An instrumental approach enabling evaluation of efficacy of skin care products is disclosed. Common problems shared by existing methods include first the difficulty whether to test the entire human face, or just focus on the key locations (not determined yet); the difficulty in conducting a repeatable test when human face is hard to fix on and changes between different persons; and how many different skin attributes to test for making a reliable and complete judgment. The instrumental approach of the process tests a sample at once to obtain all the information needed. It shows good repeatability and sensitivity. It yields necessary yet sufficient information in numbers.

Process for evaluating skin care product efficacy and skin care product efficacy evaluation system

One embodiment of the present invention provides a process for fabricating an electrode for a capacitor using carbon nanotubes (CNTs), wherein the electrode comprises a metal substrate and a layer of active material (CNTs) coated onto the metal substrate. Specifically, the process starts by dispersing CNTs in a solvent to form a suspension. Next, the CNTs are charged in the suspension. The metal substrate is then immersed in the suspension. Next, the CNTs are deposited onto the metal substrate using electrophoretic deposition (EPD) to form the layer of active material on the metal substrate. In particular, the layer of active material is formed on the metal substrate without using a binder, which effectively reduces contact resistance between the active material and the metal substrate.
