Moisturizing and circulation promoting essence and preparation method thereof

Technical Field

The invention relates to the field of cosmetics, and particularly relates to a moisturizing and circulation-promoting essence and a preparation method thereof

Background

The skin is a main reservoir in human body, and has water content of 18-20% of body weight, water is one of important shaping substances in horny layer of epidermis, and water content of 10-20% in horny layer. The degree of stratum corneum water content directly affects the skin condition: the water content is 10-20%, and the skin is soft, moist, smooth and elastic; the water content is less than 10%, the skin is dry and rough, the content is continuously reduced, and the skin can be chapped. And the stratum corneum in the epidermis is the first barrier of the human body and mainly plays the roles of keeping skin moisture, preventing water in the body from evaporating and resisting external foreign matters from invading the body. And can prevent invasion of toxic substances, microorganisms and the like and damage of ultraviolet radiation. The stratum corneum holds water by intercellular lipids. Wherein the epidermis layer is the outermost layer structure of the skin and is the first barrier of the human body. The epidermis is divided into stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum and stratum basale. The moisture content of the skin is determined by measuring the water content of the stratum corneum. The horny layer is divided into corneocytes and intercellular substance, and the arrangement mode of the two substances is similar to that of a brick wall structure, so that a barrier is formed together, the stimulation of the outside to the skin is prevented, and the loss of skin moisture is slowed down. The basal layer contains aquaporin AQP-3, and can regulate the absorption of substances such as water, glycerol and the like by human skin.

The mechanisms of skin moisturizing and promoting circulation are commonly used: 1. absorbing the external moisture. Many of the moisturizers in cosmetics have water absorption properties and are capable of adsorbing moisture in the air and also drawing moisture from deep layers of the skin to the top layers of the skin to maintain the moisture content on the surface of the skin. Such as polyols like glycerol. 2. Reduce the water evaporation of the skin. The oil and fat substances used in cosmetic can form a protective film on skin surface to slow down water evaporation in skin. Such as mineral oil, various animal and vegetable oils, etc. 3. Repairing stratum corneum cells, and improving water retention and moisture retention ability of skin. Such as ceramide, can repair intercellular matrix of skin stratum corneum, and improve water retention capability of stratum corneum. The vitamin C can promote the synthesis of collagen in the dermis and has the effects of moisturizing and removing wrinkles. The fruit acid can promote metabolism of epidermal cells of skin, promote repair of epidermal cell tissues and play a role in moisturizing. 4. Free water molecules are bound. Macromolecular substances such as hyaluronic acid and the like can form a net structure to combine free water molecules in the skin, so that the evaporation of skin moisture is slowed down.

The vitamin C can promote the synthesis of collagen in the skin, remove free radicals, adsorb the damage of ultraviolet rays to the skin and achieve the effects of resisting wrinkles and whitening; levorotatory vitamin C ("levorotatory C") is the only form of vitamin C that can be directly absorbed by the human skin. It has the functions of promoting collagen proliferation, repairing the damage of ultraviolet ray to skin, eliminating melanin, etc.

Sodium hyaluronate is an inherent component in the human body and is a kind of glucuronic acid. Is an important humectant in cosmetics and can absorb about 1000 times of water by weight. Compared with other moisturizing ingredients, the moisturizing effect of the moisturizing cream is less influenced by the relative humidity of the surrounding environment; can quickly replenish skin moisture, adjust the water-oil balance of the skin and make the skin delicate.

Bioglycan-1 is a biological polysaccharide in which a significant amount of fucose, commonly referred to as fucosan, is present in the molecule. Mainly exists in a plurality of brown algae such as Fucus vesiculosus, Ascophyllum nodosum, Undaria pinnatifida, seaweed, Himalayan Kjellman and kelp. A novel humectant, wrinkle removing agent, skin repairing agent and skin feeling regulator in cosmetic industry. It has long-acting moisturizing effect, and can moisten skin and relieve fine lines and wrinkles of skin; can moisturize, improve skin feel, relieve skin and bring soft, smooth and pleasant skin feel to the skin.

The active components of the ginkgo leaf extract are terpene components, including bilobalide and bilobalide, and the ginkgo flavone-glycoside components have strong antioxidant and free radical scavenging capacity and can achieve the effects of promoting circulation, resisting oxidation and resisting aging. Can promote the circulation of brain and body limbs, and regulate blood vessel tension and elasticity. The blood circulation can be more effective. It can be applied to skin to promote blood circulation.

The skin care effect of the D-panthenol is represented by a deeply penetrating humectant, the panthenol has a small molecular weight, can effectively infiltrate and penetrate into a cuticle, has a strong moisturizing effect, effectively improves skin roughness, enables the skin to be soft and not sticky, can stimulate the growth of epithelial cells, promotes wound healing, and has an anti-inflammatory effect.

The tea extract is rich in tea polyphenols, and has effects of resisting oxidation, scavenging free radicals, promoting new skin circulation, etc. Has anti-allergic and anti-inflammatory effects, can effectively inhibit the activity of hyaluronidase, slow down the decomposition of hyaluronic acid in skin, and has the effect of assisting in moisturizing. Meanwhile, the tea extract is also an excellent natural antioxidant, has a synergistic effect with vitamin C, vitamin E, carotenoid and the like, and has an antioxidant effect on the skin.

The trehalose has small molecular weight, is easy to be absorbed by the skin, enters the cells to play the unique water substitution stress factor effect and the function of protecting cell membranes, and improves the anti-drying and anti-freezing capability of the cells, thereby improving the environmental adaptation capability of the skin.
