Description

Cosmetic composition for improving skin itching and atopy, cosmetics containing the same, and method for producing the same The present invention relates to a cosmetic composition for improving skin itching and atopic dermatitis, a cosmetic product containing the same, and a method for manufacturing the same. More specifically, the invention relates to a cosmetic composition for improving skin itching and atopic dermatitis that includes a eutectic mixture of glutamine and linoleic acid to increase the penetration of glutamine through the keratin and enhance the solubility of linoleic acid in water, thereby having improved effects on itching and atopic dermatitis, and having complex improved effects on promoting skin regeneration and alleviating inflammation, a cosmetic product containing the same, and a method for manufacturing the same. The skin is the largest tissue in the body and serves as the primary organ for protecting and contacting the body against the external environment and stimuli. It not only acts as the first line of defense against external substances and stimuli but also plays a crucial role in internal metabolism by regulating body temperature and fluid balance. Furthermore, as the first organ visible to the outside, the skin is a vital component in expressing external beauty. In modern society, this emphasis on external beauty is increasingly becoming as significant as the emphasis on health. This is because, with the rising elderly population, physical beauty has established itself as a criterion symbolizing youth and health; moreover, for the younger generation, this external beauty manifests as confidence and serves as a competitive edge that influences their professional performance. For these reasons, active efforts are being made in both academic and industrial fields to prevent skin damage and aging. Atopy is a type of dermatitis characterized by chronic, recurring skin eczema accompanied by severe itching. As one of the representative allergic diseases alongside asthma, allergic rhinitis, and chronic urticaria, atopy is known to result from the complex interplay of various factors, including genetic predisposition, environmental factors, immunological abnormalities, and defects in the skin's protective barrier; however, it remains difficult to definitively determine the exact cause of atopy. The most significant characteristics of atopy are severe itching and a highly sensitive reaction to external stimuli or allergens. Recently, as the environment becomes increasingly polluted, skin diseases of unknown cause, most notably known as atopic dermatitis, are becoming more common. These conditions typically begin in infancy or childhood and persist for a long time or recur as the child grows, manifesting as symptoms such as dry skin, eczema, dermatitis, erythema, and itching. While there are treatment methods for atopic dermatitis involving the use of moisturizers to provide adequate hydration to dry skin and reduce itching and inflammation, or the use of antihistamines or steroids in severe cases, long-term use of antihistamines or steroids can lead to tolerance or increase skin hypersensitivity, causing redness, swelling, and acne even with mild irritation. Additionally, prolonged use can lead to damage to the immune system. Various functional cosmetics are being released to prevent or alleviate the symptoms of atopic dermatitis and other skin diseases. However, conventional functional cosmetics have side effects that make the skin sensitive and dry, and because they are not efficiently absorbed into the skin, there have been problems in that skin-improving effects—such as alleviating atopic symptoms, moisturizing, antibacterial, and anti-inflammatory action—are not effectively manifested. Furthermore, exposure to external factors such as excessive sunlight or environmental pollution can induce skin damage and inflammatory reactions, including itching. It is known that such skin damage and inflammatory reactions exacerbate atopic dermatitis and not only pose aesthetic issues but also cause various skin problems, such as secondary pigmentation and itching, due to substances generated during the inflammatory process. Recently, consumer interest in the field of atopic dermatitis has been increasing to address issues like itching and aesthetic concerns. While various products for improving atopic dermatitis are being developed, actual consumer confidence in their efficacy remains low. Although various cosmetic compositions are being researched to resolve these problems, conventionally known cosmetic compositions have limited usage amounts due to side effects upon application or have minimal penetration into the skin, making it practically impossible to expect any improvement. Therefore, there is an urgent need to develop new cosmetic compositions that possess comprehensive improvement effects for atopic dermatitis while being free from side effects compared to existing compositions.
