PIV: Acne Care via Skin Diary

Figuring out what's behind a breakout isn't easy. Even when you use the same products, your overall condition, diet, sleep, and changes in your environment all work together to affect your skin. PIV is a skincare app that makes it easy to log the many factors that influence your skin every day, so you can understand how your skin changes through the data you build up over time.
■ How's your skin today? Keep a skin diary

Create a daily entry with just one photo and a few quick taps.

Log not only your skin's condition and concerns, but also the skincare products you used, what you ate, your menstrual cycle, doctor visits, and more.

The more you record, the easier it becomes to see when and why your skin gets better or worse.
■ Your skin diary, turned into graphs

Every entry becomes data. The Summary tab shows how your skin's condition changes over any period in easy-to-read graphs, and you can see the ratio of good days to bad days across the month at a glance.

Compare your records to see exactly how your skin changed after trying a new product or adjusting your daily habits.
■ See your skin's changes with your own eyes

PIV automatically adjusts the angle and tilt of each photo as it saves them, and the Gallery tab collects them in date order. Pick any two photos to view side by side and check your skin's progress for yourself.
■ Manage your skincare routine, too

Register the products you're currently using, and you can pull them up instantly when writing a diary entry.

No need to type product names every time, so logging is even easier.
The more you log, the deeper your understanding of your own skin becomes. Start your skin diary today with PIV!
