Skin rejuvenation; What is collagen and how to compensate for its deficiency?

These days, the youth and freshness of the skin is one of the main concerns of people, and the use of skin rejuvenation methods has expanded. Since skin rejuvenation has become commercial and promotional, people are faced with various methods and choosing the best and safest method has become a difficult task.

Many of the presented methods have become popular among people and having the correct information in this field can help you choose safe and healthy and effective methods at the same time.

What do you know about collagen?

Human skin is in its healthiest and freshest state at the time of birth and childhood. Collagen is the main protein in the structure of the skin. This protein makes up 75% of children’s skin and its amount decreases with time and age. Collagen plays a role as a scaffold in the skin and prevents skin sagging. Collagen also makes the skin elastic and plumps the cheeks. Destruction or reduction of this protein causes skin aging and wrinkles.

Factors that reduce collagen in the skin

One of the factors that cause the destruction or reduction of skin collagen is diets aimed at slimming. These diets cause the loss of collagen so that it is impossible to compensate, and people sacrifice the beauty and youth of their skin for fitness. Air pollution, sunlight and rays from monitors, chemicals, depression and lack of sleep are also other factors of losing this protein. All these factors, in addition to wrinkles, cause skin spots and changes in skin pigments.

Collagen in oral form and topical creams

The question is, is collagen really absorbed by the body in oral form or in the form of topical creams? Collagen is a protein with high molecular weight and large size. Therefore, it is not possible to be absorbed through the mucous membranes of the intestines or the skin, because a heavy protein of this size does not reach the main goal that should be absorbed.

The molecular weight of collagen in our skin is 300 kDa, while the commercial collagens in the market have a molecular weight of 30 and up to 90 kDa. You should know that the digestive system can only absorb proteins weighing up to 5 kilodaltons. Therefore, oral supplements cannot be absorbed by the intestine. On the other hand, if they are absorbed, they can only help to build larger collagen molecules and do not replace skin collagen.

Collagen creams that are widely advertised in the market cannot pass through the dense tissue of the skin and reach the destination. Skin tissue does not allow the passage of molecules weighing more than half a kilodalton, while the weight of collagen protein is 300 kilodaltons. However, it can be assured that the absorption of collagen through creams is impossible and only commercial.

According to the above explanations, it can be concluded that the best thing to do is to take care of and prevent skin aging and loss of natural skin collagen, and skin rejuvenation and repair is the second step, which of course should be done carefully in choosing the method.

Other methods of skin rejuvenation

The methods that remove skin damage are called skin rejuvenation, which results in younger, fresher, healthier and clearer skin. The methods used today are both safer and more effective.

Thermal, chemical, mechanical, injection methods and the use of rays and laser are the most effective methods of skin rejuvenation, which we will discuss in the following articles.
