The Antioxidants Scan is a fast, non-invasive measurement using Prysm iO technology that determines the level of carotenoids stored in your skin in just a few seconds. Carotenoids are important antioxidants that we primarily obtain from fruits and vegetables. They help protect cells from the effects of free radicals and serve as an indicator of the body's antioxidant status. Prysm iO uses advanced optical scanning to track how different wavelengths of light interact with the skin. The result is a simple Prysm Score, which allows you to track your skin carotenoid levels and how they change over time. This measurement is particularly valuable as a long-term indicator—you can observe how your diet, lifestyle, supplementation, and other factors affecting your body's antioxidant status are reflected in your results.
Get a non-invasive measurement of your skin carotenoid levels in just a few seconds—no needles, no pain, and no lab work required.

You will receive your Prysm Score, which provides a simple overview of your current carotenoid levels and your body's antioxidant status.
By measuring regularly, you can track your own trends and see how changes in your diet, supplementation, and lifestyle impact your score.
First, we will explain what carotenoids are, why they are important for your body, and exactly what the Prysm iO measures.
You place your finger on the Prysm iO sensor. The device uses light to measure the level of carotenoids in your skin—no needles, no blood draws, and no pain.
You will receive your score in just a few seconds, reflecting your current skin carotenoid levels.
We will provide context for your results, explain how to read them, and highlight the factors that can influence your carotenoid levels.
Prysm iO uses hyperspectral optical scanning. The device emits light of various wavelengths into the skin and analyzes the characteristic absorption patterns associated with the presence of carotenoids. The measured data is then processed by an algorithm using machine learning calibration to generate your Prysm Score. The entire measurement is quick, painless, and requires no blood or other biological samples. The Prysm Score is most valuable when repeated regularly. Instead of a single number, you can track the trend of your antioxidant status over time.
One objectively measurable indicator is the level of carotenoids stored in the skin. Prysm iO can measure these non-invasively using an optical scan. The result is a Prysm Score, which allows you to track your skin carotenoid levels and their development over time. However, this is not a measurement of all antioxidants in the body.
Oxidative stress occurs when there is an imbalance between the production of reactive molecules and the body's ability to neutralize them. Antioxidants are part of the natural defense system that protects cells from oxidative damage. Carotenoids are antioxidants primarily obtained through diet, and their levels can be monitored non-invasively in the skin.
Prysm iO uses hyperspectral optical scanning. By using different wavelengths of light, it analyzes absorption patterns in the skin related to the presence of carotenoids. The measurement is non-invasive, painless, and takes only a few seconds.
Repeated Prysm iO measurements allow you to track whether your skin carotenoid levels change over time. It can be a useful tool when changing your diet, increasing your intake of fruits and vegetables, or starting supplementation. However, the result cannot be used to assess the efficacy of a specific dietary supplement.
An important source of carotenoids is a varied diet rich in colorful fruits and vegetables, such as carrots, tomatoes, peppers, squash, leafy greens, or apricots. Your final carotenoid level is influenced not only by your intake but also by your individual metabolism and other lifestyle factors.
A one-time Prysm Score captures your status at a specific moment. Repeated measurements allow you to track trends and better see whether changes in your diet and lifestyle are reflected in your skin carotenoid levels over time.
Prysm iO is a non-invasive optical measurement that requires no needles, electrical impulses, or blood draws. However, it is not a medical or laboratory examination, and the results are not intended to diagnose diseases, vitamin deficiencies, or other health conditions.
