The present invention provides: a colloid having a self-iontophoresis capacity, comprising elastomer microparticles and a piezoelectric layer encompassing the same; a preparation method therefor; and a cosmetic composition containing the same. According to the present invention, iontophoresis occurs by itself without the help of additional instruments, thereby allowing water-soluble active ingredients in a cosmetic composition to be effectively and transdermally delivered and absorbed.

Provided are the reactive topical skin protectant formulations including: water or moisture; plate-like inorganic particle powder; and one or more selected from the group consisting of a) liquid perfluoride, b) polyol, c) perfluorinated polymer powder, d) polysaccharides, e) liquid silicon-based material, and f) additives, and the reactive topical skin protectant formulations may provide an effect of safely protecting the skin from various lesions and risks occurring by liquid chemical agents or harmful toxic substances penetrating the human skin.

This invention relates to novel methods of improving the overall outcome of a dermal tattoo when it is applied, such methods including applying a silicone-based material (such as a silicone-based film or silicone ointment) to a freshly created tattoo to improve comfort, offer barrier function, promote moist healing, and provide an effect to prevent and reduce scar formation. The invention also relates to a novel method of improving the overall outcome when a dermal tattoo is removed, such method including applying a silicone-based material to the tattoo site as a pre-treatment to laser tattoo removal.

An apparatus and method for depositing a particulate containing composition onto mammalian skin such that when the particles contact the mammalian skin they have a momentum defined by vr, which is within the range of about 0.1 kg/msvrabout 12.0 kg/ms. The particles can be in the range of from about 10 nanometers to about 10 micrometers, in size. And the particles may be selected from the group consisting of titanium dioxide, zinc oxide, iron oxide, polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, polyvinyl chloride, glass, silica and mixtures thereof. The particles are imbedded below the first layer of dead skin cells in the stratum corneum but they do not pass all the way through the stratum corneum into the living cells of the epidermis or dermis layers of the skin.

Methods and compositions for use in tissue volume replacement are provided. The present invention comprises compositions comprising a combination of materials, comprising preferably a solid polymer particle phase and a gel phase, and also comprises single phase compositions. More particularly, preferred embodiments comprise a solid polymer particle phase made of materials comprising Gore-Tex (micronized e-PTFE), PDS II (polydioxanone, a monofilament), NUROLON (a long chain aliphatic polymer Nylon 6 or Nylon 6,6) ETHILON (a long chain aliphatic polymer Nylon 6 and Nylon 6,6), PROLENE (Polypropylene, isotactic crystalline stereoisomer of polypropylene, a synthetic linear polyolefin.), VICRYL (copolymer made from 90% glycolide and 10% L-lactide), silk, MONACRYL (poly -caprolactone.), polylactide, polyglycolide, poly lactide-co-glycolide, and BIOPOL (polyhydroxyvalerate), MEDPOR (biocompatible (micronized) polyethylene), BIOGLASS (bioactive glass particulate), NOVABONE and NOVABONE-CM, and the gel phase comprises polyvinylpyrrolidone (PVP). Preferred single phase compositions comprise PVP. Methods of the present invention comprising injection of such compositions for tissue augmentation.

The present invention relates to a foam made of a specific material having superior properties and to cosmetics comprising said foam.

The present invention relates to a foam made of a specific material having superior properties and to cosmetics comprising said foam.

Provided is a cosmetic sheet, including a support and a membrane, which is provided on the support, is attached to the skin, and is formed by arranging a fiber containing a water-soluble polymer, a water-insoluble polymer, and a functional material for skin care that is released by the dissolution of the water-soluble polymer.

The invention relates to a composition, especially a cosmetic composition, including water, at least one film-forming agent, at least one volumizing agent, and an emulsification system comprising (i) about 2% to about 6% of low HLB emulsifier(s) (HLB value less than 8), (ii) about 2% to about 8% of intermediate HLB emulsifier(s) (HLB value of 8 to 16), and (iii) about 1% to about 8% of high HLB emulsifier(s) (HLB value greater than 16), with the compositions further including at least one colorant and/or excluding wax, as well as to methods of using such compositions.

A two-part treatment film may include a barrier layer, a gelatinous composition layer, and at least one active ingredient adhered to the gelatinous composition layer. The barrier layer may be a flexible film that is insoluble in water. In some embodiments, the at least one active ingredient may be in the form of dried particles. In other embodiments, the at least one active ingredient may be in the form of microspheres filled with an active ingredient.
