Delivery of compositions for treatment of skin tissue with photoactive plasmonic nanoparticles and light, with embodiments relating to delivery devices. Treatments are useful for cosmetic, diagnostic and therapeutic applications.

The present invention is directed to depilatory compositions comprising a depilatory active, alkali metal hydroxide and an aminoalkylpropanol. The compositions have a pH in the range of from 10 to 12.5. The depilatory active preferably contains a thiol group, the alkali metal hydroxide preferably comprises potassium hydroxide and the aminoalkylpropanol preferably comprises aminomethylpropanol. The composition is preferably a gel, mousse, foam, cream, lotion or peelable film, especially a translucent or transparent gel. The depilatory compositions provide effective hair removal yet are well tolerated by the skin and allow for acceptable application times of the composition. The present invention further provides a depilatory composition comprising urea, a carbomer, and a gum; these compositions may or may not comprise aminoalkylpropanol.

The present invention provides compositions comprising energy (e.g., light) absorbing submicron particles (e.g., nanoparticles comprising a silica core and a gold shell) and methods for delivering such particles via topical application. This delivery is facilitated by application of mechanical agitation (e.g. massage), acoustic vibration in the range of 10 Hz-20 kHz, ultrasound, alternating suction and pressure, and microjets. The method of treatment is performed and then, depending upon the desired clinical outcome, repeated after a treatment response interval has elapsed.

A siloxane polymer base that is useful as an excipient for many variable materials that can be compounded into it. Also disclosed are a method for the preparation of such bases, and another method regarding the preparation of the base and actives.

The present invention relates to a method for treating skin, comprising the following step A) and then step B): A) physically or chemically treating an epidermis of the skin; and B) forming a film containing a fiber deposit on the skin which has been subjected to the step A). When the above step B) is applied to the skin after the conventional step A), skin conditions such as inflammation, redness, and swelling caused by the step A) are alleviated, these conditions disappear more quickly, and the quality of life (QOL) of persons who have undergone the cosmetic or dermatological treatment is significantly improved.

The present invention provides an epilatory composition comprising an admixture of a hydrocarbon resin material and a mineral oil in weight ratio of 1.3:1 to 2.8:1, particulate silica, and, a polyethylene in the form of a homopolymer. An advantage of the compositions of the present invention is that they are able to provide good grip to the hair to be removed and so provide for effective hair removal properties.
