Our vegan collagen has been broken down into what is called a peptide. While it is correct to say that a straight collagen molecule is actually too large to absorb through skin, which is why so many people choose to eat animal based collagen-rich bone broth or take collagen supplements, once collagen is broken down into a peptide, the results are much different as the molecules are far smaller. Our Vegan Collagen has been shown by a third party lab to increase skin moisturization in as little as 2 weeks, and leaves skin with a firmer appearance. Our Vegan Collagen collection combines incredible support ingredients in each product including hyaluronic acid, flower extracts, vegan squalane, Camellia japonica which is also known as Tsubaki (soo-baw-kee) in Japanese and known for it's remarkable ability to retain moisture and absorb into the skin (because its composition is similar to sebum). We hope that helps! As with all of our products, we have a 100% satisfaction guarantee. So if it does not meet your expectations, you can return it to us!
