What piel does

Three tools. One feedback loop.

01 · Selfie

A weekly skin scan from a single photo.

Once a week, take a selfie. Our vision model scores nine dimensions of your skin — hydration, clarity, redness, texture, dark circles, pigmentation, pores, wrinkles, firmness — in seconds.

02 · Journal

Track everything that touches your skin.

Sleep, stress, water, diet, exercise, sun exposure, products, period phase — logged in 30 seconds a day. The kind of data your dermatologist wishes they had.

03 · Correlate

See what's actually moving the needle.

After two weeks, piel surfaces the patterns. Your skin score drops on days you sleep less than six hours. Your texture improves on days you skipped sugar. The signal, not the noise.

Routines

Morning, night, weekly. Streaks that don't punish you for missing a day.

Product Scan

Snap any label. piel reads ingredients, flags conflicts, slots it into your routine.

How it works

A minute a day. A skin you understand.

01

One selfie a week.

Front camera, neutral light, no makeup. Five seconds. piel scores nine dimensions of your skin and tracks how they change week over week.

02

Log your day.

Sleep. Stress. Water. Diet. Sun. Products you used. Thirty seconds. The data your skin needs you to remember.

03

Watch the patterns emerge.

After a few weeks of data, piel surfaces correlations no human could spot. The hidden levers behind your best skin days.

The science

Built like a research tool, not a beauty app.

piel uses computer vision trained on dermatologist-labeled imagery to score nine clinical dimensions of your skin, then runs correlations across your own history. The only person you're compared to is the version of you from last week.

Real users. Real correlations.

I finally know that my skin tanks when I drink. I've cut Friday wine and my texture score is up 14 points in a month.

I was about to drop $200 on a new serum. piel showed me the redness flare started the week I added a different one. Saved me money and my face.

FAQ

The honest answers.

piel uses a vision model trained on dermatologist-labeled imagery. It's not a diagnostic tool — it's a tracker. Where it really shines is consistency: scoring the same dimensions on the same person, week after week, so you can see relative change over time.
