The prepared freeze-dried powder product is stable in property, so that the biological activity of the mesenchymal stem cell factor freeze-dried powder is achieved for a long time.

Description

Technical field [0001] The invention belongs to the technical field of skin repair, and specifically relates to a mesenchymal stem cell factor and a preparation method and application thereof. Background technique [0002] The skin is the largest organ of the human body and covers the surface of the human body. It has the functions of protection, sensation, and regulation of body temperature. Its structure is from top to bottom, followed by epidermis, dermis and hypodermis. As people grow older, the signs of skin aging will gradually appear. The causes of skin aging can be divided into internal and external causes. [0003] Intrinsic aging refers to the natural aging process of the body, including the gradual decrease of keratinous stem cells as we age, resulting in basal cell disorders, reduced hyaluronic acid, and loss of moisturizing factors; decreased secretion of hormones (such as sebaceous glands) slows down the overall The metabolism of the skin ultimately makes the skin la...
