External skin preparation composition

Abstract

To provide novel skin preparation compositions containing ingredients that can improve dark circles and bags under the eyes, since dark circles and bags under the eyes can result from a variety of causes, including poor circulation due to lack of sleep or fatigue, dark circles being caused by stagnant blood flow, while bags under the eyes are also caused by sagging skin due to aging, and when microcirculation is impaired due to stress such as fatigue, white blood cells and red blood cells migrating out of the blood vessels through the tight junctions that connect cells, leading to the development of dark circles and bags.SOLUTION: The present invention provides a novel external skin preparation composition that improves endothelial barrier function and prevents the development of dark circles and bags under the eyes by incorporating an extract of Hippophae rhamnoides leaves.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a topical skin composition containing an extract of sea buckthorn leaves. Here, the topical skin composition refers to skin care cosmetics such as face washes, lotions, creams, and packs, makeup cosmetics such as foundations, lipsticks, and mascaras, body care cosmetics such as body soaps, slimming agents, UV protection agents, bath additives, and antiperspirants, and fragrance cosmetics such as perfumes and colognes, and also includes legal cosmetics, quasi-drugs, and pharmaceuticals. [Background technology]

[0002] Dark circles and bags around the eyes are caused by a variety of factors, including poor circulation due to lack of sleep and fatigue, and are not desirable from a cosmetic standpoint.

[0003] Dark circles are caused by poor blood flow, while bags under the eyes are also caused by sagging skin due to aging. However, when abnormalities in microcirculation occur due to stress such as fatigue, white blood cells and red blood cells migrate out of the blood vessels from the tight junctions that connect cells, leading to the development of dark circles due to pigmentation and edema (bags under the eyes).

[0004] To promote blood flow, Patent Document 1 discloses a method for improving congestion and eliminating dark circles and dullness under the eyes using vitamin K. Patent Document 2 also discloses a method for eliminating sagging eye bags using cosmetics containing water-absorbent resins that contain polysaccharides as structural units.

[0006] Against this background, research into ingredients that improve dark circles and bags around the eyes has progressed, and topical skin preparations have been developed, but the effects have not necessarily been satisfactory. [Means for solving the problem]

[0007] The present invention has been made under the above circumstances, and provides a novel skin topical composition that improves endothelial barrier function and prevents the development of dark circles and bags around the eyes by incorporating an extract of sea buckthorn leaves.

[0008] The first aspect of the present invention is a skin external preparation composition characterized by containing an extract of sea buckthorn leaves.

[0009] Claim 2 of the present invention provides the composition for external use on skin according to claim 1, in which the extract of sea buckthorn leaves is 0.01 to 95.0% by mass. [Effects of the Invention]

[0010] The extract of sea buckthorn leaves of the present invention enhances endothelial barrier function and prevents red blood cell migration, which causes pigmentation, and leukocyte migration, which causes edema, and therefore, when incorporated into an external preparation composition, is effective in suppressing the occurrence of dark circles and bags around the eyes. [Brief explanation of the drawings]

[0011] [Figure 1] Figure 1 shows the effect of the sea buckthorn leaf extract of the present invention on improving endothelial barrier function. When monolayer cultures of human dermal microvascular endothelial cells were stressed with TNF-α, treatment with the commercially available sea buckthorn leaf extract showed an increase in TEER, indicating that tight junctions were sufficiently formed and barrier function was maintained. DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention is described in detail below. The origin of the sea buckthorn used in the present invention and the method for producing the sea buckthorn leaf extract are not particularly limited, but it is preferable to use sea buckthorn leaves harvested in Canada. It is essential that the extract contains triterpenoid acids, triterpene alcohols, phytosterols, unsaturated fatty acids, tocochromanol, aliphatic esters, aliphatic alcohols, and mineral components. This sea buckthorn leaf extract is available as a solution mixed with octyldodecyl myristate as a commercial raw material called "Eyeglorius" from GATTEFOSSE SAS, France.

[0013] The amount of sea buckthorn leaf extract of the present invention is 0.01 to 95.0% by mass, preferably 0.1 to 10.0% by mass, of the total amount of the topical skin composition prepared using the commercially available raw materials. When preparing a typical topical skin composition, if the amount is less than 0.01% by mass, the effect of suppressing the occurrence of dark circles and bags around the eyes by improving the endothelial barrier function is not achieved. Although it is conceivable to incorporate an extract in an amount exceeding 10.0% by mass up to 95.0% by mass, this is not preferred because the effect commensurate with the amount incorporated gradually saturates.

[0014] The effect of the topical skin preparation composition of the present invention is to prevent the occurrence of dark circles and bags under the eyes, leading to a youthful and healthy skin. Therefore, further effects can be expected by adding a moisturizing component or a component with a blood flow promoting effect to the topical skin preparation composition of the present invention. Such components include vitamin C and its derivatives, nicotinamide, hyaluronic acid, plant extracts, etc.
