The application belongs to the technical field of microorganisms and particularly relates to a Bifidobacterium adolescentis beneficial to skin, a derivative of the Bifidobacterium adolescentis and application of the Bifidobacterium adolescentis and the derivative. The derivative of the Bifidobacterium adolescentis has significant antioxidant and anti-inflammatory effects, can inhibit pathogenic bacteria of acne and other common skin infections such as Propionibacterium acnes, Staphylococcus aureus and Malassezia furfur, can eliminate pathogenic bacteria, can inhibit skin lipid accumulation, can avoid follicle blockage, and can improve skin problems in multiple directions, especially acne skin problems.

The present application belongs to the field of polypeptide drug preparation, and particularly relates to a kind of short peptide dimer and its nanocomposite.The tripeptide (Ser-Cys-Arg) is assembled to form short peptide dimer by hydrogen bond in aqueous solution, which first discloses that short peptide forms cyclic dimer structure through intermolecular hydrogen bond, without using chemical crosslinking agent, oxidizing agent or protection / deprotection step, and the process is more simple and mild, and more suitable for synergistic assembly with drug molecules to form nanocomposite.The short peptide dimer provided by the present application can efficiently encapsulate model drugs to form "peptide-drug" nanocomposite, which can diffuse in gel matrix to epidermis, form multiple non-covalent interactions with skin lipids and keratin, significantly improve the transdermal permeability of drugs through dual pathways of cell penetration and intercellular gap transport, and reach the action site to realize efficient targeted drug release.

The present application relates to a plant extract-based liposoluble antioxidant and skin lightening composition and its skin care product. The plant extract-based liposoluble antioxidant and skin lightening composition comprises the following components by mass fraction: 5-50 of deep sea fish oil, 0.05-2 of tomato fruit extract & jojoba seed oil & squalane compound, and 0.05-1 of jojoba seed extract & olive fruit oil compound. The present application improves the skin lipid content through the synergistic effect of deep sea fish oil, tomato fruit extract & jojoba seed oil & squalane compound, and jojoba seed extract & olive fruit oil compound, resists oxidation in multiple dimensions, removes free radicals, reduces collagen loss, inhibits melanin production, increases skin hyaluronic acid content, enhances the ability of cells to resist oxidation, improves the glossiness and elasticity level of skin cells, and ultimately achieves the effects of antioxidant and overall whitening and skin lightening.
