The present invention relates to a skin-lifting cosmetic composition for anti-aging and a photothermal skin care method using same, the cosmetic composition containing, as an active ingredient, core-shell particles comprising: a magnetic core; a first shell layer surrounding the magnetic core and containing a dielectric substance; a second shell layer surrounding the first shell layer and containing a metal; and a third shell layer surrounding the second shell layer and containing a hydrophilic polymer. The skin-lifting cosmetic composition for anti-aging according to the present invention is applied to a photothermal skin care method comprising a step in which the core-shell structured microparticles, including a gold (Au) nanoparticle layer and contained as an active ingredient, infiltrate into follicles, sebaceous glands, pilosebaceous ducts, and infundibula of facial skin through ultrasound application and then are heated through light irradiation, whereby the cosmetic composition exhibits an enhanced skin lifting effect as well as outstanding skin anti-aging effects encompassing skin elasticity improvement, skin laxity reduction, and skin wrinkle relief.

Disclosed is a polypeptide having a base amino acid sequence and wherein at least two amino acid residue side chains are substituted with functional Michael acceptor groups. Also disclosed are cosmetic compositions including the polypeptide, a method for repairing damaged hair using the polypeptide or composition, and to the use of the polypeptide or composition in such methods.

The present specification relates to a method for extracting a plant by using a skin serum that can be used for skin care. This method can further increase the process efficiency and extract active ingredients more effectively than conventional extraction methods using a solvent. Thus, the method can increase customer satisfaction and promote the development of relevant industries.

In an ultraviolet-shielding particle coated with silicon oxide of the present invention, a surface of the ultraviolet-shielding particle is coated with a silicon oxide coat, at least one functional group selected from the group consisting of an alkyl group, an alkenyl group, and a cycloalkyl group is present on a surface of the silicon oxide coat, and a content of the functional group is 0.0001% by mass or more and 0.30% by mass or less.

Disclosed includes an ophthalmic composition for treating an eye condition and a method for treating an eye condition. The composition comprising a DNA repair enzyme, which can be administered to an eye of the patient in need. Some of the eye conditions that can be treated include glaucoma, optic neuritis, retinopathy, cataracts, macular degeneration, corneal abrasions or ulcers, melanomas, basal cell carcinomas, and other malignant or benign tumors.

There is provided a composition for teeth desensitization. The composition comprises from 1 to 15 wt. % of suspended crystals of oxalic acid potassium salt dihydrate having a size of from 50 nm to less than 1000 nm. The composition comprises from 0.5 to 10 g/L of NaOH and has a pH of less than 2.

A natural human shaker hair is offered to be efficiently applied to the balding spots and thinning areas of a user's scalp. The shaker hair comprises 100% natural human hairs and does not include any chemicals and/or man-made materials. The shaker hair is statically charged with negative electricity to not only allow easy application to the affected areas, but also cling to the user's scalp and existing hair. Thus, the shaker hair creates root lift and substantial kickstand support to the existing long hair of the user, and helps the user with desired styling. Further, an innovative method of making the all-natural human shaker hair is provided. The method prepares the shaker hair by cutting natural human hairs into hair granules and charging the hair granules with a charging machine. The resulting shaker hair charged with statically negative charge is placed into hair shakers and ready for use.

A preparation method for camellia extract includes the following steps: 1) Removing impurities from fresh camellia and/or fresh camellia buds, cutting the fresh camellia and/or fresh camellia buds into small sections for use as raw materials; 2) Placing a certain quantity of raw materials into a ultrasonic vessel, adding in a solvent having a mass ratio of 1:3 to 1:30 to form a mixture, uniformly stirring the mixture, and then adding in a certain amount of inorganic acid and/or organic acid to adjust the pH value to 1.3 to 3.0, then soaking the raw materials for 10 minutes to 30 minutes; 3) Performing ultrasonic treatment for 30 minutes to 60 minutes, controlling the ultrasonic frequency to be 20 KHz to 25 KHz, the ultrasonic power to be 1000 W to 2000 W, the ultrasonic temperature to be 15 C. to 50 C., then performing filtration, sterilization and detection to obtain camellia extract.

Single layer and multilayer vesicles with actives inside are delivered into living tissue. Then, the vesicles are disrupted using ultrasound. The vesicles are used to create an image in the tissue or for the delivery of certain actives to the skin.
