Studies have found that bird’s nest contains an essential peptide substance - Epidermal Growth Factor (EGF). This substance exists in most human body fluids, and the content is exceptionally high in breast milk and semen. In the human body, it is mainly synthesized by the submandibular and duodenal glands. It has many essential physiological functions, such as inhibiting gastric acid secretion and protecting the duodenum.
Epidermal growth factor, also known as EGF, is a small peptide composed of 53 amino acid residues. It is a multifunctional growth factor with a substantial mitogenic effect on various tissue cells in vivo and in vitro. EGF binds to specific receptors in response to surface cells, promotes receptor dimerization, and phosphorylates cytoplasmic sites. The activated receptor can bind to at least five proteins with different signal sequences, conduct signal transduction, and regulate protein synthesis at the translation level. In addition, EGF can increase the activity of DNA topoisomerase in cells and promote the expression of some genes related to proliferation, such as MYC and FOS. In terms of beauty: EGF's performance are:
1. Efficient repair
Each growth factor actively binds to specific receptors on the cell membrane near the wound, thereby activating proteases, accelerating protein synthesis, promoting the growth of fibroblasts, promoting skin and mucosal wound healing, and nourishing scar contraction and skin abnormalities. Efficiently repair wounds. It is applied to various damages of skin tissues, removes acne, minor defects after removing moles, peeling, redness, etc. The remarkable effect of repair epidermal damage and skin burns after usage of fruit acid. EGF can promote the proliferation and differentiation of epidermal cells so that aging and dead cells can be supplemented in time so that the damaged epidermis can be repaired immediately. It can adjust various harmful skin types such as peeling, redness, telangiectasia and improve thin skin, roughness, scars, and other undesirable conditions that can restore smoothness to the skin.
2. Eliminate wrinkles
Promote the metabolism, proliferation, and growth of fibroblasts and epidermal cells, promote the development of elastic fiber cells, enhance their functions, activate the regeneration of aging cells, accelerate cell metabolism and renewal, and rapidly metabolize aging keratin, and repair broken superficial epidermal fibroblasts, Thereby eliminating wrinkles. Promote the proliferation of fibroblasts in the dermis through active factors such as EGF, repair aging collagen fibers and elastic fibers; synthesize and secrete more macromolecules such as collagen and hyaluronic acid; improve skin microcirculation and provide a good nutritional environment, maintain a certain amount of skin fat, restore skin elasticity, make it even and firm, and reduce wrinkles.
EGF can promote the growth and division of epithelial cells, keratinocytes, fibroblasts, and other cells in the epidermal tissue, speed up the metabolism, and enhance the activity of epidermal cells so that the cells can maintain the perfect quality and quantity, make the skin wrinkles disappear, and show tightness. Solid, tender, smooth, and elastic, healthy beauty. Promote cell metabolism (anti-aging): EGF can promote cell proliferation and differentiation. EGF can reverse-differentiate mature cells to form "stem cell islands" while suppressing the expression of aging genes. EGF fundamentally changes the composition of skin cells, lowers the average age of skin cells, and leaves skin smooth and beautiful.
4. Fade spots
For darker skin and various types of skin pigmentation, EGF can replace senescent cells by promoting new cells to reduce the content of melanin and colored cells in the skin; and can increase skin blood flow, improve skin microcirculation, and are epidermal cells. Provide an excellent nutritional environment, prevent the accumulation of metabolites, effectively improve the skin color, and make the darker complexion and all kinds of pigmented skin white and perfect, even, and beautiful. For darker skin and various types of skin pigmentation, it speeds up cell proliferation, promotes the distribution of subcutaneous capillary network, promotes blood circulation, accelerates the discharge of skin melanin, and effectively reduces the deposition of melanin, plays a role in whitening and lightening.
5. Moisturizing and hydrating
Improve skin microcirculation (smooth and clean), promote the synthesis and secretion of hyaluronic acid (moisturizing): EGF can promote the synthesis and secretion of extracellular hyaluronic acid, glycoprotein, and other macromolecules, enhance the hydrophilicity of the skin, and maintain moisture in the skin. EGF can improve the skin's microcirculation, make the qi and blood unblocked, prevent the accumulation of metabolites, and make the skin rich in nutrition. Maintain the moisture in the dermis; the skin is restored to health. The moisture retention capacity of the stratum corneum in the epidermis is enhanced so that the skin is moisturized and vitalized. EGF can improve skin microcirculation, provide an excellent nutritional environment, maintain a certain amount of skin fat, restore skin elasticity, make it even and firm, and reduce wrinkles.
