Precision Skincare & Beauty Technology
Our patent-pending patch design is pre-filled with ingredients commonly found in skincare and cosmetic products. It applies easily to the skin, and it's water resistant - so it's ready to take on the day, with you.
How it works
Create a profile on our app.
Your user profile works with our AI so that we can match the right products to your skin once the patch test is complete.
Apply the patch.
Apply the patch on Day 1 to clean, uninjured skin anywhere that is comfortable - we suggest the outer arm. The patch is water resistant and flexible so you can continue your regular daily routine. The patch stays on you for 48 hours.
Take a photo with our app.
Remove the patch on Day 3, then on Day 5 our app will help you take a photo. Our patent-pending AI also helps with image alignment.
Get your test results.
Our patent-pending AI technology analyzes the photo to suggest the best ingredients for you. Learn about your skin, and where these ingredients are found.
