Active Ingredients: Marine Collagen

Something under the sea is better than anything up there!

Doesn’t it feel like the word collagen has been such a buzzword in skincare, be it in skincare ingredients or the benefits that certain skincare products can bring for your skin. Well, there’s a reason for that.

As we age, the natural collagen in our bodies will start to deplete and produce less. Collagen can be found throughout our entire body, within the skin, muscles, ligaments and blood vessels. So, the assumption that collagen is only necessary or beneficial for cosmetics purposes is false, collagen is vital for our health and entire body. It is responsible for nimble, healthy joints and skin elasticity and moisture. With our body producing less collagen, in terms of our skin, this can lead to sagging or dull-looking skin. which is why there are a variety of topical treatments and supplements that promote collagen production or are infused with collagen derivative ingredients.

There are various types of collagen and it depends on where the collagen is sourced from. Some are bovine (cows), porcine (pigs), chicken and fish (marine). And this blog, we’re gonna be bringing the attention to marine collagen.

Marine collagen is a Type I collagen derived from fish collagen peptides. Marine collagen has recently been the go-to pick due to its bioavailability. Bioavailability is the rate at which it is absorbed into the body, and when orally consumed it enters the bloodstream the fastest. Also, Type I collagen is preferred for topical use because our skin is made up of 85% Type I collagen, whereas other collagen types are mostly Type II which are more beneficial for joints, not really doing much for the dermis (skin). The more Type I the body has, the more it can help stimulate natural collagen synthesis which can improve skin health, complexion and texture over time.

There is illusion that by introducing collagen to the skin, it works to replenish whatever collagen that our is lacking but isn’t how it goes. Well, for skincare products at least and will be discussed below. Supplements and other dietary products are another topic as the formulations and chemistry compounds are different.



Boost moisture levels

  • As stated above, marine collagen, or any collagen, doesn’t work by instantly replenishing the lost collagen, instead they work to mainly deliver moisture to the skin, upping the moisture levels. With increased moisture, the skin will naturally appear plumper and more radiant. 

Improves elasticity

  • As with most collagen promising products, marine collagen can improve elasticity. This benefit mainly comes from the increased moisture and hydration in the skin. By boosting the skin’s elasticity, it reduces the appearance of wrinkles and fine lines. This is also why collagen is present is many anti-aging products as hydrated skin is healthier and younger-looking skin. 

Supports the healing process

  • Marine collagen can also aid with the skin’s healing process, helping repair facial wounds, sun damage and other trauma.

Strengthens skin barrier

  • Marine collagen can help strengthen and thicken the layers of the dermis and enhance the protective barrier. This leads to better moisture retention and improving the overall skin health.


What to note?

  • It is important to remember that the idea of collagen skincare does not work by penetrating the skin and replenishing those that were lost, although there are R&D focusing on that, not enough evidence supports this idea. How collagen works is by reinforcing the dermis and protective barrier to better retain moisture. This causes the skin to appear fuller and more lifted, hence, less fine lines and wrinkles.
  • We recommend using marine collagen with “cell growth messengers” such as retinol, retinoids, peptides or Vitamin C to signal the cells to create collagen. Marine collagen is also suitable to use in conjunction with most ingredients but we would still advise conducting a prior patch test.
