What it isn't
Skintrig is a personal tracking tool, not a medical service, and not a one-size-fits-all product judge.
Not a diagnosis
Skintrig doesn’t diagnose conditions or provide medical advice. It helps you keep a clear history and spot patterns you can discuss with a dermatologist.
No universal product scoring
No green/red grades and no ‘safe/unsafe’ labels for everyone. Skintrig flags matches with your own history — otherwise it stays neutral.
Not a generic ingredient blacklist
We don’t push fear-based ‘bad ingredients’ lists. The same ingredient can be fine for others and a trigger for you — personalization matters.
Not magic AI guessing
AI helps extract and normalize INCI from labels. It doesn’t ‘understand your skin’. Insights come from what you log over time.
Not an instant verdict
Skintrig won’t pretend it can predict your skin from a single scan. It helps you learn from repeated exposure and real outcomes — the way triggers are actually discovered.
Not a cloud profile of you
Your products, reactions, and notes stay on your device. No account required. No personal skincare profile uploaded to a server.
It won’t tell you what to buy. It helps you learn what you tend to react to — and what to avoid.
Three steps to clarity
Scan, log, and review your history in one guided sequence.
1. Add products
Scan a label or paste INCI manually. Names are normalized in the background.
Usually under 10 seconds per product.
2. Log reactions
Capture intensity, area, and date whenever a reaction appears.
Tap once to rate intensity, then save.
3. Get insights
Review patterns and likely suspects based on your own history.
Every signal links back to dates and products.
Your past reactions become a shopping filter.
Insights first. Shopping second.
One scan turns your history into a warning system — helping you skip products that may trigger you and save money on 'maybe' buys.
- Avoid flare-ups before they happen
- Stop wasting money on 'trial-and-error' products
- Powered by your own logs (no generic product scores)
Heads-up
Found ingredients you've seen before your reactions.
Not a diagnosis. Use your judgment.
No match found
No ingredients linked to your logged reactions — based on your history.
'No match' ≠ guaranteed safe.
Privacy-first by design
- No account required.
- Core logs are stored on-device by default.
- AI is used only for reading and normalizing ingredient lists (INCI extraction).
- No diagnosis logic and no behavioral profiling for ads.
FAQ
Is Skintrig medical advice or a diagnosis tool? ↓
No. Skintrig is not a medical device and it does not diagnose conditions. It helps you organize your skincare history and surface patterns based on the data you log — nothing more. If you have persistent or severe symptoms, consult a dermatologist.
“No known triggers found” means the product is safe for me, right? ↓
Not necessarily. It only means Skintrig did not find a match with your current logged history. Skin is complex, formulas change, and reactions can depend on context. Treat it as a helpful signal — not a guarantee.
Do you recommend patch testing? ↓
Yes. Patch testing is a good baseline practice, especially if you have sensitive or reactive skin. Skintrig helps you learn from your past reactions, but it can’t replace patch testing or professional advice.
How accurate is ingredient scanning (OCR)? ↓
Accuracy depends mostly on the photo: sharp focus, good light, and a clear label. Skintrig is built for ingredient labels, but you’re always in control — you can review the detected INCI list and edit it before saving.
Do you store my photos? ↓
Your skincare log lives on your device. Photos are optional (for your convenience) and aren’t required for tracking. If you use scanning, the label photo is processed to extract ingredients — and the core tracking works from the normalized ingredient text.
Can I add products without scanning? ↓
Absolutely. You can paste an INCI list, type ingredients manually, or save a product without scanning at all. Scanning is there to save time, not to lock you into a workflow.
Does Skintrig work offline? ↓
Yes for tracking. Your products and reaction logs are stored on-device and work offline. Ingredient scanning requires an internet connection.
Is it free? ↓
You’ll be able to use 100% of Skintrig app features free during the beta. After launch, some features may require a subscription (via in-app purchase). We’ll always keep the core experience useful and transparent.
When is the beta / launch? ↓
Beta is planned for mid-end of March 2026. Join the waitlist and you’ll get an email when TestFlight access opens.
