Sources give competing estimates of collagen loss by age 60, ranging from about 30% to 'more than half', so 'about half' falls inside the range and is not cleanly confirmed or refuted. The extraction faithfully matches the post's wording ('so many people have lost about half of it').

A detail. The sources confirm the gist; the verdict faults a detail such as a date, number or wording.

What we found

Contradicts. Other sources put the loss by age 60 lower: Organised estimates about 30% lost by 60, and a YouTube transcript estimates 30–40% of dermal collagen lost by 60.[1][2]

Supports. A health blog says most people have lost roughly half the collagen they had in their twenties by age 60, and another says more than half may be lost by 60.[3][4]

Context. The Conversation reports up to about 30% skin collagen loss in the first five years after menopause, a window narrower than the claim's age-60 timeframe. Cleveland Clinic gives no percentage for age 60 at all.[5][6]

Context. Most sources are unrated blogs or commercial sites with no primary study behind the half-by-60 figure, so the estimates rest on weak and inconsistent evidence.[1][2][3][4][7]
