Description

Skin-tendering anti-wrinkle bifidobacterium longum SF-B-60 fermentation product and preparation method and application thereof
Technical Field
The invention relates to the technical field of microorganisms, in particular to a bifidobacterium longum SF-B-60 fermented product capable of tendering skin and resisting wrinkle, and a preparation method and application thereof.
Background
Skin is the largest organ of human body, and damage to skin can be caused by various factors such as sun exposure, air pollution, electronic product radiation, living habit and the like, so that elastic fibers of the skin are damaged. Collagen and spandex in the skin gradually decrease, and at the same time, as the age increases, the self-repair mechanism of the skin also decreases, and wrinkles gradually appear. Wrinkle formation is mainly due to internal causes, and somatic aging is the most fundamental cause of wrinkles. With the increase of age, the cell activity gradually decreases, the metabolic capacity decreases, the number of new cells increases to be lower than the aging speed of the cells, the hydration capacity of the aged cells decreases, the photoaging effect is enhanced, the skin water-tightness and the moisture retention are reduced, the weight-added fiber tissue is deteriorated, and the skin is dry and easy to form fine lines. In addition, skin aging is accompanied by deterioration of sweat gland system, insufficient sebum secretion, and increases skin damage and dryness, and causes wrinkles.
The anti-wrinkle skin care products on the market at present have uneven effects, and the common cosmetic active ingredient additives mainly comprise arbutin, nicotinamide, tretinoin, azelaic acid and the like, have single action mechanism and have toxic and side effects such as cytotoxicity, skin irritation and the like. From modern medical research, chinese herbal medicines contain abundant proteins and various amino acids, lipids, polysaccharides, pectin, vitamins, trace elements, organic acids, alkaloids, saponins and other nutrient substances, and if the deep research is carried out, the formula is precisely combined, the functional activity is enhanced, and the cell proliferation and metabolism can be better promoted, the skin microcirculation is improved, and the oxidation resistance of an organism is enhanced.
