What Patch does
- Check any product. Search a product and see each ingredient explained in plain language. Pore-clogging flags show how strong the evidence really is.
- Fungal acne checks. Flag fungal acne once and every product is checked for ingredients that can feed Malassezia.
- Rinse-off vs leave-on. Cleansers are judged differently from moisturisers, because most flagged ingredients wash away.
- Daily routine log. Tick off AM and PM products and log your skin in one tap.
- Breakout patterns. After two weeks Patch points out patterns, like breakouts that follow one product. It shows what it noticed and never claims a cause.
- Layering checks. See which products clash, like retinol with acids, and which popular rules are myths.
- Skin diary PDF. Share what worked and what didn't with a dermatologist or esthetician.
- Feedback board. Users suggest features, report bugs and vote on what gets built next.
Why it's different
- Free for everyone with no limits. Most ingredient apps lock key features behind a subscription.
- No ads and no ad tracking. Users get an anonymous username, never their real name.
- Evidence levels on every flag. Classic comedogenic lists rely on decades-old rabbit ear tests, so Patch says when the evidence is weak instead of scaring people off a product.
- Built around your own skin. Your log shows what actually happens to you, not a generic score.
