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.
