tendon of beef tendon, trotters, chicken wings, chicken skin, fish skin and cartilage are all rich in collagen.
Collagen Beauty Secrets
Every time I eat out, someone will point to that plate of pig's trotters and politely say to the lady at the same table, "Girls can eat more and be beautiful." Because many people know that pig's trotters contain a substance called collagen, and collagen is the hottest new term for beauty nowadays. From cosmetics for external use, to oral capsules, and then to filling materials for plastic surgery, it can be seen everywhere. What is collagen? What kind of beauty secrets does it have?
1 Collagen loss and aging
Collagen is a kind of polymer protein, which can keep the skin firm and elastic. It exists in human skin, bones, teeth, tendons and other parts. On the skin side, it works with elastic fibers to form a reticular support, which provides firm and powerful support for the dermis. With the increase of age, the content of human collagen will gradually lose, and the skin will lose its elasticity and become thinner and aging. Therefore, it can be said that human skin aging is indeed inextricably linked with the loss of collagen.
It is true that some foods containing colloid, such as beef tendon, pig's trotters, chicken wings, chicken skin, fish skin and cartilage, are rich in collagen, but your skin can't benefit much through diet.
2 Oral administration for external use may not be able to beautify
Various oral capsules and oral liquids of collagen have sprung up in the market. Experts believe that oral capsules (oral liquids) are collagen extracted from animal skin by hydrolysis, and after oral administration, they just become amino acid "parts". Due to individual differences and actual needs, the animal collagen or amino acids that everyone eats will never be dominated by the subjective wishes of the users. Therefore, it is obviously exaggerated to take collagen for skin care, beauty care and anti-aging. At the same time, the collagen in protein in daily diet is enough for the actual needs of human body.
It is unnecessary for healthy people and people with normal diet and nutrition to supplement collagen. Aging is a natural law, and no measure can reverse it. We should recognize this.
There are many skin care products about collagen in the market. Adding certain collagen or amino acids into cosmetics can protect the skin and resist aging, but this effect is temporary, and it will not be converted into its own collagen after long-term use.
3 Injection also has certain limitations
The most effective way to "directly supplement" collagen is to inject collagen extracted from calf into the dermis like an injection in cosmetic medicine to repair static wrinkles, such as wrinkles around lips, and scars and pits caused by serious inflammation of acne (acne). However, there are still some limitations:
1. The effect is temporary. Collagen injected into the body will not stay in the dermis all the time, but will be slowly consumed and metabolized, so it can only last for about six months to one year depending on individual circumstances, and then it must be injected again.
2. it is expensive. The cost of an injection of several thousand yuan is not affordable for every consumer.
3. It may cause allergies in a few people. Dermatologists advise people with allergies to do allergy tests first to make sure there are no adverse reactions, and then apply needles. At present, the relatively new method is to inject hyaluronic acid, another powerful moisturizing ingredient, instead of collagen, which can avoid allergic problems and be safer.
4 Supplementation is not as good as prevention
Since the existing methods of supplementing collagen, whether externally applied or orally taken, are not very effective, experts believe that starting with "prevention" means that it is more effective to slow down the loss and degeneration of collagen.
the first is sun protection. Dermatology believes that more than 9% of premature skin aging is caused by improper sunlight exposure.
Secondly, we should eat a balanced diet, especially take more fruits and vegetables containing antioxidants, such as carrots, tomatoes and grapes, and drink more red wine and tea, which can protect collagen in the skin.
finally, don't forget to avoid eating high-fat food. High-calorie and high-fat foods, especially fried foods, are prone to produce free radicals and accelerate aging. If we can eat less of this kind of food, it will reduce the chance of being hurt by free radicals and the risk of dark spots and wrinkles on the skin.
