Summary: Can eating bird’s nest whiten your skin? When eating bird's nest, it can increase the metabolic capacity of skin cells through internal nourishment, and promote the replacement and repair of epidermal cells. External regulation plus internal nourishment is the basis for whitening. The key to skin whitening: cell repair power! The rich collagen in bird's nest can effectively inhibit the activity of tyrosinase and reduce the production of melanin. Bird's nest is an antioxidant food with detoxification effect. Long-term consumption can achieve whitening and delay aging. Why does skin darken?

The number one culprit of skin darkening is ultraviolet rays. Most melanin is accumulated over time, because the damage caused by ultraviolet radiation will not be easily exposed, but it will definitely accumulate deep in the skin, and once damaged, it is difficult to eliminate.

Many women think that sun protection is to prevent tanning, but this is not necessarily the case. The most lethal thing in the sun is long-wave ultraviolet rays! Long-wave ultraviolet rays - UVA with a wavelength range of 320 to 400nm. Most UVA can penetrate our dermis and reach the middle of the dermis to destroy the collagen and elastic fibers in the skin, making the skin become... Sagging and wrinkles appear. Therefore, while applying sunscreen obediently, it is safer to wear hard sunscreen, such as parasols, sunglasses, hats, etc.

Why is it that as we age, our skin does not repair as fast as before, and even if we cover it for a whole winter, it will never come back? We must first understand the self-repair mechanism of epidermal cells.

From a dermatological point of view, the normal metabolism of the skin should be about 28 days. In other words, it takes approximately 28 days for an epidermal cell to gradually replace itself from the lowest layer of the skin to the epidermal layer. At the same time, as age increases, the metabolic cycle of epidermal cells will become longer and longer. It takes about 28 days for normal epidermal cells to grow from new to falling off.

Will eating bird's nest really turn white?

From the age of twenty-five, the metabolic cycle of skin cells begins to slow down significantly. After the age of thirty, epidermal cell renewal becomes slower.

As the repair ability of skin cells becomes worse and worse, it will take longer and longer for tanned skin to return to whiteness. If the tanning is severe, the "color number" of the skin will become darker and darker. If your self-resilience cannot keep up, it will be difficult to "come back in vain".

Therefore, no matter how expensive sunscreen and skin care products are, the metabolic cycle of epidermal cells cannot be changed by skin care products. Internal nourishment can enhance the metabolism of skin cells and promote the replacement and repair of epidermal cells. , external regulation and internal nourishment are the basis for whitening.

Why can eating bird's nest make people whiter?

The key to skin whitening: cell repair power!

Is bird’s nest useful? Research by German scholars has shown that the rich collagen in bird's nest can effectively inhibit the activity of tyrosinase and reduce the production of melanin. Not only can it provide sun protection, but it can also replenish the nutrients needed by all layers of the skin, enhance the activity of collagen in the skin, whiten and moisturize the skin, and delay aging.

Anti-aging medical research also proves that bird's nest is an antioxidant food with detoxification effect. Long-term consumption can achieve whitening and delay aging.

Whitening effects and effects of bird's nest

Research has found that bird's nest contains a very important polypeptide - epidermal growth factor (EGF). This substance is present in most human fluids, especially in milk and semen. It is mainly composed of the submandibular gland and duodenum in the human body. It has many important physiological functions, such as inhibiting gastric acid secretion, protecting the duodenum, etc., so bird's nest has excellent beauty and skin care effects.

EGF epidermal growth factor is a small peptide composed of 53 amino acid residues. As a multifunctional growth factor, it has a strong mitogenic effect on many types of tissue cells in vitro and in vivo. EGF should also respond to specific receptor binding on epithelial cells and promote receptor dimerization and phosphorylation at cytoplasmic sites. Activating receptors bind at least 5 proteins with different signal sequences to signal transduce and modulate protein composition at the translation level. In addition, EGF can increase the activity of DNA topoisomerase in cells, and also promote the expression of some genes related to proliferation, such as Myc, Fos, etc.

