The present invention can achieve an effect of repairing the skin, and the combination of active substances with the hydrogen injected has a prominent effect on reducing the amount of allergic erythema and alleviating the recurrent allergic redness and rashes.

An external skin preparation comprises the following components (A) to (E), wherein the mass ratio of the component (A) to the component (B), (A)/(B), is from 0.3 to 2.0, wherein the content of the component (C) is from 0.1 to 1 mass %, and wherein the preparation has a pH at 25° C. of from 4.0 to 7.0: (A) one or more selected from the group consisting of aliphatic alcohols having from 14 to 20 carbon atoms; (B) two or more selected from the group consisting of polyhydric alcohol fatty acid ester-type nonionic surfactants; (C) one or more selected from the group consisting of N-acyl amino acids, N-acyl taurine, salts thereof, and phospholipids; (D) one or more selected from the group consisting of steroidal anti-inflammatory drugs, non-steroidal anti-inflammatory drugs, and heparinoids; and (E) water.

Compositions for dermal delivery of a topical solution and methods for using such compositions are described herein. The compositions may contain extracellular matrix components and therapeutic peptides.

Described herein is a nanofibre matrix comprising 100% natural biopolymers selected from polysaccharides and/or proteins with optional functional ingredients for use as cosmetic products. More specifically, nanofibre matrix manufactured by electrospinning methods comprising a dry sheet without containing any preservatives, surfactants, solvents and crosslinkers. To use nanofibre cosmetic products, simply wet skin and then apply the nanofibre to skin. Functional ingredients may be optionally incorporated within the nanofibre matrix during electrospinning to provide different cosmetic effects. Functional ingredients offer skin benefits such as moisturizing, anti-ageing, wrinkle reduction, brightening, antioxidant and acne treatment. Functional ingredients can be essential oil where it is incorporated into nanofibre matrix to provide scent effect to cosmetic products. Functional ingredients can also be natural dye where it is incorporated in nanofibre matrix to make coloured nanofibres. Coloured nanofibres can be used for makeup products such as blush, eye shadow, eyebrow, nail polish, lipstick, contouring and hair dye product. The nanofibre matrix comprising 100% natural biopolymers with or without functional ingredients can be processed to assorted shapes or easily cut by consumers for using on different areas of skin for different purposes.

The present invention concerns a method to prepare a filler with a hyaluronic acid, which has improved properties of chemical-physical stability over time and optimal viscosity for cutaneous injection. In particular the method comprises a first step in which the hyaluronic acid is crosslinked, and a subsequent step for the neutralization and hydration of the crosslinked hyaluronic acid.

The present invention provides a simple method for producing a medical/cosmetic sheet that is excellent in adhesion to skin or the like and sense of wearing, and is capable of releasing a functional component gradually and supplying it continuously to a treatment area or the like, and a medical/cosmetic sheet produced by this production method. Provided is a method for producing a medical/cosmetic material including a step of shaping a raw material containing a water-soluble salt of a first polyanionic polysaccharide having a viscosity-average molecular weight of 10,000 or lower, and a water-soluble salt of a second polyanionic polysaccharide having a viscosity-average molecular weight of 50,000 or higher, and thereby obtaining a water-soluble shaped body. A medical/cosmetic material produced by this production method is also provided.

The invention relates to a hydrogel product comprising glycosaminoglycan molecules as the swellable polymer, wherein the glycosaminoglycan molecules are covalently crosslinked via crosslinks comprising a spacer group selected from the group consisting of di-, tri-, tetra-, and oligosaccharides.

The inventions relate to cosmetology and are intended to increase a cosmetic effect. A mask comprises a cream-type cosmetic agent and an additional reagent, which are isolated from one another. The agent contains a water-soluble biocompatible polymer which has a mass in the range of 50,000-1,000,000 Da and is capable of entering into a cross-polymerisation reaction. The reagent consists of a substance-electrolyte solution containing multicharged ions. The mass ratio of polymer and substance-electrolyte is from 10:1 to 1:1 respectively. A method involves separately applying to the skin the cream-type agent and then the additional reagent on top.

An upconversion nanoparticle includes at least one host selected from LiYF.sub.4, NaY, NaYF.sub.4, NaGdF.sub.4, and CaF.sub.3, at least one sensitizer selected from Sm.sup.3+, Nd.sup.3+, Dy.sup.3+, Ho.sup.3+, and Yb.sup.3+ doped in the at least one host, and at least one activator selected from Er.sup.3+, Ho.sup.3+, Tm.sup.3+, and Eu.sup.3+ doped in the at least one host.
