Consumer advice
Don't expect dramatic skin or joint changes from this powder - oral collagen is digested like any other protein into amino acids, and the "goes straight to your skin" framing isn't how digestion works. If you want to try it, this eBay listing at $9.17 is cheaper than most listed alternatives on this same page (which range $13-$34), so price-wise it's a fine deal for what it is. Check the expiration date and seller condition claims since it's a secondhand/overstock item with no returns accepted.
Claims vs Evidence
