I skimmed that Neuvera peptides vs collagen guide this morning over my latte. Here’s the logical gap I spotted right away. They state applying collagen topically isn’t the same as using ingredients intended to support collagen-related processes. That’s technically true, but they skip a key point. Small collagen fragments can actually penetrate the outer skin layer. Not full molecules, sure, but framing topical collagen as having no link to collagen support is a stretch. I’m not fully buying that part, wait, no, scratch that. I’m not fully buying that absolute stance. Need more peer-reviewed data to back it up properly.
