- a method for evaluating water retention a method for detecting the degree of oxidation of proteins in the stratum corneum based on the transparency and water retention of the stratum corneum, and a method for inhibiting the oxidation of proteins in the stratum corneum, This document relates to a method for maintaining and improving transparency of a layer.
- the sebum on the skin surface is oxidized by free radicals and lipid peroxide is generated, which initiates protein oxidation.Once the lipid peroxide is generated, the oxidation proceeds in a chain. It is thought that it not only stimulates the skin surface but also penetrates deep into the stratum corneum and damages cells. Therefore, the properties of skin oxidized proteins, such as their abundance and distribution, are evaluated to understand the skin quality or skin condition.Then, the evaluation results are used to determine the policy of the skin care method and select cosmetics. It is expected that it can be used in some way. However, at present, although a vague relationship between oxidized proteins and skin damage is expected, it is not clear how corneal protein oxidation actually affects skin properties. Has not been elucidated. Disclosure of the invention
- oxidized proteins present in the skin can be used to improve skin quality, etc., it is expected to be extremely beneficial in terms of dermatology and cosmetics. It can also be a powerful tool for providing counseling services for advice such as the skin care method.
- the present inventor examined the effects of stratum corneum on skin properties.As the oxidation of stratum corneum progressed, the water retention and transparency of the stratum corneum were lost. I found something to go. It is expected that the water retentivity and transparency of the stratum corneum will be lost to some extent due to UV irradiation, drying, aging, etc. It is the first discovered fact that protein oxidation is involved, and elucidation of this fact is extremely significant from a dermatological and cosmetic point of view.
- the detection of stratum corneum oxidized protein is performed by specifically labeling the carboxylate group of the oxidized protein in the stratum corneum sample collected from the skin with fluorescence and detecting the light emitted therefrom.
- the fluorescent labeling of the oxidized protein with respect to the carbonyl group of the oxidized protein is preferably performed using a hydrazino group-containing fluorescent substance, such as fluorescein-5-thiosemicarbazide or Texas red hydrazide.
- the present invention provides a method for detecting the degree of oxidation of a protein in a stratum corneum, which is based on the transparency and the water retention of the stratum corneum.
- the present invention provides a method for maintaining and improving the transparency and Z or water retention of the stratum corneum by suppressing the oxidation of proteins in the stratum corneum.

- the present invention provides a method for evaluating the transparency and / or water retention of a horny layer using an oxidized protein in the horny layer as an index.
- the skin will look as if it is transparent, and will have a very aesthetically pleasing appearance.
- the skin with high “water retention” of the stratum corneum or skin has a fresh, moist and healthy state. Therefore, it is extremely important for cosmetology that the skin have transparency and water retention, and in general, the transparency and water retention of the stratum corneum and the skin are subjective aspects of beauty specialists such as beauty technicians.
- the tests were carried out by sensory tests that depended on the skin, optical inspections and moisture tests of skin samples that required complicated operations and expensive equipment and facilities.
- the present invention uses the oxidized protein in the stratum corneum as an index, and more specifically, detects the abundance and distribution state of the oxidized protein in the stratum corneum, thereby obtaining “transparency” of the stratum corneum and thus the skin. It is possible to check “water retention” by simpler and more objective means.
- the method for detecting corneal oxidized protein is not particularly limited, and various methods known in the art can be used.
- a stratum corneum oxidized protein described in JJ Thi eleet al. FEBS Letter, 1998 Feb 6, 422 (3), 403-406

- tissue or cell Typical examples of the body part or region from which the sample is derived include a facial color, forehead, back of hand, and trunk.
- Such a sample may be obtained by an invasive method such as so-called surgical means, but especially for the purpose of evaluating skin quality, for simplicity. It is preferably obtained from the skin by a non-invasive method.
- a non-invasive method tape stripping or abrasion method commonly used in the technical field can be used.
- Tape stripping is particularly preferred in the present invention because a two-dimensional state of the skin can be directly transferred to the adhesive tape by applying and peeling an adhesive tape piece to the skin surface layer. . If the horny layer of the tape is collected by tape stripping, and the oxidized protein is specifically fluorescently stained without cutting, the two-dimensional oxidized protein corresponding to the actual two-dimensional properties of the skin can be obtained. Information will be obtained.
- a preferred method of tape stripping is to first clean the surface layer of the skin with, for example, ethanol to remove sebum, dirt, etc., and cut a piece of adhesive tape cut to an appropriate size (for example, 5 x 5 cm) on the skin surface. This is done by applying light force on the tape, applying even force to the entire tape and pressing it flat, and then peeling off the adhesive tape with even force.
- the adhesive tape may be a commercially available cellophane tape or the like, and, for example, a Scotch Superstressing Mailing Tape (manufactured by 3M) can be used.
- the fluorescent substance that specifically fluorescently labels the carboxy group of the oxidized protein that can be used in the preferred embodiment of the present invention is a hydrazino group that can bind to the carbonyl group of the oxidized protein.
- fluorescent materials include fluorescein-15-thiosemicarbazide, Texas red hydrazide, and the like.

- An appropriate buffer for example, 100 mM MES-Na buffer ( ⁇ 5.5)
- biotin hydrazide For the specific fluorescent labeling of the oxidized protein, a combination of biotin hydrazide and fluorescently labeled avidin can be used. Since biotin hydrazide also has a hydrazino group, it can bind to the carbonyl group of proteins. In this case, biotin hydrazide is first bound to the oxidized protein, and then the fluorescently labeled avidin is bound to the biotin hydrazide via the biotin-avidin bond. As a result, the oxidized protein is fluorescently labeled. Piotin hydrazide is well known in the art, and for example, one manufactured and sold by Pierce can be used. As the fluorescent avidin, for example, fluorescein avidin can be used.
- the detection of an oxide protein can be specifically performed, for example, as follows.
- An appropriate buffer for example, 100 mM MES-Na buffer (pH 5.5)
- the plate is sufficiently washed with an appropriate physiological solution (eg, a phosphate buffered saline solution (PBS)), and reacted with fluorescent-labeled avidin at room temperature for several hours (eg, 1 hour);
- an appropriate physiological solution eg, a phosphate buffered saline solution (PBS)
- Specific fluorescent labeling of the oxidized protein can also be carried out by allowing dinitrile phenylhydrazine to act on and bind to the carbonyl group of the oxidized protein, and labeling the dinitrophenol portion with a fluorescent dye. Therefore, in a further preferred embodiment of the present invention, the dinitrate phenol portion of the dinitrate phenylhydrazine bonded to the carbonyl group of the oxidized protein can be detected by a fluorescent immunoassay or the like.
