The cosmetic appearance of skin
is directly linked to the state of its outermost layer,
the stratum corneum. The water-content of the stratum
corneum influences its permeability and elasticity.
Most skin-care products such as moisturizers act to
increase the retained water content of this layer of
the skin to enhance its appearance. Quantitative characterization
of the hydration-level of the stratum corneum is thus
of crucial importance to the cosmetics industry in
order to characterize and compare the effectiveness
of their
products.
In partnership with an industry-leading cosmetics manufacturer,
TeraView performed the first investigation of the application
of terahertz pulse imaging for in vivo characterization
of stratum corneum.
TeraView has worked with clinical
collaborators to establish the ability of Terahertz
to distinguish
between basal cell carcinoma and other forms
of malignant,
benign and healthy tissue associated with skin
cancer and related diseases. Both extensive ex vivo
measurements
for tissue classification and histopathological
use, and preliminary in vivo measurements directly
on
patients have been successfully performed.
