Transdermal Optical Imaging (TOI) extracts microvascular blood-flow patterns from the face using standard cameras, converting invisible optical signals into measurable physiological insights. This passive, non-invasive method generates continuous biometric data—revealing stress indicators, cardiovascular patterns, and autonomic responses.

Since human skin is translucent, light penetrates the skin. As light crosses through the skin’s tissues, it’s reflected and captured by a digital camera.  The TOI technology extracts facial blood flow data from the image. It does this using chromophores, which are the parts of a molecule that give it its distinct color. 

In the past, blood tests were needed to gauge these markers. However, new research is showing that TOI can be a helpful tool for predicting these blood biomarkers based on vital signs collected from facial blood flow. What they found is that TOI was a non-invasive and inexpensive way to identify the risk of abnormal blood markers. It also helps identify imbalances early on before chronic problems set in.

Research shows that transdermal imaging can detect subtle changes in blood flow,

offering insight into underlying physiological stress patterns.
