About this app

Piel tells you what is actually in your skincare — and whether it suits your skin.

Look up a product and Piel breaks its ingredient list down into plain language: what each ingredient does, which ones are well documented, and which are worth a second look. Then it checks that product against the skin you told us about, and against everything else in your routine.

DECODE ANY PRODUCT
• Search skincare and cosmetics by name or brand.
• A full ingredient breakdown, explained without the jargon.
• What it actually does — effects backed by published evidence, not marketing copy.
• Skin fit: how a formula suits your skin type, your concerns and your allergens.
• The Halo, a 0–100 read you can compare at a glance.

BUILD A ROUTINE THAT DOESN'T CLASH
• Lay out your morning and evening steps in order.
• Piel checks the routine as a whole, not one product at a time.
• Clashes between steps are flagged, with the reason why.
• Pairs that get called conflicts but are actually fine are called out too.

YOUR SHELF
• Keep track of what you own, what you have finished, and what you are eyeing.
• Every product carries its verdict, so your shelf doubles as a shortlist.
• Build your routine straight from the shelf.

SUNSCREEN REMINDERS THAT FOLLOW THE UV
• Log the SPF you put on and Piel works out when to reapply.
• Reminder timing follows the real UV index where you are.
• When UV is low, Piel stays quiet instead of nagging you.

TRACK HOW YOUR SKIN RESPONDS
• A one-tap daily check-in — words optional.
• See the calm stretches and the rough patches on a single heatmap.
• Something feels off? Log it, then look back for the culprit.

PIEL PREMIUM
A Piel Premium subscription adds:
• Piel assistant — ask about the product in front of you and get an answer grounded in its real ingredient list and your skin profile. Answers are written by an AI model run by Anthropic. The assistant stays off until you turn it on, and Piel shows you exactly what it would send before anything is sent.
• Progress photos — taken inside Piel and kept in private app storage, off your camera roll and behind your phone's fingerprint, face unlock or passcode. Compare two dates side by side.

PRIVATE BY DESIGN
• Continue with Google, with email, or keep exploring as a guest.
• Your skin profile is never used for advertising, and we do not sell your data.
• Delete your account and its data from inside the app, whenever you want.
• Available in English and Spanish.

Piel is an informational skincare tool. It provides general cosmetic product information and is not medical advice or a diagnosis. Please see a qualified professional for medical concerns.
