Trace: Acne & Skin Tracker

See if your skincare is actually doing anything.

Trace turns a daily selfie into four simple numbers, so you can watch your skin over weeks instead of guessing in the mirror every morning.

HOW IT WORKS
1. Scan your face. It takes about two seconds.
2. Keep your routine steady and change one thing at a time.
3. Watch the line. Weeks tell you what a single day never can.

WHAT YOU SEE
Four scores, each 0 to 100, where higher always means calmer and clearer:
Acne, Redness, Pores, Spots.

Plus a trend line for each, a daily note from your Trace buddy, and a report at the end of every test.

ONE THING AT A TIME
Change three products at once and your skin improves, and you have learned nothing. Trace is built around changing one variable while everything else holds still. It is slower. It is also the only honest way to find out what worked on your face.

YOUR SCAN RUNS ON YOUR PHONE
Your four skin scores are measured on your iPhone, so scanning never sends your photo anywhere. Photos sync only to your own private account. Optional AI features, like product recommendations, send a photo only when you choose to use them.

TALK TO IT LIKE A DIARY
Tell Trace what you ate, how you slept, whether you were stressed, travelling, or on your period. It lines all of that up against your skin trend, so you can tell a product effect from ordinary life noise.

WHY WEEKS, NOT DAYS
Adult skin renews itself over roughly 28 days, and most active ingredients need four to six weeks before anything real shows up. One day of wiggle means almost nothing. The line means a lot.

WHAT TRACE IS NOT
Trace measures, it does not diagnose. The scores describe what the camera saw in this light, on this day. They are not a medical assessment. If something about your skin worries you, please see a dermatologist.

FREQUENTLY ASKED

Q: Does scanning upload my face to an AI server?
A: No. Your four scores are measured on your iPhone. Photos sync to your own private account. Optional AI features send a photo only when you choose to use them.

Q: How soon will I see something?
A: Give it a few weeks. Day to day movement is normal and expected. The trend is the part worth reading.

Q: Can I test more than one product at a time?
A: You can, but then you will not know which one did it.

Q: What if I miss a day?
A: Nothing breaks. Come back and keep going. The line survives gaps better than you would think.