1. Efficient correction

Active growth factors bind to specific receptors on the cell membrane around the wound, thereby activating proteases, accelerating protein composition, promoting the growth of fibroblasts, and promoting skin And mucosal wound healing and scar shrinkage and deformity feed skin hyperplasia, quickly and effectively correct trauma. It is applied to various kinds of damage to the skin, removes acne, acne, skin blemishes, redness, and other acidic applications that cause skin burns, and has excellent curative effect in repairing skin damage after grinding. EGF can promote the proliferation and decomposition of epidermal cells, the aging and death of cells, causing the skin to be immediately repaired. It can be used for skin problems such as discoloration, redness, telangiectasia and other undesirable skin disorders to improve skin fineness, roughness, scars and other unfavorable conditions. Leaves skin lubricated and lubricated.

The epidermal growth factor (EGF) in bird's nest acid can stimulate the division and proliferation of various cells, promote cell differentiation, and can repair skin cells burned by the sun. It can also affect the growth and development of human skin. Delicates and ages skin, making skin smooth and elastic.

2. Reduce wrinkles

Promote the growth and proliferation of fibroblasts and epidermal cells, promote metabolism, elastic fiber cell development, enhance function, activate the regeneration of aging cells, and accelerate cell metabolism. The new replaces the old. Renewes rapidly aging skin and corrects the rupture of epidermal and dermal fibroblasts, thus eliminating wrinkles. EGF active factor promotes fibroblast dermis, collagen fibers and elastic fibers to repair aging; synthesize and secrete more collagen, hyaluronic acid and other macromolecules; improve skin microcirculation, provide a good nutritional environment, and maintain a certain amount of skin Fat, restore skin elasticity, make it even and firm.

3. Anti-aging

EGF can promote the growth and division of skin epithelial cells, keratinocytes, fibroblasts, etc., accelerate the activity of epidermal cells, replace old ones with new ones, and strengthen them. Cells maintain perfect quality and quantity, making skin wrinkles disappear, soft, smooth, healthy and beautiful. Promote cell metabolism (anti-aging): EGF can promote cell proliferation and decomposition. EGF can reverse the decomposition of mature cells into "stem cell islands" and inhibit the expression of aging genes. EGF completely changes the composition of skin cells, reduces the average age of skin cells, and makes the skin smooth and beautiful.

4. Lighten spots

If the skin and skin pigment are calm and darker, EGF can promote new cells to replace aging cells, reduce the content of melanin and colored cells in the skin; and can increase the blood content of the skin. Flow, improve skin microcirculation, provide a good environment for nutrient epidermal cells, prevent metabolite deposition, effectively improve skin color, darken and calm, and make all kinds of skin uniform and beautiful. The skin pigmentation is calmer and the skin pigmentation is deeper, which promotes cell proliferation, promotes the distribution of subcutaneous capillaries, promotes blood circulation, and accelerates the discharge of melanin from the skin. The benefits of eating bird's nest for women are effective reduction of melanin deposition, giving full play to the whitening effect and role of bird's nest. .

5. Moisturizing and hydrating

Improve skin microcirculation (lubrication) and promote the composition and excretion of hyaluronic acid (moisture): EGF can promote extracellular hyaluronic acid, glycoprotein and The composition secreted by macromolecules enhances the hydrophilicity of the skin and maintains skin moisture. EGF can improve skin microcirculation, make blood and blood flow smoothly, avoid the accumulation of metabolites, and nourish the skin. Maintain moisture in the dermis, restore skin health, increase the moisturizing capacity of the stratum corneum, moisturize and release the skin. EGF can improve skin microcirculation, provide a good nutritional environment, maintain a certain amount of skin fat, restore skin elasticity, and make it even.

Bird's nest, which contains a large amount of epidermal growth factor, is a good product for beauty and skin care. It is stronger than many cosmetics, and many celebrities and politicians use bird's nest as a beauty tonic.

The water-soluble protein in bird's nests compensates for the loss of collagen in the human body due to age, allowing the skin to maintain moisture and elasticity. Moreover, bird's nest is nourishing without causing internal heat, and can also relieve heat and reduce internal heat and remove dryness in the lungs.
