[0011] In order to solve the other technical problems mentioned above, the present invention provides a method for improving swelling characterized by applying the above-mentioned cosmetic composition for improving swelling to human skin. Effects of the invention

[0012] As such, a cosmetic composition for improving swelling according to the present invention, characterized by including pumpkin extract, pineapple extract, hydrolyzed collagen, hydrolyzed lopitheca extract, and sodium heparin as active ingredients, has an effect of improving swelling of the skin, such as the face. Specific details for implementing the invention

[0013] The present invention will be described in detail below.

[0014] The present invention provides a cosmetic composition for improving swelling characterized by including pumpkin extract, pineapple extract, hydrolyzed collagen, hydrolyzed lopitheca extract, and sodium heparin as active ingredients.

[0015] The pumpkin used in this invention is rich in vitamin A and potassium and can be cooked and eaten in various ways. In Korea, it is eaten by making pumpkin porridge or adding it to rice cakes, and it is also consumed to reduce swelling during postpartum recovery. In the West, it is used to make pies. Pumpkin seeds are a widely enjoyed snack and are also a source of protein and iron. They contain a large amount of alpha-carotene, which is effective for anticancer effects, and are rich in protein and dietary fiber, making them beneficial for diabetes and weight loss. They also help excrete sodium, which is a cause of high blood pressure, from the body, and due to their high fiber content, they are effective in preventing constipation as well as colon cancer.

[0016] The pineapple used in this invention, known as *Pineapple* (English: pineapple, scientific name: Ananas comosus) or *Bongrisu*, is a perennial plant of the Pineapple family native to northern tropical South America. The etymology of *pineapple* originates from the English term 'pineapple,' which referred to pine cones before the 1690s, due to the fruit's resemblance to a pine cone. Currently, to prevent confusion with pineapples, the name for pine cones has been changed to 'pine cone' or 'conifer cone.'[1] Since 'apple' is a common noun meaning round fruit or berry in addition to meaning apple, *pineapple* means a fruit or berry resembling a pine cone. The fruit is eaten raw or processed into canned goods. Pineapple juice, salads, snacks, and various desserts are foods enjoyed by many people. In South Korea, thanks to the development of greenhouse horticulture, test cultivation was successfully achieved on Jeju Island in 1964, and it is now cultivated in the central region as well as in Gangwon Province. There are over 100 varieties, including strains with thorns on the leaf margins and those without.

[0017] The hydrolyzed collagen used in this invention is a collagen consisting of short amino acid chains broken down through the hydrolysis of collagen, also known as collagen peptide. Contrary to common belief, hydrolyzed collagen does not function as an anti-aging ingredient but rather acts as a moisturizer that helps supply moisture to the skin. Moisturizers help create moist and smooth skin by attracting and retaining moisture. It is particularly effective when paired with emulsifiers that help maintain moisture within the skin. This collagen is naturally produced in the body and, along with elastin, supports the skin structure to help maintain youthful and elastic skin. As we age, the rate of collagen and elastin production in our bodies slows down. These substances can be damaged, mostly due to exposure to ultraviolet rays and accumulated environmental factors, leading to skin sagging.

[0018] Because the above hydrolyzed collagen molecules are large, they cannot penetrate the skin and affect its structure. For this reason, anti-aging products use ingredients that stimulate collagen, such as retinol and vitamin C.

[0019] The hydrolyzed rhodophysia extract used in this invention is a type of red algae that, like other types used in skincare products, is a good source of antioxidants and helps maintain skin health by improving hydration. Antioxidants found in many algae, including this red algae, help counteract damage-causing UVB rays. Additionally, red algae are a rich source of carrageenan, which acts as a natural thickener and gel formulation in cosmetics. The carrageenan in red algae helps deliver other ingredients across the epidermal layer of the skin. Furthermore, red algae are a source of plant cholesterol, and this fatty acid compound is beneficial to the skin.

[0020] According to one embodiment of the present invention, the cosmetic composition is characterized by comprising 50 to 100 parts by weight of pineapple extract, 20 to 40 parts by weight of hydrolyzed collagen, 20 to 40 parts by weight of hydrolyzed lopithecus extract, and 20 to 40 parts by weight of sodium heparin, based on 100 parts by weight of pumpkin extract.

[0021] According to one embodiment of the present invention, the cosmetic composition is characterized by additionally including hibiscus extract in an amount of 10 to 20 parts by weight per 100 parts by weight of pumpkin extract.

[0022] The aforementioned hibiscus is a plant belonging to the genus Hibiscus of the family Malvaceae in the order Malvales of dicotyledonous plants, characterized by its red petals. Anthocyanin, the component responsible for the hibiscus's red color, is known as a powerful antioxidant that aids in smooth metabolism and the elimination of waste products. In addition to this, hibiscus contains various beneficial active ingredients and is widely used as a key component in cosmetics, food and beverages, and food products. In particular, hydroxycitric acid (HCA) contained in hibiscus is a substance that reduces fat activity; having been recognized by the Ministry of Food and Drug Safety as a functional ingredient for weight loss, it is gaining popularity as a raw material for inner beauty foods and health functional foods among not only young adults but also middle-aged and older adults.

[0023] According to one embodiment of the present invention, the cosmetic composition is characterized by additionally including a Job's tears extract in an amount of 10 to 20 parts by weight per 100 parts by weight of pumpkin extract.

[0024] The aforementioned Job's tears are used for both edible and medicinal purposes. Although research on the immune-boosting properties of Job's tears is limited, bioactive substances identified in many existing studies include coixenolide and free fatty acids, which are anticancer components; phytosterol derivatives, which are ovulation-inducing components; and glycans such as coixans A, B, and C, which are blood sugar-lowering components. Additionally, glucan and heteroglucans such as CA-1 and CA-2 are known as anti-complement active components, and glutinous protein, a trypsin inhibitor, has been isolated from rice husks. Furthermore, Job's tears are known to have anti-arterial strengthening effects, and α-amylase inhibitors have been isolated, indicating great potential as a functional food ingredient.

[0025] The term "extract" as used in the present invention includes the extract itself and all formulations of extracts that can be formed using the extract, such as an extract obtained by extraction treatment of the natural material, a diluted or concentrated extract, a dried product obtained by drying the extract, a modified or purified extract, or a mixture thereof.
