Collagen is the most abundant protein in all animals. For humans, it makes up one-third of all protein in our body and three-quarters of the weight of dry skin [1,2]. There are at least 16 types of collagens, but about 80-90% of the collagen found in our body are types I, II and III.
Collagen helps our body tissues such as muscles, bones, and joints withstand stretching and absorb shocks . The recent trends on inner beauty have led to increasing scientific researches on its benefits for the human skin. Many researches conducted have proven and concluded the positive effects of collagen on the skin.
Areas Of Scientific Research
Collagen makes up most of the content of our skin and has been proven to improve skin elasticity and dryness.
Researches have shown that the total collagen content in our skin falls by 1% per year. As we age, the collagen protein network fragments, causing it to be irregular and disorganized. Collagen synthesis also declines gradually. The fall in collagen type I level is the reason behind skin aging and the formation of wrinkles, skin dryness and less elasticity [4,5,6].
The skin also gets damaged over time from temperature changes and UV radiation. UV-A and UV-B light penetrate our skin, causing photoaging and the collagen on our skin to fragment . To stop skin degradation and aging, we need to induce collagen production and increase the collagen density in our skin.
Taking collagen supplements have shown in studies to improve skin barrier function and promote the synthesis of collagen by our body , restoring the structure of the collagen network. Taking Vitamin C is also a proven way to increase the production of collagen types I and III. [9,10]
The end results of these studies have shown significant improvement for skin elasticity and hydration . The effects continue to persist for months even after supplementation had stopped .
Collagen is an important protein found in abundance in our joints and cartilage, made up of mostly type I and type II collagen. Studies have shown that specific use of collagen can help in the treatment in arthritis [13,14] and reduce joint pain. Its high level of safety makes it attractive as an agent for long-term use in these chronic disorders.
One small clinical trial  has shown the effectiveness of reducing joint deterioration in athletes. The results of this study have implications for the use of collagen hydrolysate to support joint health and possibly reduce the risk of joint deterioration in a high-risk group. Despite the study's size and limitations, the results suggest that athletes consuming collagen hydrolysate can reduce parameters (such as pain) that have a negative impact on athletic performance.
Collagen used to be extracted from mammals; the gelatine you eat from bone marrow contains collagen. However, collagen supplements were uncommon due to the cost of extraction from high difficulty and low availability. Moreover, there is a risk of transmitting animal diseases such as Mad Cow Disease or Swine Flu by taking collagen from mammals.
On the other hand, most supplements and cosmetics in the market now use collagen from marine animals due to its abundance from discarded fish skin and bones. It also carries no risk of any transmitted disease [16,17].
Marine collagen is excellent for skin protection due to its compatibility with humans, counteracting the harmful effects UV radiation has on our skin.
