Method for improving skin aging and skin elasticity by applying stem cells

Abstract

The invention discloses a method for improving skin aging and skin elasticity by applying stem cells. The method for improving the skin aging and the skin elasticity by applying the stem cells comprises two steps, including a step of carrying out stem cell extraction and a step of carrying out stem cell retransmission; and the stem cells are selected from a subject's autogenous fat stem cells. Themethod for improving the skin aging and the skin elasticity by applying the stem cells specifically comprises the following processes: extracting autogenous fat stem cells from a subject in a hospital, and transporting the extracted autogenous fat stem cells in refrigerated state to a cell preparation center by adopting cold-chain transportation; culturing the autogenous fat stem cells in a culture flask in a GMP laboratory so as to perform passage and amplification on the subject's autogenous fat stem cells in the GMP laboratory for 15-30 days, and transporting the amplified autogenous fat stem cells in refrigerated state to the hospital by adopting cold-chain transportation; and then, retransmitting the amplified autogenous fat stem cells into the body of the subject in the hospital byadopting intravenous injection. The stem cells are capable of removing fat from the forehead so as to tighten the eyebrows, reduce wrinkles, reduce fine lines, eliminate black spots and reduce nasolabial wrinkles.

Description

technical field [0001] The invention belongs to the technical field of cosmetic methods, and in particular relates to a method for improving skin aging and improving skin elasticity by applying stem cells. Background technique [0002] Skin aging refers to the aging damage of skin function, which makes the skin's ability to protect the body and adjustment ability decline. As a result, the skin cannot adapt to changes in the internal and external environment, and the overall appearance of the skin changes in color, luster, shape, and texture. Skin aging is divided into endogenous aging and exogenous aging. Endogenous aging refers to the natural aging of the skin with age, manifested as skin whitening, fine wrinkles, decreased elasticity, and sagging skin. The main cause of exogenous aging is photoaging caused by sun exposure, which is manifested as wrinkles, sagging skin, rough, yellowish or sallow skin discoloration, telangiectasia, and pigmented spots formation. The most ...

Problems solved by technology

2. Due to the slowing down of skin metabolism, the moisturizing factor in the dermis decreases, causing the function of elastic fibers and collagen fibers in the dermis to decrease, resulting in skin tension and elasticity weakening, making the skin prone to wrinkles

3. The skin of the face is thinner than the skin of other parts of the body. Due to the nutritional barrier of the skin, the storage of subcutaneous fat gradually decreases, the cells and fibrous tissues are malnourished, and the performance declines.

3. Excessive exposure to sunlight leads to excessive oxidation of the skin and causes skin aging

2. Dryness and peeling: dead skin cells block the pores, affect the secretion of water and oil, and make the skin lack a layer of natural moisturizing film to protect and moisten the skin, resulting in dry skin

4. Melanin deposition affects metabolism: These dead skin cells that block pores will affect cell metabolism, so that melanocytes cannot diffuse and excrete, resulting in pigmentation, dark spots and freckles

Skin aging is an irreversible process. There is currently no way to reverse the aging process, but it can be alleviated to a certain extent. Generally speaking, women’s skin is in the best condition in their life when they are around 25 years old, but from then on it will be Gradually worsening, signs of aging visible to the naked eye will appear around the age of 30. The internal manifestations of skin aging: 1. The content of natural moisturizing factors decreases, and the water content decreases by 25% to 35% when it is younger. The stratum corneum becomes thicker and the skin is dry. luster

2. The number of sweat glands decreases, sweat nourishment is insufficient, heat dissipation becomes poor, and heat stroke is easy

3. Collagen is reduced by more than 50%, elastic fibers and reticular fibers are lost, lack of elasticity, and skin is loose

2. More acne and enlarged pores

2. True wrinkles appear on the basal layer of the skin. They often appear when the skin does not supply moisture for a long time, and the skin is exposed to the sun without too much maintenance. The lack of skin nutrition leads to the loss of collagen and tissue breakage at the base of the skin.

Adult stem cells are essential for replenishing cells that are purged from tissues, but their capacity gradually declines with age, stem cell depletion, and accumulation of senescent cells

[0008] Several methods of delaying aging in the prior art are: 1. Internal nourishment and external nourishment: Supplement skin nutrition through food supplements. Although this method can make people look better in the short term, it still cannot reverse the process of cell apoptosis in the long term

2. Reasonable exercise: Reasonable exercise can help the body cells to maintain a healthy state and delay aging, but most people seriously lack correct and reasonable exercise

3. Modification and concealment: surface modification through cosmetics can only improve the external visual effect, but cannot improve the cell condition of the skin

4. Instruments and equipment: Stimulate the potential of cells in the skin in advance through instruments and equipment, which can improve the skin condition in the short term, but may accelerate the process of cell apoptosis
