential oils or silicones, or add your own. SkinStack flags them on every scan and every product on your shelf. FACE SCAN. About once a week, a selfie gives a cosmetic AI read of five areas: hydration, fine lines, dark circles, dark spots and pores. It's included four times a month, because skin changes slowly and a weekly check shows real progress, not day-to-day noise. YOUR PROGRESS TIMELINE. See each concern over time, with markers showing when you added a product, and compare any two Face Scans side by side, so you can see what's actually moving instead of guessing. YOUR ROUTINE AND SHELF. Save products to your AM and PM routine and SkinStack flags ingredient clashes across everything you use, not just the one thing you scanned today. MEL AI, YOUR SKIN GUIDE. Mel AI is the link between all of it. She sees your scans, Face Scans, goals, avoid-list, routine and shelf together, so when you ask "is this safe to layer with my retinol?", she answers from your real routine, not in the dark. She'll also tell you what to do next to get the most from the app. FAMILY PROFILES. Every family member gets their own routine, shelf and age-appropriate ingredient checks. Face Scan is for adults only. The more you use it, the smarter it gets. Every scan, every check-in, every conversation with Mel AI makes the next answer more personal. TRY IT FREE. Every plan starts with a 3-day free trial with full access. Cancel any time before it ends and you won't be charged. After the trial, SkinStack Premium renews monthly or annually at the price shown in your local currency when you subscribe. Barcode product information comes from Open Beauty Facts (openbeautyfacts.org), available under the Open Database Licence. SkinStack, including its Face Scan feature, is a cosmetic and educational tool, not a medical device. It does not diagnose, treat or provide medical advice, and nothing in the app replaces guidance from a qualified dermatologist or healthcare professional.
