Collagen supplements Vs Collagen creams?

Collagen first came to prominence in the skin world through its use on open skin wounds. By incorporating collagen into wound dressings, it was found that the collagen could be taken up into the skin and promoted faster healing.  

Collagen in creams

When it comes to using collagen in creams for skin health or anti-ageing, the research is not nearly as conclusive. Collagen itself is a huge molecule that cannot be absorbed by the skin as it’s too large.

Hydrolysed collagen, composed of much smaller fragments of collagen, is able to penetrate only to the outer layer of the skin, where it can provide good moisturising properties and improve some of the visible signs of ageing such as wrinkles, dryness, and the loss of elasticity.

If you really want your collagen to make a difference, you need to take it internally.

The type of collagen definitely matters! The size of the collagen peptides directly affects their absorbability and antioxidant capabilities. The lower the molecular weight – the better. The best supplements have a molecular size of between 1 and 3 kDa, giving up to 95% absorption. 

Several studies have shown that once absorbed, the amino acids contained in hydrolysed collagen peptides can be transported through the bloodstream around the body and utilised in many different areas.

Whether it’s gut health, bone or joint strength, or maybe the anti-ageing skin effects you’re looking for, consistent use of a daily liquid collagen supplement is definitely the best way to achieve effective results.
