TEST THE ACTIVE VITAMIN C % IN YOUR SERUMS & MOISTURIZERS

Air, light, and water may be living necessities, but they also kill ingredient potency. We encourage you to test the % of Vitamin C in your products over time to ensure you’re still getting optimal results. Keep in mind that 5% and less delivers minimal benefits while over 10% can cause irritation. 

KIT INCLUDES

10 test strips — packed in a vacuum seal to stay fresh — and the corresponding guide to read your results.
