Abstract: A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes a cathode active material and a conductive material ID/IG is in a range from 0.5 to 1.25 in a Raman spectrum of the cathode active material layer. The cathode active material includes lithium metal oxide particles containing nickel and manganese and having a content of cobalt of less than 2 mol % among all elements except for lithium and oxygen.

Abstract: The present invention relates to a low-viscosity cosmetic composition and methods using a natural emulsifying agent. More specifically, the present invention relates to a cosmetic composition using a naturally derived saccharide-based surfactant in place of a chemical surfactant and realizing a low-viscosity formulation to offer safety to the skin, feel good on the skin with fast absorption, give stability to the formulation and add luster to the skin in an effective manner.

Abstract: The present invention relates to a composition for promoting hair growth and hair restoration containing psoralidin or a derivative thereof, which can be widely used as an external skin preparation for promoting hair growth and hair restoration, a cosmetic composition or a pharmaceutical composition, as the composition has high stability for skin without side effects and is very effective in promoting hair growth or preventing hair loss by activating stem cells.

Abstract: Provided are an anti-aging composition that contains a mixed extract of Chinese matrimony vine and pine needles as an effective component and a method of inhibiting aging of skin. The composition is for an external application to the skin, wherein a mixed extract of Chinese matrimony vine and pine needles, which are the natural ingredients, is contained such that excellent anti-aging or wrinkle improvement effects to the skin can be obtained through the vitalization of a retinoic acid derivative.

Abstract: The present invention provides a cosmetic composition containing one or more selected from a group consisting of green tea saponin and green tea polyphenol as active ingredients. The cosmetic composition of the invention is very safe to the skin and can greatly enhance biological mechanisms in the skin, and thus can serve as an anti-aging cosmetic composition.

Abstract: The present invention relates to a cosmetic composition for skin whitening containing at least two selected from the group consisting of a Magnolia obovata bark extract, a Citrus unshiu peel extract, a wild soybean extract, a Ginkgo biloba leaf extract, and a Honeysuckle extract, which composition depresses melanocytes, blocks stimulation from inflammation, UV radiation, or melasma blood vessels, strengthens melanocyte-supporting DEJs, inhibits skin hyper-pigmentation like skin spots and UV-induced skin tanning, and improves the skin tone and complexion look healthy and bright.

Abstract: The present invention relates to a method for evaluating the improvement of skin elasticity by preparing a mimetic dermis having a structure similar to that of the real dermis, and providing a three-dimensional visualization of the differences in the degree of transformation of the mimetic dermis.

Abstract: Provided are a method for preventing damage to the nuclear membrane of skin cell including administering an effective amount of amentoflavone to a subject and a method for anti-aging including administering an effective amount of amentoflavone to a subject. By controlling the expression of defective lamin A induced by UV radiation or controlling the expression of phosphorylated H2A histone family, member X (H2AX) induced by UV radiation, the disclosed method prevents nuclear membrane damage and thus prevents skin cell damage. Accordingly, a composition containing amentoflavone as an active ingredient may be used as a cosmetic composition or a pharmaceutical composition.
