Shereene Idriss breaks down why collagen banking doesn't work: your body doesn't store collagen like fat, whole collagen molecules are too large to penetrate skin, and topical products can only hydrate the surface. Sunscreen is the real way to preserve what you have.
Collagen banking. Save up our collagen now so we can have way more later. Unlike fat, we cannot store collagen. Here's the actual biology. We produce collagen, eventually use it up and break it down, and then create more. The goal is really keep production high of collagen while keeping the breakdown low. Number one thing that you can do is sunscreen. Collagen molecule itself is way too big to ever penetrate your skin to help you make more collagen. Unless it's a collagen peptide or a precursor, it's never going to happen. The collagen itself is going to offer nice hydration, which is great, but if you're expecting it to bank collagen and help with firmness over time, you're wasting your efforts and your hard-earned money. All of these things that you're being served, they're never going to save you. In two words, it's manufactured panic.
