Poly-pseudo-lysine conjugates have been shown to be able to penetrate into human skin and are proposed for both therapeutic and cosmetic treatments by topical application, e. The cassette also includes a dispensing apparatus that defines a passage and has a first activating device that opens the valve of the cassette. This film functions as an optical path length adjusting layer. A material with a relatively high index of refraction combined with a prismatic structure having a modified prism geometry improves brightness. Moreover, the reference signal trace having a greater width may be used to reduce parasitic resistance within the reference signal circuit. The inner plate is made of metallic material and the outer plate is made of a structural fiber fabric incorporated in a thermoplastic material matrix.
