Description

Preparation method and application of repairing and anti-aging composition containing vitrine

Technical Field

The invention belongs to the field of daily cosmetics, and particularly relates to a preparation method and application of a repairing and anti-aging composition containing a vitreous color factor.

Background

The skin barrier is a protective structure on the surface of the skin, and consists of a sebum membrane, a cuticle, a microorganism layer and the like, and can prevent water loss, resist external stimulus and pathogen invasion and maintain the health and stability of the skin. The damage of the skin barrier means that the protective structure is damaged or weakened, so that the problems of dryness, sensitivity, red blood streak, acne, color spots and the like of the skin are caused.

There are many reasons for the damage to the skin barrier, such as excessive cleaning, exfoliating, the use of unsuitable skin care products, exposure to ultraviolet light or environmental pollution, etc. Repair of the skin barrier is typically accomplished by the following pathways: (1) stopping damaging the skin barrier, avoiding using skin care products with strong irritation or efficacy, and selecting mild and low-sensitivity products; (2) the sensitive and repair barrier is relieved, and a skin care product containing repair factors is used for constructing a moist repair environment for the skin; (3) strictly protects, avoids secondary injury, makes sun-proof work, reduces the outgoing time and avoids contacting with irritant substances.

Skin aging refers to the irreversible degradation process that occurs in the structure and function of the skin with age. There are many causes of skin aging, including endogenous and exogenous factors. Endogenous factors are mainly inheritance, hormones, cell aging and the like, and exogenous factors are mainly ultraviolet rays, oxidative pressure, environmental pollution and the like. The skin aging is characterized by the following aspects: skin thinning, fragility, dryness, sagging, wrinkles, etc.; the skin has reduced barrier function, moisturizing ability, repairing ability, immunity ability, etc.; pigmentation of the skin, spots, red blood filaments, etc. are increased. Reduced sensation of skin, temperature, pain, etc

Hydroxypropyl tetrahydropyranol, also known as vitriol, is a xylose derivative with anti-aging activity, and can promote synthesis of glycosaminoglycan and collagen in skin, enhance elasticity and compactness of skin, and improve texture and color of skin. The vitrine is extracted from beech's xylose or synthesized artificially, and is a patent ingredient and is mainly used in cosmetics at present. The vitreous color is suitable for dry, sensitive, mature muscle and skin with water deficiency at the bottom of muscle, and can be used together with other anti-aging components such as A acid and peptide to achieve better effect.

Tetrahydropyrimidine carboxylic acid, also known as Ectoin, is a natural cosmetic ingredient, has multiple effects of moisturizing, resisting oxidation, inflammation, resisting ultraviolet rays, and the like, and can protect and repair skin and delay skin aging. Ectoin is found from a number of bacteria that can survive in extreme environments and can help the bacteria resist stress such as high temperature, dryness, salinity, etc. Ectoin can form a stable complex with moisture in the skin, increase the moisture content and elasticity of the skin, and reduce dryness and sagging of the skin. Ectoin also can inhibit free radical generation, prevent skin from being damaged by ultraviolet and environmental pollution, and improve skin luster and uniformity. Ectoin is a mild and safe ingredient suitable for various skin conditions, especially sensitive skin.

In addition to various effective components for repairing skin barrier, various chemically synthesized auxiliary materials are added into the existing cosmetics for repairing skin barrier. Although these auxiliary materials have effects on the shelf life, stability and the like of the whole product, the chemically synthesized auxiliary materials have irritation and poor overall use feeling for users with damaged skin barriers. Therefore, there is a need to develop a skin barrier cosmetic with little or no chemical synthesis adjuvants.
