SkinTheory Skin + Acne Tracker

Stop guessing what's causing your acne. SkinTheory is an acne and skincare tracker that helps you spot patterns in your skin the way a scientist would: make a hypothesis, track it, and let your own data show you what's working.

Skin changes slowly. A new cleanser, a stressful week, a few short nights, extra dairy, your cycle: any of them could matter, and by the time a breakout shows up, you've already forgotten what changed. SkinTheory keeps the record for you, so you're not relying on memory and guesswork.

HOW IT WORKS

1. Hypothesis: Think dairy, poor sleep, a new product or your cycle might be the culprit? Start with a hunch.
2. Track: Do a quick daily check-in with skin photos, how your skin feels, your mood and a pimple count.
3. Analyze: Graphs line up your pimple count against everything else you log across your last 21 entries, so possible acne triggers start to stand out.

EVERYTHING IN ONE SKIN DIARY

- Progress photos from the front and both sides, so every day is easy to compare
- Skin feel and mood on a simple five-point scale
- Daily pimple count
- Your skincare routine: which products you use and how often
- Personal notes for anything else worth remembering
- A timeline of every entry, with weekly and four-week views to help you stay consistent

SEE YOUR BEFORE AND AFTER

Skin progress is hard to notice day to day. Put your photos side by side to see how far you've come, or pinpoint exactly when a flare-up started.

PRIVATE BY DEFAULT

Skin selfies are personal. Photos you take in SkinTheory are saved to the app, not your camera roll, so they won't pop up when you're showing someone your pictures.

GO DEEPER WITH LAB+

SkinTheory is free to download. Lab+ is an optional subscription that adds the usual suspects to your daily check-in:
- Period: see whether your breakouts follow your cycle
- Diet: log fast food, dairy, alcohol and protein
- Water intake: check whether drinking more actually shows up in your skin
- Sleep: see if short nights line up with worse skin days
- Exercise: see how your workouts line up with your skin

Give it a few weeks of check-ins and let your own data do the talking.

PLEASE NOTE

SkinTheory is a tracking and journaling tool. It doesn't diagnose, treat or cure acne or any other skin condition, and it isn't a substitute for advice from a dermatologist or doctor. If you're worried about your skin, please talk to a professional. Bringing a few weeks of photos and notes can make that appointment a lot more useful.

Lab+ is an auto-renewing subscription that renews unless cancelled at least 24 hours before the end of the current period. You can manage or cancel it anytime in your account settings.
