Today there is a lot of talk about collagen. You must have come across a cosmetic or nutritional product that advertises collagen as a magical active ingredient. Do you know what collagen is and why it is important?

Collagen is structural protein, which represents almost a third of the protein in our body. It is one of the main building blocks of the skin, bones, muscles, teeth and other parts of the body. It is easiest to imagine it as a kind of glue, which binds tissues together and gives them flexibility. We know what 16 types of collagen, which play different roles in the body. They are the most important:

  • Tip I: Makes up 90% of collagen in the body and gives structure to the skin, bones, teeth and connective tissues.
  • Type II: It is made up of more sparsely distributed fibers and is found in elastic cartilage. It acts as a cushion for the joints.
  • Tip 3: Supports the structure of muscles, organs and arteries.
  • Tip IV: Helps with filtration and is present in different layers of the skin.

The role of collagen in the skin

Collagen is located in the middle layer of the skin, which is called the dermis or epidermis. It gives collagen together with elastin to the skin mechanical support and consequently takes care of hers firmness in smooth appearance. The production houses of collagen in the dermis are cells called fibroblasts. Collagen fibers are formed by the binding of two amino acids - PROLINE in GLYCINE when present Vitamin C.

The amount of collagen in the skin is genetically determined, but it depends on it strongly influenced by different external factors. Unhealthy lifestyle, sun exposure and smoking they trigger the formation of free radicals in the skin, which damage collagen fibers and further accelerate its breakdown. In addition to that with aging collagen production naturally decreases as well as his quality.

After the age of 21, the production of collagen should begin to decrease by 1% per year. The latter is with the naked eye most noticeable right on the skin, as it becomes less firm and elastic and consequently wrinkled. A reduced collagen level not only affects wrinkles, but also plays an important role in formation of cellulite. Collagen fibers in the subcutaneous tissue act as a binder between fat cells, and changes in their structure are externally visible as orange (wrinkled) skin.

How can we stimulate the production of collagen?

Unfortunately, they are collagen molecules too big, to introduce them into the skin with topical application (admission of the active ingredient only on a certain place of the skin), as they cannot penetrate through the epidermis into the deeper layers of the skin. The good news is that you can we influence the increased synthesis of collagen fibers namely:

  • Food

Eating foods rich in prolinom (eggs 🥚, asparagus, mushrooms 🍄), glycine (meat 🍗, fish 🐟, eggs 🥚), and vitamin C (citrus 🍊🍋, paprika, kiwi 🥝), because with this we provide a supply of the basic building blocks of collagen and thus we positively influence its production.

  • Cosmetics

Also with skin care we can successfully fight against wrinkles and cellulite. As already mentioned, free radicals are one of the main culprits for the breakdown of collagen. Usage cosmetics containing antioxidants it is so great for collagen protection. They are antioxidants chemical compounds (flavonoids, phenols, skvalen, vitamin A in E, ...), which fight against free radicals and consequently protect collagen. With cosmetics, you can use vitamin C - ascorbic acid  we also influence the formation of collagen fibers. Vitamin C acts as a catalyst for the formation of collagen, which means that the reaction does not proceed without it. The use of cosmetic products containing ingredients with a high content of ascorbic acid (lemon essential oil 🍋, brown algae extract, rosehip oil) so stimulates collagen synthesis in the skin, consequently slows down aging in improves its appearance.

The skin has many important physical functions (protection against external factors, regulation of body temperature, type organ, important part of the immune system). In addition, it also determines the external appearance and thus has a strong influence on a person's self-confidence. Keeping the skin in good condition is important both physically and psychologically. The saying goes with skin "Prevention is the best cure", therefore, by following the above tips and proper skin care slows down the loss of collagen and with this we help to make it our skin healthy, firm in youthful.
