In skincare, topical collagen does a great job of moisturising and replenishing the skin, but is unable to penetrate the surface due to its molecular size. As an ingestible, collagen works on a deeper level, crossing through the gut lining into the bloodstream to improve overall skin health and reverse the hallmarks of ageing. It does this by increasing the density of fibroblasts, the cells responsible for rebuilding connective tissue, including collagen.

When it comes to ingestible collagen, collagen benefit studies have been done with bovine, porcine and marine collagen. These all contain collagen types I (which accounts for 90% of your body’s collagen) and III (which supports the structure of muscles, organs and arteries).

A considerable number of research studies have been done on marine collagen. And skin professionals agree. “Marine collagen is absorbed up to one-and-a-half times more efficiently than collagen sourced from cows or pigs, meaning it has superior bioavailability. It’s also hydrolysed, a process that converts collagen into a peptide powder with a low molecular weight. The lower its molecular weight (or the smaller the collagen particles), the easier collagen is to absorb,” says dietician Chloe Mcleod. This means your body is able to achieve optimal skin results – fine lines and wrinkles are smoothed, elasticity is enhanced for a youthful glow and skin firmness is increased delivering a visibly lifted complexion.

Can collagen improve skin? Yes. But similarly, it can help heal brittle and tear-prone nails. We know that consistent manicures and life’s daily demands leave nails feeling weak and dulled. And while topicals can superficially heal and hydrate,long, strong nailsstart on the inside. By supplementing collagen, you can combat damaged and compromised nails, and improve your overall nail health.
