Description

Composition for improving scalp and skin health with a mixed extract culture solution of Rosa rugosa, matricaria flower, lemon balm leaf, and citron The present invention relates to a composition for improving scalp and skin health comprising a culture solution of mixed extracts of Rosa rugosa, Matricaria flowers, lemon balm leaves, and Yuzu. The scalp and hair are contaminated by various sebum, pollutants, and lack of care, and as a result of this process, itching increases and hair shine gradually decreases. Conventionally, the composition of commonly used shampoos consists of a shampoo base component composed of anionic surfactants, pH adjusters, thickeners, preservatives, and water, and optionally includes additives such as moisturizers and fragrances. Conventional shampoo compositions having such a composition have high viscosity. However, while the above-mentioned conventional shampoo compositions improve hygiene and shine, they contain a large amount of anionic surfactants among the components of the cleansing agent that are irritating to the scalp and hair, and are particularly irritating to people with sensitive scalps and hair, causing damage to the scalp and hair, wrinkles on the skin, increased scalp itching, hair loss, and scalp pruritus. Meanwhile, the skin is the outermost part of the body, composed of a three-layer structure of the epidermis, dermis, and subcutaneous tissue. It serves as a physical barrier protecting the body from the external environment and performs major biological functions such as absorbing substances, regulating body temperature, and maintaining homeostasis. However, as we age, skin cells become damaged due to pollutants, ultraviolet rays, and stress, and impaired cell proliferation leads to wrinkles, loss of elasticity, and keratinization. The stratum corneum, the upper layer of the epidermis, performs the role of a skin barrier by controlling the movement of substances physically and chemically, and changes occurring in the skin barrier are a significant cause of dry skin. Filaggrin, a protein produced by keratinocytes, plays an important role in the formation and maintenance of the skin barrier. The stratum corneum is composed of intercellular connection structures; as a component of these structures, Claudin-1 is a protein involved in tight junctions that maintains adhesion between cells and contains a transmembrane domain, acting as a physical barrier that regulates the movement of water or ions between cells. Skin aging can be caused by the activation of reactive oxygen species due to ultraviolet rays, stress, disease states, environmental factors, injuries, and aging; if this condition intensifies, it destroys the body's antioxidant defense network, damages cells and tissues, and accelerates adult diseases and aging. In particular, the oxidation of proteins causes the breakdown of skin connective tissues such as collagen, hyaluronic acid, elastin, proteoglycans, and fibronectin, leading to severe excessive inflammatory responses and impairing skin elasticity. If this worsens, it can result in DNA mutations, the induction of cancer, and a decline in immune function. Therefore, in order to recover and maintain healthy skin, it is necessary to protect cell membranes by eliminating reactive oxygen species generated during the body's metabolic processes or those mediated by UV irradiation and inflammatory responses, and to proliferate cells by regenerating already damaged cells through active metabolism. Meanwhile, itching refers to a skin condition that causes an unpleasant urge to scratch, and it is a common symptom experienced not only by people with atopic dermatitis but also by those with skin conditions such as psoriasis and contact dermatitis, as well as those with sensitive skin. Atopy is a type of dermatitis that commonly occurs in areas where skin folds, such as the face, arms, and knees. While it primarily develops during infancy and early childhood, it tends to escalate into a chronic condition that continues to affect individuals into adulthood. Atopic skin diseases are eczematous conditions caused by various factors, including genetic, immunological, and environmental factors, as well as defects in the skin barrier. They are characterized by dry skin, red spots, itching, and inflammation. The most significant symptom of atopic dermatitis is itching; scratching irritates the skin, which intensifies the itching and exacerbates the condition. According to recent research, when the cause of itching is signaled to the brain, it passes through the central nervous system (CNS), and it has been revealed that the signal transmission processes of pain and itching within the CNS mutually inhibit each other. Therefore, when one feels itching, applying pain (e.g., scratching) relieves the itching. However, scratching when it itches leads to an increase in the substances that cause itching, resulting in a vicious cycle where one becomes even more sensitive to stimuli
