Can collagen peptides really improve skin?

What are collagen peptides?

Collagen peptides are a type of product produced by extracting, hydrolyzing and refining fresh animal tissues (including skin, bone, tendons, tendons, scales, etc.) rich in collagen, with a relative molecular mass of less than 10,000 Da.

Collagen peptide is a repair type of collagen that can nourish the skin, restore elasticity, anti-aging, antioxidant, and prevent the occurrence of fine lines. It can also improve the body's microcirculation and remove stains, spots, chloasma, and age spots. It can increase the moisture of the skin, brighten the skin color, make the skin firmer, shiny and tender, etc.

It can also enhance the body's resistance and regulate endocrine function.

Collagen peptides are repair-type collagen. As the human body ages, collagen will slowly decrease and be lost.

Therefore, you need to take collagen peptide supplements.

Collagen peptide powder currently comes in two forms: one for oral use; the other for external use. No matter how big the powder is, collagen peptide powder is in a form with a large molecular weight, especially for the barrier function of facial skin.

Therefore, it is difficult for external collagen peptide powder to penetrate into the skin. It only remains on the surface of the skin and may have a moisturizing effect.

Oral collagen peptide powder is related to its molecular weight. Traditional oral collagen mostly comes from pig skin, bovine skin or tendon. In the intestine, collagen peptides are converted into dipeptides or tripeptides, and then passed through Oligopeptide transporters are transported across the mesentery for absorption into the bloodstream and then to the skin.

Why don’t collagen peptides work for some people?

Traditional dermatology believes that it is difficult for such macromolecular substances to maintain therapeutic effects after being absorbed through the intestines.

From a nutritional point of view, the reason why collagen peptides do not work for some people is because they are not broken down and absorbed by the decomposing enzymes in the human stomach. It is difficult for this group of people to absorb collagen peptides, even if they take it There are a lot of collagen peptides, but the effect is very little. The solution is to take them with vitamin B. Vitamins are extremely helpful in promoting the absorption of collagen.

There are also many Korean studies, especially clinical trials, which have found that oral administration of some low-molecular-weight collagen peptides can improve skin hydration and have significant effects on skin wrinkles. However, I advise everyone that when choosing collagen, oral supplements are only a nutritional supplement and cannot play a therapeutic role.

Are collagen peptides and collagen powder the same?

Collagen peptides and collagen protein powder are two different substances. The difference lies in different extraction methods, different effects, different contraindications, etc. It should be noted that they should be used under the guidance of a doctor. 1. Different extraction methods. Collagen peptides are extracted from pig skin, while collagen protein powder is extracted from cow hide. 2. Different functions: Collagen peptides can support and repair the skin, while collagen protein powder can lock in moisture and maintain skin elasticity. 3. Different taboos. If you are allergic to collagen peptides or collagen proteins, it is generally not recommended to use it to avoid allergic reactions. At the same time, if the patient has gastrointestinal dysfunction, it is not recommended to consume it to avoid increasing the burden on the gastrointestinal tract and causing abdominal distension. , abdominal pain and other discomfort symptoms.

People who should avoid collagen peptides

Collagen peptides have no obvious side effects on lactating women and will not have any impact on children. Generally, you can drink them, but you must pay attention to the dosage.

It can help the mother stop bleeding and heal wounds, repair stretch marks, tighten skin, prevent breast sagging and enhance elasticity, improve anemia, etc.

It is also beneficial to children and can help supplement amino acids that are not contained in the mother's body.

Although taking collagen during lactation generally does not cause the return of milk, it is best not to take it in large quantities, because the ingredients in collagen products may reduce the quality of milk, and if taken in large amounts, they may be passed to the baby through milk.
