Abstract: A process for improving the penetration of at least one pharmaceutical active agent into the skin, including formulating at least one volatile silicone, a non-volatile oily phase and a pharmaceutically acceptable alcoholic vehicle herewith, and spraying the formulation onto the skin of an individual in need of such treatment.

Abstract: Sprayable pharmaceutical compositions suited for improved transdermal penetration contain a) at least one bioactive agent, notably at least one derivative of vitamin D, (b) at least one volatile silicone and c) a non-volatile oily phase, formulated into d) a pharmaceutically acceptable vehicle therefor.

Abstract: Compositions in the form of a spray contain a pharmaceutical active agent, at least one volatile silicone and a non-volatile oily phase, formulated into a physiologically acceptable medium, are well suited for improved transdermal administration in cosmetics and dermatology.

Abstract: The invention relates to device making it possible to apply a chromophoric composition to the skin, said device including a chromophoric composition containing at least one chromophoric agent. The chromophoric composition is in the form of a layer of constant thickness bonded to one face of backing, at least prior to being applied to the skin, the chromophoric agent or agents being distributed uniformly in said composition, and the type of the composition being chosen such that light energy from laser radiation is transformed locally into heat and/or the chemical structure(s) of the chromophoric agent(s) is/are modified locally.

Abstract: Mammalian skin is treated and advantageously smoothed, for example to remove wrinkles, lines, warts and scars therefrom, by topically applying thereto a composition which comprises at least one laser-absorbing chromophore formulated into a physiologically acceptable carrier, diluent or vehicle therefor, and laser-irradiating the skin thus treated with an intensity sufficient to locally convert the light energy into heat energy in the applied composition and advantageously effecting tissue ablation of the surface of the treated skin, said applied composition and the thickness thereof having an absorbance at the emission wavelength of the laser such that the light energy transmitted into the skin generates no undesired irreversible tissue or cell damage.
