Nearly every collagen supplement sold in the UK says 'hydrolysed' on the pack. Here's what that actually means — and why the word matters more than the marketing around it.

The collagen itself is usually animal-derived, but the jelly texture isn't gelatine — checked against the real ingredient panel for all six UK-available sticks we track.

A newer wave of jelly sticks uses PDRN, an ingredient with real clinical research behind it — but that research is about injections, not eating it. Here's the honest gap.

Whole collagen is far too large to pass through the skin's outer layer. Smaller fragments are a murkier story, and what's on a cream's label is a different question from what happens when you eat it.

A collagen jelly stick is something you eat. A collagen balm stick or wand is something you put on your skin. They share a word and little else — here's how to tell which one you're after.

The skin-elasticity story doesn't hold up as the reason to take collagen later in life. The genuinely useful evidence for this age group is about joint pain and muscle strength — at doses well above a single stick.

Collagen marketing skews almost entirely female. The research doesn't — men-specific studies exist for muscle strength and joint pain, at doses most products don't come close to. Here's the honest version.
