This invention provides recombinant humanized elastin, its preparation method, and its applications, relating to the field of bioengineering technology. Based on humanized elastin, this invention utilizes a combination design based on the functional domains of elastin to obtain recombinant humanized elastin, discovering novel bioactive functional fragments of humanized elastin. The recombinant humanized elastin of this invention integrates multiple elastin functional sites. Specifically, this recombinant humanized elastin exhibits significant effects in promoting cell proliferation and increasing the expression of collagen and elastin genes, demonstrating high safety and wide applicability in various scenarios, and providing a new active ingredient for anti-aging related products. Furthermore, the theoretical molecular weight of this recombinant humanized elastin is significantly smaller than that of natural full-length elastin, reducing obstacles for elastin to cross the skin barrier and exert its biological functions, thus exhibiting excellent biological efficacy.
