Objectives We described the ultrasound (US) signs that can define the occupational photoaging skin. We also studied the clinical importance of these signs, so to help the specialist in the diagnosis and evaluation of “anti-aging” treatments. Patients and Methods The dermis and hypoderma of 180 subjects (6 groups of 15 men and 15 women everyone), were studied with US test (ecographo Sonora 400MD). We emploied a 10 MHz probe and recorded the thickness and ecogenicity of the dermis and hypoderma. US images were correlated with hystological findings of 60 patients. Results The aging produces in the non sunlight skin increase in thickness and reduction in ecogenicity, while in photoaging skin reduction in thickness and increase in ecogenicity. Conclusion The photoaging produce increase in elastic fibers and therefore the hyperecogenicity of the dermis, while, in advanced phase, the loss of collagene and elastic fibers justify the reduction in thickness and ecogenicity of the dermis. These observations allow as to define the US signs of the photoaging skin in four clinical-ultrasound stages.
