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.
Transepidermal Moisture Loss TEML
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).
