Collagen is the synonymous of healthy, young and wrinkle-free skin. Unfortunately, with age, it begins to disappear in our skin. Can and how we  can slow down this process?

The increase in the amount of collagen is the goal in cosmetology, in aesthetic medicine and in everyday care. This is also the goal of manufacturers of professional and retail products.

What is collagen?


Collagen, next to elastin, is produced by the cells of the dermis lying under the basement membrane, called fibroblasts. There are as many as 9 types of collagen in the skin, but two are the most important for us - collagen type I and collagen type III. Each of them is made of nearly a thousand amino acids.  Moreover, it consists of three polypeptide chains bound in a triple helix. When it comes to the amino acids that build it, there are mainly proline, hydroxyproline, lysine and glycine.

What is the function of collagen?


Collagen in the skin is responsible for its strength, elasticity and smoothness. Unfortunately, it is assumed that 1% of it disappears every year and wrinkles start to appear, the skin becomes more dry, less firm and elastic. This is the natural aging process of the skin, but there are also other factors that can accelerate this condition.


Factors accelerating the process of collagen disappearance?


Exposure to UV radiation, environmental pollution, including smog, and tobacco smoke. Another reason may be the lack of the right amount of protein in the diet, nutritional deficiencies, excessive supply of simple carbohydrates and the glycation process that occurs under their influence. And very important to mention, hormonal imbalances, including the decline of estrogen during menopause.

What collagen is used in cosmetic products?


Natural animal collagen. It is most often used in the form of a hydrolyzate, sometimes in the form of flexible sheets of collagen fibers or in a freeze-dried form. Obtained in this way differs in the structure of protein chains. Its advantage is the ability to bind to the keratin of the stratum corneum, excellent tolerance, high safety of use and moisturizing properties. It has film-forming properties - it creates an occlusive layer on the skin surface, prevents water evaporation, increases the hydration of the epidermis and its permeability.


Native collagen - the second type, also called marine collagen. It is usually obtained from the skins of marine fish. It is the most modern and biologically active form of collagen with a slightly smaller structure, and thanks to this it also has the ability to penetrate into the deeper layers of the skin. In addition, it has a moisturizing and firming effect.


Microcollagen - here we already have fragments of proteins with a small particle size that imitate natural collagen, stimulate fibroblasts and start the process of its synthesis. What's more - they are popular oligopeptides with a signaling effect. They are often combined with other peptide complexes and high molecular weight collagen.


Are there any downsides to using this type of collagen?


The disadvantage of natural animal collagen is the inability to overcome the epidermal barrier. The fact is that the stratum corneum only allows molecules weighing less than 5,000 daltons, and collagen has a mass up to ten times higher. This means nothing else but the inability to replenish collagen in the skin and affect the structure of the dermis. If you use cosmetics that contain this type of collagen, do not be deluded that it will be delivered to the skin layers and will rebuild or increase the amount of our natural collagen. Moisturizing the skin will increase its tension and elasticity. The surface will be evened out and the visibility of wrinkles will be reduced. This is a cosmetic effect, not a long-term one.


But what cosmetics are worth investing in?


If you want to take full advantage of collagen and use cosmetics that contain it, check the source of collagen and the type of collagen used by the manufacturer before investing in any preparation. If you choose drugstore cosmetics, don't wear anything more than moisturizing. Of the brands that use native collagen (and it is worth investing in such collagen in cosmetics), I know one that I also had the opportunity to work with and use personally.

What are collagen boosting products?

With the knowledge that collagen production is essential for maintaining younger, more healthy looking skin, it is important to try to slow down the deterioration of collagen within the body and attempt to boost overall collagen production.

Collagen products which are actually consumed have shown promising results in helping to improve the appearance of ageing skin.
