Creams and aesthetic treatments can make us look beautiful skin and delay the skin aging process, and you never know where the eternal and sought-after elixir to have a younger dermis can hide. If you are one of those who separated the skin from the fish at dinner, perhaps you should rethink it, according to a study by the Oregon State University (USA), which has discovered that the consumption of hake from the Pacific, specifically from one part of it, the skin, is useful in preventing wrinkles.
The research, which has been published in the journal Marine Drugs, analyzed the gelatin present in the skin of the Pacific whiting, also called hake. Although the consumption of this mild white fish is not very common in the United States, in Europe it has become the eighth most ingested species, with Spain being the second European consumer after the Portuguese.
“Fish skin is an abundant resource that we already know has valuable nutritional properties. But we wanted to find out what additional potential value could be found in something that is traditionally considered a by-product,” said Jung Kwon, lead researcher on the study.
Do not discard the skin of the fish, it has many nutrients
And it is that, this part of the fish is often discarded, when a large number of nutrients with great properties go into it. In this study, the molecular pathways that cause wrinkles in the skin at the cellular level have been analyzed. Ultraviolet radiation (UV) promotes the appearance of this type of furrows in the skin, as it has the ability to break down the collagen in the skin.
Hake skin promotes antioxidant activity in skin cells and reactivates collagen synthesis, which delays skin aging
To learn more, the researchers extracted gelatin from Pacific fish and then examined its impact on antioxidant and inflammatory responses and pathways known from other studies to degrade collagen and promote collagen synthesis—that is, they are able to to order and relate the chains of this protein.
The results showed that the gelatin from the Pacific hake skin prevented the activation of the process by which collagen degrades, which is accelerated by UV radiation. In addition, it promoted antioxidant activity, which is the process by which cell damage is prevented or delayed.
On the other hand, it had anti-inflammatory effects and reactivated the collagen synthesis pathway that had previously been suppressed by UV radiation. The tests were carried out in a human cell model, so the next step in the work is to test the effects of hake skin on animals, so that, if they are beneficial, the great leap can be made to human trials.
