Abstract

The invention discloses an application of a transdermal peptide modified pueraria thomsonii exosome nano preparation in preparation of an anti-skin aging product. The pueraria thomsonii exosome nano preparation modified by the transdermal peptide can effectively penetrate through the cuticle of the skin and is efficiently taken by skin cells such as skin fibroblasts, so that the obvious function of resisting skin (cell) aging is exerted, and a new strategy is provided for skin aging resistance; The transdermal peptide modified pueraria thomsonii exosome can be used as a novel skin anti-aging beauty product which is efficient, safe and convenient to prepare, can also be applied to aging resistance of other cells and tissues, and is used for delaying aging and function decline of body tissues and organs; therefore, great market development prospects are realized in the fields of medical products and beauty cosmetics.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to the application of kudzu exosome nano-preparation modified by transdermal peptides in anti-aging skin. Background technique [0002] Aging is an inevitable law of any biological life process. With the increasingly prominent problem of population aging in the world, the field of anti-aging has become the focus of global attention. Old cells in human organs die gradually, and new cells are no longer produced. The dead old cells are decomposed by enzymes, and then absorbed by new cells to supply the nutrients needed for the growth of new cells, and cannot promote the continued division of old cells to produce more new cells. If things go on like this, new cells of human organs will no longer be produced, while the original old cells will continue to die. Organ function continues to decline until it fails and dies. Therefore, effective protection against organ aging c...
