Collagen in the form of cream or gel will be quickly absorbed after application to the skin. This is at least what the producers of cosmetics with this particular protein are trying to tell us. And here an important question arises as to how it will happen if there is no gas exchange through the skin, and collagen molecules are much larger than oxygen molecules, so how will collagen penetrate the skin?

Some time ago, we had the opportunity to watch a special movie about a company, where we can learn that collagen stimulates epidermal cells to produce their own collagen particles. And indeed, such a thing is confirmed by research, but the mechanism of this action is not precisely indicated.

However, it is known that an action that we cannot explain cannot be considered as occurring in a natural and safe way. The film also mentions some experiments with radioactivity labelling, but there is no published work that could prove that such experiences were also a reality.

Yes, skin cells as well as body cells have pores in their membranes, through which various substances can get through, but the collagen lacks the so-called signal sequences. The question arises of special areas that are perceived by specific receptors that could limit the penetration of collagen into cells. Another issue is that there are various cosmetic products that have collagen in their composition in the form of various mixtures.

Not all of these types, however, occur naturally in the skin, which we have already tried to write about. The conclusion may be that collagen is not absorbed. But to some extent this measure will have an impact on the fact that the production of own collagen will be stimulated. Dry skin often results from the fact that unfortunately, in the products we reach for this collagen is very little and practically it will not be noticeable. Some of the ingredients in these products are also of such a nature that they will evaporate very quickly and thus we will not be able to use them at all.
