How you look is a complex interaction between the light that falls on your skin and how it interacts with different skin constituents.
Our new whitepaper outlines an analytical model for light-tissue interaction that allows analysis of the reflected spectrum to predict different skin constituents. This has applications within the cosmetics industry and within the medical sector. This model enables the design of low-cost sensors to measure specific skin constituents. For example, to measure melanin concentration we can use the model to design a sensor that is most sensitive to melanin, whilst the cross-talk from other constituents is minimised.
The analytical model is being used to develop low-cost sensors that will help move measurements which are traditionally carried out in the lab or clinical settings into the home environment to offer consumers a much more personal experience.
