Morphological, structural and biophysical properties of French and Brazilian photoaged skin

Abstract

Morphological, structural and biophysical differences were found when assessing the skin of the Brazilian and French participants, who were exposed to different environmental factors.

Characterization of oily mature skin by biophysical and skin imaging techniques

“…All these observed changes are visible in the ultrasound image, presented on Figure . The higher values in the dermis echogenicity are a parameter related to better dermis condition …”

“…Extrinsic aging is variable, controllable, and cumulative over time. The most known factor that intensifies the extrinsic aging is the excessive sun exposure that changes the architectural, cellular, and extracellular matrix properties of the skin . Aside from sun exposure, we can mention smoking, pollution, alimentary, and sleeping habits as other extrinsic factors that affect skin conditions.…”

Assessment of skin pigmentation by confocal microscopy: Influence of solar exposure and protection habits on cutaneous hyperchromias

“…The results of the questionnaires were important for the next step of the present study, that is, the assessment of the differences in the epidermal pigmentation pattern according to photoprotection habits. The questionnaires can be used to correlate different skin alterations with photoprotection habits and can help to select volunteers with similar profiles, thus ensuring more comparable data …”

The social and scientifical evolution of the cosmetic science – a brasilein view

“…Além disso, as propriedades sensoriais e sua influência no uso de cosméticos começaram a ser estudadas. Com a associação de cosméticos com conforto, o ato de esfregar e this excessive sun exposure, presenting more photodamaged areas than the French skin, for example 29 .…”

“…Além disso, a exposição ao sol era intensa e a proteção era quase inexistente, o que levou a uma cultura que se perpetua até o presente dia na sociedade e ajuda a aumentar a incidência de condições de neoplasia da pele 27,28 . Estudos mostraram que a pele madura brasileira sofria as consequências dessa exposição excessiva ao sol, apresentando mais áreas com danificadas pelo sol do que, por exemplo, a pele francesa 29 .…”
