Indentation in skin.

Indentation tests were carried out on the forehead skin of volunteers under loading pressures of 0-5 KPa. The indentation was found to increase asymptomatically with loading pressure. In an attempt to develop a quantitative index for aging of the skin, its response to indentation loading was analyzed in reference to its glycosaminoglycan (GAG ... Upon indentation, the skin's elastin fibres are stretched and fluid is displaced from the compressed region. When the indentor is removed, the rate of recovery of the skin from this imprint is therefore principally dependent on its hydration and elasticity. Using the blue colour plane of the image and polarisation filtering, it is possible to ...The pit usually is located in the palm but also can be found in the fingers. This indentation occurs as the normal fibrous bands which hold the palmar skin in place shorten, drawing the attached skin deeper than the surrounding skin. The Cord: The cord is a longitudinal fibrous band, which extends from the palm into the finger(s).Pressing a textured pattern against the skin causes higher forces to be imparted on the skin by raised surfaces - resulting in more water being pushed aside in the tissues in and underlying the skin.
