Abstract

The invention discloses application of a hylocereus undatus stem extract in skin care products, and particularly relates to application of the hylocereus undatus stem extract in preparation of the skin care products with the effects of tightening skin and / or improving skin elasticity and / or moisturizing and / or resisting external stimulation and / or relieving and / or repairing. The hylocereus undatus stem extract is prepared by adopting a compsite enzymolysis and flash extraction combined technology, is high in total sugar content and good in stability, can remarkably reduce skin irritation reaction caused by lactic acid, and has the effects of tightening skin, moisturizing, resisting external irritation, relieving and repairing when being applied to the skin care products.

Description

technical field [0001] The invention belongs to the field of skin care products, and in particular relates to a skin care application of an extract from the stem of Tianchi. Background technique [0002] With the development of science and technology, the pollution of air and environmental food, and the use of cosmetics, the skin's resistance to foreign substances is getting worse and worse, and skin irritation and allergies are more and more frequent. Common symptoms of skin allergies are redness, itching, pain, and may also be accompanied by symptoms such as swelling, dry scales, and broken skin. In view of this, it is of practical significance to develop cosmetics with multiple functions such as soothing, repairing, and resisting irritation. [0003] The stem of Liangtianchi is the fleshy stem of the herbaceous plant of the genus Liangtianchi in the cactus family. It is rich in polysaccharides, sterols, flavonoids, essential mineral elements and vitamins and other biolog...
