Description

Technical Field

[0001] This invention relates to the field of skincare and cosmetic technology, and specifically to a skincare oil with skin barrier repair function and its preparation method. Background Technology

[0002] As a relatively new product, facial oils are convenient, easy to use, and highly effective. They allow the addition of concentrated serum ingredients or components that are unstable in lotion or emulsion systems. While there are many types of facial oils on the market, their quality varies greatly. However, very few products truly offer anti-wrinkle and skin barrier repair benefits; most only moisturize and their ingredients cannot be guaranteed to be natural and safe.

[0003] CN 114588096 A and CN 107441002 A both disclose formulas for essential oils, but these patents do not have the anti-wrinkle, firming, and repairing effects needed for various skin problems. Therefore, they cannot effectively meet the skin repair and safety needs of many special groups such as sensitive skin, damaged skin, hormone-induced facial dermatitis, micro-plastic surgery allergies, and pregnant women. In addition, the above patents use synthetic oils or mineral-derived oils and contain some ingredients that are prone to causing allergies, so the safety of the products cannot be guaranteed.

[0004] Therefore, developing a safe, widely applicable, and skin barrier-repairing essential oil is of great practical significance. Summary of the Invention

[0005] Due to the aforementioned deficiencies in existing technologies, this invention provides an essential oil that is safe, widely applicable, and capable of repairing the skin barrier, overcoming the shortcomings of existing essential oils that cannot repair the skin barrier, have questionable safety, and are poorly applicable.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A skincare oil with skin barrier repair properties, comprising base oil components and active ingredients;

[0008] The base oil components include macadamia seed oil and sunflower seed oil;

[0009] The active ingredients include squalane, Kalahari watermelon seed oil, sandalwood seed oil, frankincense resin gel, oat oil, coconut oil-caprylate / caprylate, and vitamin E.

[0010] The skincare oils mentioned above that repair the skin barrier are mostly formulated with natural plant ingredients, ensuring good safety and effectiveness. They are safe skincare oil formulas. Some ingredients (such as Kalahari watermelon seed oil) are derived from African plants, some (such as frankincense resin gel) from Greece, some (such as oat oil) from Finland in Northern Europe, and some from Sichuan, China. The purest raw materials are used to achieve optimal efficacy. Specifically:

[0011] 1) Frankincense resin gel is used as an anti-wrinkle, firming, repairing and soothing ingredient. It has an all-around anti-aging effect, making the skin regain its youth. It can promote the synthesis of youth protein KLOTHO (cloxoprotein) and youth protein FOXO, increase the density of elastic fibers in the dermis, and ensure that these fibers are evenly distributed. It enhances cell vitality, improves facial contours, and makes the skin younger, firmer and more elastic. At the same time, it has antibacterial and anti-inflammatory properties to promote skin healing and regeneration, and is also a natural antioxidant.

[0012] 2) Kalahari watermelon seed oil is rich in fatty acids, sterols, and vitamins, which are the skin's vital hydration source. It contains high levels of linoleic acid, oleic acid, palmitic acid, and stearic acid, as well as high levels of γ-tocopherol, effective β-sitosterol, campesterol, and squalene, which make the product have excellent moisturizing and hydrating properties, good skin absorption and penetration, and effective protection and repair of the skin barrier function. Kalahari watermelon seed oil has a significant improvement in the barrier function of defatted and non-defatted human skin explants.

[0013] 3) Sandalwood seed oil contains high levels of monounsaturated fatty acids, including simulinic acid, a large amount of tocotrienols, abundant lupeol and β-amyrin, which can effectively promote blood circulation and cell renewal, soothe inflammation, fight microorganisms, resist oxidation and aging, moisturize the skin, repair the skin barrier, and firm the skin.

[0014] 4) The addition of ultra-refreshing plant oil ingredients, characterized by low molecular weight and low viscosity, gives the product a very refreshing feel, accelerates absorption, and makes the entire product feel as light as water. It reduces the viscosity of cosmetic components, making the skin feel comfortable, light and non-greasy, and improving the good skin feel of the formula.

[0015] 5) It contains oat oil from the Arctic region of Northern Europe, which is rich in active ingredients such as linoleic acid, omega-6 fatty acids, vitamin E, antioxidants, oat alkaloids, and ceramides. It contains a large number of functional compounds, such as phospholipids and glycolipids, as well as natural antioxidants, such as vitamin E, tocotrienols, and vitamin E in the form of oat anthraquinones. These are unique compounds in oats and are suitable for problem skin and sensitive skin. They help maintain normal skin barrier function, prevent moisture loss, and reduce external irritation.

[0016] The aforementioned skincare oils with skin barrier repair properties utilize natural, effective, and safe plant-based formulas, addressing the cosmetics industry's over-reliance on harmful chemical and pharmaceutical ingredients. They also address the difficulty for individuals with sensitive or damaged skin to find suitable skincare products, fulfilling their need for rapid skin repair and maintenance. Furthermore, they address the issue of skin allergies following cosmetic procedures (such as laser freckle removal), where skincare products must be discontinued and daily medication is required to reduce swelling and allergies; skincare products containing this oil can replace certain pharmaceutical ingredients and surpass the efficacy, speed, and safety of typical pharmaceutical ingredients. Finally, they address the concerns of pregnant women regarding chemical ingredients and safety, allowing them to continue enjoying natural and effective skin repair and maintenance during pregnancy.
