Skin Studies - Bio Physical Measurements
Share:
AMA LABS has a new and innovative skin study testing. The skin is the largest organ of the human body and it is the organ that forms the border between the organism and the environment. Skin prevents dehydration, stops the penetration of noxious foreign materials and micro-organisms, cushions against mechanical shock, helps to maintain a constant body temperature, and transmits incoming stimuli. Given the multitude of functions the skin is required to perform, it is of the utmost importance that skin is maintained in the best condition and health possible. Improving the pharmacology of skin and preventing damage to the skin is the job of skin-care scientists and cosmetic formulators. AMA Laboratories, Inc. provides a complete catalog of tests designed to determine the effects of products developed for use on human skin.
The use of several scientific methods is employed to determine the effect of a test product on wrinkles and wrinkled skin. These methods include both subjective and objective measurements, profilometry, macrophotography, microphotography; silicone replicates (quantification of cutaneous relief), three dimensional (3D) image analyses and the evaluation of "soft focus effect". AMA has developed a method to measure not only deep wrinkle depressions via optical micrometry, but superficial fine lines as well. Reports on these studies can also include visual documentation of our results.
These studies measure the relative moisture content of the skin utilizing a variety of state -of -the --art instruments to record stratum corneum hydration.
This test is used to measure a product's film forming capabilities (barrier effect)as well as evaluating the barrier function of the skin, by determination of the moisture gradient for water evaporating from the skin surface (the rate at which water is being lost through the epidermal layer of the skin).
