What is known, and what is missing
Measured on: wrinkle depth in photoaged skin (the anti-ageing job this base scores 7).
Reading the cited paper removes the number rather than confirming it. Hoppe is a Beiersdorf in-house biochemistry paper whose business is epidermal penetration, weak photon emission, keratinocyte thiol depletion and collagenase suppression; the entire human wrinkle result is a single sentence saying a reduction in wrinkle depth was also shown, with no subject count, no statistics and no control arm. A single uncontrolled manufacturer observation cannot carry a multi-month bucket, and 0.3% over six months is where the application stopped, not where anything began. The other topical work from the same group measures skin Q10 levels and antioxidant capacity rather than wrinkles over time, and the placebo-controlled wrinkle trials that do exist are of oral supplementation, a different route. What is missing is any vehicle-controlled topical study with timed endpoints.
