Precision Skincare & Beauty Technology
All Skin's at-home cosmetic patch test and mobile app can be used anytime, anywhere to help you find the best skincare and cosmetic products for your skin needs. With All Skin's smart AI technology, we'll help you find products that are right for you.
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 helps to match the right products to your skin once your cosmetic 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.
