SkinStack AI

Your skin goals. One system that works toward them. SkinStack isn’t 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. Read any ingredient list against your actual skin: your type, concerns and sensitivities, not a generic average. Every scan is remembered, so it builds the picture instead of sitting in a history tab. 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. SKIN GOALS. Your first Face Scan and your latest are compared, concern by concern, so you can see what’s actually moving, not guess. 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, YOUR AI SKIN GUIDE. Mel is the link between all of it. She sees your scans, Face Scans, goals, routine and shelf together, so when you ask β€œis 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 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. 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.

Verdict

The call

The clearest difference is ads: PortionPal at none against SkinStack AI's shown. SkinStack AI's advantage is update cadence (weekly vs monthly) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.
