Polypeptide composition for preventing and improving striae gravidarum

Abstract

The invention discloses a polypeptide composition for preventing and improving striae gravidarum. The composition contains one, two or three polypeptides of a polypeptide for promoting collagen synthesis and promoting epithelial regeneration, a polypeptide for supplementing fibronectin and a polypeptide for promoting elastin synthesis, and one or two polypeptides of a polypeptide for reducing inflammatory response and tightening the skin and a polypeptide for delaying skin aging and raising defensive power of the skin. The polypeptide composition of the invention is safe to human body, has noirritating or toxic or side effect, can repair epidermis, basilar membrane and dermis of the skin, diminish inflammation, promote growth of connective tissues and increase generation of collagen and elastin, and can be used for antenatal prevention and postnatal repair of striae gravidarum.

Description

technical field

[0001] The invention belongs to the technical field of biomedical polypeptide drugs and provides a polypeptide composition for preventing and improving stretch marks. Background technique

[0002] Stretch marks (striae gravidarum) are a type of atrophic striae, which occur during pregnancy and are mainly manifested as atrophic cord-like skin changes on the abdomen, chest, lower back, buttocks and thighs. The early symptoms are dark red or purple stripes of different widths and lengths, followed by depigmentation, atrophy, and finally a white or silver linear skin lesion after stabilization. The occurrence of stretch marks and its difficult-to-eliminate symptoms have caused great psychological burden and stress to patients, and greatly affected their quality of life.

[0003] At present, the cause and mechanism of stretch marks need to be further studied. It is generally accepted that the occurrence of stretch marks is the result of endocrine factors leading ...
