  • Publication number: 20210000730
    Abstract: The present disclosure relates to a composition for improving optical characteristics of skin, which improves changes of optical characteristics of skin and skin texture, changes of skin tone such as dullness, and the like, caused by progress of keratinization, by applying an optical clearing agent to skin, and thereby, it comprises an optical clearing agent in the composition, thereby having an effect of reducing crystallization of constituents as the optical clearing agent penetrates between keratinocytes, and reducing light scattering as the substance for improving optical characteristics penetrated in the keratinocytes remains in the keratinocytes and binds to water, and through this, improving skin clearing, skin tone and skin texture, and therefore, it may be very usefully used as skin external preparation and cosmetic compositions.

  • Publication number: 20190060205
    Abstract: The present disclosure relates to a networked dispersion of biocellulose microfibrils in water wherein the biocellulose microfibrils have carboxylic groups substituted for alcohol groups, are 30-60 nm in number average diameter with a maximum diameter of 60-100 nm, and are dispersed in an aqueous phase while forming a network. The networked dispersion of biocellulose microfibrils in water according to the present disclosure exhibits excellent skin compatibility and has the effect of allowing the skin to increase in water absorption, elasticity and smoothness. In addition, not only does the networked dispersion of biocellulose microfibrils in water form micro-networks on the skin to prevent microdust from being brought into direct contact with the skin, but also negative charges of the networked dispersion repel those microdust to reduce microdust attachment, so that the present disclosure can be widely utilized in developing a variety of compositions for effectively blocking microdust.

  • Publication number: 20160137697
    Abstract: The present invention relates to a fusion protein comprising a skin-penetrating peptide, a polynucleotide encoding the fusion protein, an expression vector comprising the polynucleotide, a transformant comprising the expression vector, a method for preparing the fusion protein, a cosmetic composition for improving skin conditions, which comprises the fusion protein, and a pharmaceutical composition for external skin use, which comprises the fusion protein. The fusion protein of the invention comprises a skin-penetrating peptide bound to a physiologically active protein. The fusion protein significantly enhances the skin penetration and skin retention of the physiologically active protein while maintaining or enhancing the ability of the physiologically active protein to synthesize a material showing physiologically active effects. Thus, it can be widely used as an active ingredient in functional cosmetic compositions and pharmaceutical compositions for external skin use.
