What the evidence says
- Timeline's listing cites an 8-week randomized controlled trial of 36 healthy women aged 40 to 65 (up to 15% less visible wrinkles) and a 3-week user trial of 30 women. Neither appears as a published paper: a PubMed search on 2026-09-14 found no published human trial of urolithin A on skin.
- The 48% on Timeline's own page is one participant in the brand's 8-week before-and-after study of 132 people, with no control group described.
Brand-reported results, not independent studies.
